Best Free Mobile App Builders in 2026

Published October 25, 2026 · Last updated October 25, 2026

Every mobile app builder lets you start free, but publishing to the App Store or Google Play always needs a paid plan. Superapp is the best free mobile app builder for iPhone: it is the only one that builds a native Swift app from a description, submits it to the App Store for you, and then markets it on autopilot.

The Best Free Mobile App Builder in 2026: The Short Answer

Superapp is the best free mobile app builder if you want a real iPhone app: it is "free to start with free credits in most countries," turns a plain-English description into a native Swift and SwiftUI app for iPhone, iPad, Apple Watch and Mac, prepares and submits the App Store build when you upgrade to Pro at $25 a month, and on its Max plan runs a marketing agent that brings users. For iPhone and Android from one project, Adalo, FlutterFlow, Bubble and Thunkable all offer free plans for building and paid plans for publishing. Bravo Studio suits designers working from Figma. Glide, Softr and Jotform Apps build web apps that install from a browser rather than an app store. MIT App Inventor and Kodular are free, block-based tools aimed at learning and Android.

Quick answer: What is the best free mobile app builder? Superapp, for native iPhone apps: free credits to start, about one screen per credit, native Swift you can export as an Xcode project, and App Store submission handled on Pro at $25 a month. It is the only builder here that also gets you users after launch, with its Selfdrive marketing agent on Max. No builder publishes to the stores for free: Apple charges $99 a year and Google Play a one-time $25 fee, and every builder below needs a paid plan to publish. For both stores from one project, Adalo, FlutterFlow, Bubble and Thunkable lead; for web apps without an app store, Glide, Softr and Jotform Apps.

The 12 free mobile app builders at a glance

Prices are from each vendor's own pricing pages, checked on October 25, 2026. Apple's $99 yearly developer fee applies to the App Store, and Google's US$25 one-time fee to Google Play.

What Does "Free" Really Mean for a Mobile App Builder?

"Free" means free to build, not free to publish. Every builder in this comparison follows the same pattern:

So the useful question is not "which builder is free?" but "how far can I get for free, and what does it cost to publish?" A good free plan lets you build enough of your real app to know whether the builder fits before you pay.

The 12 Best Free Mobile App Builders, Reviewed

Every builder is reviewed on the same points: free plan, cheapest plan that publishes, what it builds, store publishing, code export, getting users, what to watch out for, its own words, the free plan in practice, publishing step by step, a pitfall, who it is not for, and who it is best for.

1. Superapp: Best Free Mobile App Builder for Native iPhone Apps

Superapp is the only builder in this comparison that turns a plain-English description into a native Swift app, submits it to the App Store for you, and markets it on autopilot after launch.

Free plan: "Superapp is free to start with free credits in most countries," and "About one credit generates one screen," so you can build and preview real screens before paying. Superapp notes that in some regions the free plan is not available.

Cheapest plan that publishes: Pro at $25 a month with 50 credits and automated App Store publishing. "You can build and ship commercial apps on any paid plan."

What it builds: native Swift and SwiftUI as a complete Xcode project for iPhone, iPad, Apple Watch and Mac, plus a website for your app from the same project. Superapp runs Macs with Xcode in the cloud, so you do not need a Mac.

Store publishing: Superapp prepares the build, metadata, screenshots, privacy declarations, App Store optimization and submission for you, and takes the app through App Store review. You need your own Apple Developer account at $99 a year.

Code export: the Xcode project can be exported "on any plan."

Getting users: Selfdrive, Superapp's AI marketing agent for iOS apps, is included in Max at $100 a month. It runs Apple Ads within your budget, App Store optimization, a website with SEO content, and creator campaigns, and sends one email every morning with results.

Watch out for: Apple platforms only, no Android; extra credits ($18 for 30) are for paid plans only.

How building works:

1. Describe the app in plain English: who it is for, the screens, the data and the rules.
2. Review the generated SwiftUI screens and ask for changes one at a time.
3. Add accounts and data with Superapp Cloud, or connect your own Supabase.
4. Add iPhone features such as push notifications, widgets, Live Activities, HealthKit, an Apple Watch app, or subscriptions and in-app purchases.
5. Upgrade to Pro, connect your Apple Developer account, and let Superapp prepare and submit the App Store listing.
6. On Max, turn on Selfdrive to bring users.

In its own words: "Superapp is free to start with free credits in most countries."

Free plan in practice: describe your app, generate its main screens, ask for changes and watch the result in an iOS Simulator preview. Because about one credit generates one screen, spend free credits on the screens that define your app, not on cosmetic tweaks.

Publishing, step by step: upgrade to Pro, connect your Apple Developer account, and Superapp prepares the build, screenshots, description, privacy details and keywords and submits the app for review. If Apple asks for changes, Superapp says it takes the app through review "with hands-on help from the team if needed."

Pitfall: the free plan is for building and previewing; you need a paid plan to ship.

Not for: anyone who needs an Android app from the same project.

Best for: non-coders who want a real native iPhone app in the App Store, and users after launch.

2. Adalo: Best Free Builder for Database Apps on Both Stores

Free plan: Adalo's free plan is "free forever," with 500 records per app, unlimited test apps, one free app build and five prompts a month for its AI builder, Ada.

Cheapest plan that publishes: Builder at $65 a month or $624 a year, the first plan that lets you "Publish to the stores and web," with 2 published apps.

What it builds: native iOS and Android builds and a web app from one project, with a built-in database.

Store publishing: a guided workflow through App Store Connect and Google Play Console.

Code export: not listed; Builder shows a sample of Ada's code and Business lets you view all of it.

Getting users: no marketing tools documented.

Watch out for: some Adalo blog posts still say plans start "at $36/month," but its pricing page lists Builder at $65 a month or $624 a year.

In its own words: Adalo says you "publish real native iOS (IPA) and Android (AAB) builds, not web wrappers."

Free plan in practice: build a database app with up to 500 records, test it as often as you like with test apps, and try Ada's AI with five prompts a month.

Publishing, step by step: upgrade to Builder, connect your Apple and Google developer accounts, and follow Adalo's guided workflow through App Store Connect and Google Play Console.

Pitfall: Builder allows 2 published apps; a third app needs Business at $200 a month.

Not for: anyone who wants native Swift, Apple Watch apps or code they can take elsewhere.

Best for: small businesses building directories, bookings or list-based apps for iPhone and Android.

3. FlutterFlow: Best Free Builder for Teams That Want Flutter Code

Free plan: 2 projects, 5 AI requests in total, and web publishing; code download and store deployment are not included.

Cheapest plan that publishes: Basic at $39 a month, which adds code download and App Store deployment.

What it builds: Flutter apps for iOS, Android and web.

Store publishing: deployment with an App Store Connect API key you create; you finish the listing and submit in App Store Connect.

Code export: Flutter code download on Basic.

Getting users: no marketing tools documented.

Watch out for: no database included; team features on Growth cost $80 for the first seat plus $55 per extra seat.

In its own words: FlutterFlow's AI lets you "Describe a page or component and get real FlutterFlow widgets in your app's theme, in about a minute."

Free plan in practice: two projects, a handful of AI requests and web publishing are enough to learn the editor and build a prototype.

Publishing, step by step: upgrade to Basic, create an App Store Connect API key, deploy from FlutterFlow, then finish the listing and submit in App Store Connect; Google Play follows a similar flow.

Pitfall: five AI requests in total go quickly, and you still need to set up a backend.

Not for: non-coders who want the builder to handle data, publishing and marketing for them.

Best for: product teams with some technical help who want a Flutter codebase.

4. Bubble: Best Free Builder for a Web App With Mobile Apps

Free plan: a development plan with 50K workload units a month for building and testing; you cannot publish live apps on it.

Cheapest plan that publishes: Starter mobile at $42 a month billed annually or $49 monthly; web and mobile Starter is $59 or $69. Bubble says "To publish to the App Store and Google Play Store, you need a Mobile or Web & Mobile plan."

What it builds: web apps and React Native mobile apps on one backend.

Store publishing: Bubble builds and uploads to App Store Connect; you complete the listing and submit for review there.

Code export: none.

Getting users: no marketing tools documented.

Watch out for: usage is metered in workload units.

In its own words: "In Bubble, native mobile apps run on React Native."

Free plan in practice: build and test your web app and mobile app in Bubble's editor, within 50K workload units a month.

Publishing, step by step: upgrade to a Mobile or Web and Mobile plan, connect your Apple key, let Bubble build and upload, then add the listing and submit in App Store Connect.

Pitfall: workload units make your bill depend on how much your app is used.

Not for: anyone who wants to leave with their code; Bubble has no export.

Best for: founders whose product is a web app that also needs mobile apps.

5. Thunkable: Best Free Builder for First Apps and Classrooms

Free plan: 3 public projects, 5 screens per project and 2,000 AI tokens; publishing is for paid plans.

Cheapest plan that publishes: Builder at $37 a month billed annually or $59 monthly, with one live published app. Accelerator ($18 to $19 a month) does not include a live app; Advanced ($99 annually or $189 monthly) allows unlimited apps.

What it builds: cross-platform iOS and Android apps with an AI builder and visual blocks.

Store publishing: builds and sends to App Store Connect with your API key; you finish the listing and submit.

Code export: not listed on its pricing page.

Getting users: no marketing tools documented.

Watch out for: free projects are public; Thunkable says published apps become unavailable if your subscription expires.

In its own words: with an App Store Connect API key, your app is "built and sent to your App's page on Apple automatically."

Free plan in practice: three public projects with five screens each is enough for a small app or a classroom exercise.

Publishing, step by step: upgrade to Builder, connect your Apple and Google accounts, publish from Thunkable, then finish the listings and submit.

Pitfall: free projects are public, so do not build a private business idea on the free plan.

Not for: apps with many screens or anyone who needs more than one live app on a budget plan.

Best for: students, teachers and first-time builders.

6. Bravo Studio: Best for Designers Turning Figma Files Into Apps

Free plan: "free, forever," with up to 15 screens per app and "No App Store builds."

Cheapest plan that publishes: Solo at $22 a month, with native iOS and Android builds and store publishing.

What it builds: native iOS and Android apps from designs you create in Figma.

Store publishing: IPA and APK builds for you to submit to the stores.

Code export: React Native source through Bravo MCP on every plan; Bravo To Go, a done-for-you build at $999 per app, includes full source.

Getting users: no marketing tools documented.

Watch out for: you design every screen in Figma first; data and logic need an API or backend.

In its own words: Bravo's free plan is "free, forever," with "No App Store builds."

Free plan in practice: connect a Figma file, build up to 15 screens per app, and preview on your phone.

Publishing, step by step: upgrade to Solo, generate the iOS and Android builds, and submit them to the stores yourself.

Pitfall: every screen starts in Figma, so changes mean going back to your design file.

Not for: non-designers, or anyone who wants to describe the app instead of drawing it.

Best for: designers and agencies who already work in Figma.

7. Glide: Best Free Builder for Apps From Spreadsheets

Free plan: 2 team members and 10 projects, with no published apps.

Cheapest paid plan: Basic at $25 a month; Plus is $50 and Pro is $125.

What it builds: "Glide apps are Progressive Web Apps (PWAs)."

Store publishing: publishing to the App Store or Google Play "is not supported."

Code export: not listed.

Getting users: no marketing tools documented.

Watch out for: no app store listing, so people cannot find your app by searching the stores.

In its own words: "Glide apps are Progressive Web Apps (PWAs)."

Free plan in practice: connect a spreadsheet and build up to 10 projects for yourself and one teammate.

Publishing, step by step: share a link; people add the app to their home screen from the browser.

Pitfall: the free plan has no published apps.

Not for: anyone who needs an App Store or Google Play listing.

Best for: teams turning spreadsheet data into simple internal apps.

8. Softr: Best Free Builder for Client Portals

Free plan: 3 builders and 5 app users in total.

Cheapest paid plan: Basic at $19 a month billed annually or $25 monthly.

What it builds: web apps and progressive web apps, often on Airtable or other data sources.

Store publishing: not supported; apps install from the browser.

Code export: not listed.

Getting users: no marketing tools documented.

Watch out for: user limits rise with each plan.

In its own words: Softr describes its apps as web apps and progressive web apps built on your data.

Free plan in practice: build a portal or internal tool for up to 5 app users.

Publishing, step by step: publish to the web and share the link; a custom domain needs a paid plan.

Pitfall: user limits mean costs grow with your audience.

Not for: consumer apps that need to be found in the app stores.

Best for: client portals and internal tools built on existing data.

9. Appy Pie: Best for Template Apps for Small Businesses

Free plan: a 7-day free trial for non-commercial use.

Cheapest plan that publishes: per-app pricing of $16 (Basic), $36 (Gold) and $60 (Platinum) a month; iOS needs Platinum.

What it builds: template-based apps for industries such as restaurants, fitness and churches.

Store publishing: iOS publishing on Platinum.

Code export: not listed.

Getting users: no marketing tools documented.

Watch out for: each app needs its own subscription.

In its own words: Appy Pie offers a "7 day free trial" for non-commercial use.

Free plan in practice: try a template for a week and see whether it fits your business.

Publishing, step by step: choose a per-app plan (Platinum for iOS), and Appy Pie's team helps with the first store submission under your developer accounts.

Pitfall: each app is a separate subscription.

Not for: apps that do not fit a template.

Best for: small businesses whose app fits one of Appy Pie's templates.

10. Jotform Apps: Best Free Builder for Forms and Data Collection

Free plan: included in Jotform's free Starter plan, with 5 forms, 100 submissions a month and Jotform branding.

Cheapest paid plan: from $19 a month.

What it builds: form-based apps that people add to their home screen "without needing to go through an app store."

Store publishing: not supported.

Code export: not listed.

Getting users: no marketing tools documented.

Watch out for: best for forms, payments and check-ins rather than full apps.

In its own words: Jotform says people can add apps to their home screen "without needing to go through an app store."

Free plan in practice: build an app around 5 forms with up to 100 submissions a month, with Jotform branding.

Publishing, step by step: share the app link; people install it from the browser.

Pitfall: submission limits on the free plan are low for busy events.

Not for: full apps with custom screens, accounts and logic.

Best for: event check-ins, intake forms and field reporting.

11. MIT App Inventor: Best Free Tool for Learning to Build Apps

Free plan: the tool is free.

Cheapest plan that publishes: no plan; you pay Google's US$25 for Google Play and Apple's $99 a year for the App Store.

What it builds: Android apps with drag-and-drop blocks; its official guide also covers building iOS apps and uploading them to the App Store with an Apple Developer account.

Store publishing: you upload and submit the apps yourself.

Code export: projects are saved in App Inventor's own format.

Getting users: no marketing tools documented.

Watch out for: block-based programming is still programming; it is designed for learning.

In its own words: MIT App Inventor's official guide covers building iOS apps and uploading them to the App Store with an Apple Developer account, alongside its Android builds.

Free plan in practice: everything is free, including testing on your phone with its companion app.

Publishing, step by step: build the app file, create your store listings, and upload and submit yourself.

Pitfall: you design every behavior with programming blocks, which takes time to learn.

Not for: founders who want a production app without learning to program.

Best for: students, teachers and anyone learning how apps work.

12. Kodular: Best Free Tool for Android Learners

Free plan: free, with ads shown only in the builder: "We don't insert ads in your app."

Cheapest plan that publishes: the free plan can build apps with up to 5 extensions per project; Premium (€3.99 a month or €40.99 a year) removes limits, and Google's US$25 fee applies.

What Each Free Plan Includes, Builder by Builder

Our Verdict on Each Free Builder

Common Publishing Problems and How to Avoid Them

What Free App Builders Cannot Do

Checklist Before You Upgrade to a Paid Plan

• Superapp or your chosen builder has built your core screens and they work on a phone or simulator.
• Five real people have tried the app and completed the main action.
• You know which plan publishes and how many apps it allows.
• You have an Apple Developer account ($99 a year) and, for Android, a Google Play Console account (US$25 once).
• You have a privacy policy URL.
• You know who submits to the stores: Superapp submits for you; with most builders, you do.
• You know how you will get users: ASO, Apple Ads, a website, creators, or Superapp's Selfdrive on Max.
• You know your exit: whether you can export your code.

Who Should Not Use a Free App Builder?

• Teams with a complex product and developers on staff, who may move faster in Xcode or Android Studio, with Superapp's Xcode export as an option for the iPhone side.
• Apps that need custom hardware integrations or unusual system access, which usually need a developer.
• Anyone who cannot spend at least a paid plan and the store fees, because no builder here publishes for free.

How Do the Free Plans Compare?

What Do You Need to Pay to Publish?

Apple's $99 a year and Google's US$25 one-time fee come on top of any plan. Superapp is the only builder here that prepares the full listing, screenshots and privacy details and submits the app for review for you; Appy Pie's team helps with submission on its plans.

What About AI Web App Builders Like Lovable, Bolt and Base44?

AI web app builders have generous free tiers, but most do not produce mobile apps for the stores:

If you want a phone app in the stores, a web app builder means extra steps, and a wrapped website risks Apple's Guideline 4.2, which asks apps to go "beyond a repackaged website." For a full comparison of AI builders, see our guide to the best AI app builder.

Superapp vs Adalo vs FlutterFlow vs Bubble: The Four Leading Free Builders

Choose Superapp for a native iPhone app built from a description, with submission and marketing handled. Choose Adalo for a database app on both stores, FlutterFlow for Flutter code, and Bubble for a web app with mobile apps.

Positioning at a Glance: What Each Free Builder Is For

Which Free Builder Works on Which Device?

If you need an Apple Watch app from the same project as your iPhone app, Superapp is the only builder here that documents it; for Mac, FlutterFlow also lists desktop apps, built with Flutter rather than native Swift.

Which Free Builder for Which Type of App?

Which Free Builder for Which Kind of Builder?

Pick It or Skip It: One Reason Each

How Do AI, Visual and Block-Based Free Builders Differ?

Describing an app is the fastest way to see your idea on screen, and it uses your free credits efficiently because every request produces real screens. Visual editors give you control of every element but take longer to learn. Blocks teach programming concepts, which is a goal in classrooms and a cost for founders.

What Do the Stores Require Before You Submit?

Whichever builder you use, Apple and Google check the same things. For the App Store, Apple's requirements include:

Apple also lists common issues that hold apps up, including crashes and bugs, placeholder content, incomplete information and inaccurate screenshots. Building a real app on a free plan, rather than a placeholder demo, is the best preparation for review.

What Does Adalo Still Do Well?

Adalo publishes the guide this article responds to, so here is a fair account of what it does well:

• Both stores from one project. Adalo publishes native iOS and Android builds and a web app, which Superapp does not do for Android.
• A built-in database. Records live inside Adalo, so a directory or booking app works without a separate backend.
• A generous test setup. Unlimited test apps on the free plan let you try the app on devices before paying.
• A guided publishing workflow. Adalo walks you through App Store Connect and Google Play Console.

If you need Android and iPhone from one project and want visual control of every screen, Adalo is a sound choice. If you want a native iPhone app built from a description, with submission and marketing handled, Superapp is built for that.

Should You Switch Builders, or Stay?

If you have started on one free builder and are unsure, these are the signs that point each way:

Switching from a visual builder usually means rebuilding the screens, because most builders do not import each other's projects. With Superapp, that rebuild starts from a description, so the time cost is mostly in describing your app clearly.

How Do You Add Android Later If You Start on iPhone?

Starting on iPhone and adding Android later is a common path when most of your early users are on iPhone. With Superapp, your iPhone app is a native Swift Xcode project you can export, and Android needs a separate app built with an Android-capable tool or a developer. If you know from day one that half your users are on Android, starting with a cross-platform builder such as Adalo, FlutterFlow, Bubble or Thunkable avoids a second build. Google Play itself needs a one-time US$25 developer account.

What Did We Leave Out, and Why?

• Web-only internal tool builders, such as Budibase: they build browser apps for teams and do not publish to the app stores, which is what most people searching for a mobile app builder want.
• Developer tools, such as Xcode, Android Studio and code editors: they are free but require programming.
• AI web app builders as ranked picks: Lovable, Bolt, Base44, v0 and Replit are covered in their own section because most of them build web apps rather than store apps.
• Website-to-app converters: they wrap a website in an app shell, which risks Apple's Guideline 4.2.

How Does Superapp Compare With Thunkable, Bravo Studio and Glide?

Superapp vs Thunkable

Choose Superapp for a native iPhone app without learning blocks. Choose Thunkable for a classroom project or a simple app on both stores.

Superapp vs Bravo Studio

Choose Superapp if you want the app built for you from a description. Choose Bravo Studio if you are a designer who wants your Figma file to become the app on both stores.

Superapp vs Glide

Choose Superapp for an app people find in the App Store. Choose Glide for a quick internal app on spreadsheet data.

Which Free Builder Fits Your Kind of App?

A fitness, habit or wellness app

These apps live on the phone every day and benefit from reminders, widgets, Apple Watch and HealthKit. Superapp builds all of these natively. If you also need Android, Adalo, FlutterFlow or Thunkable cover both stores with fewer Apple-specific features.

A booking or directory app for a local business

Lists, detail screens, a booking form and an admin view are the classic database app. Adalo's free plan, with 500 records per app, is built for this pattern, and Superapp builds it natively for iPhone with its built-in backend. Appy Pie's templates suit businesses that match one of its industries.

A restaurant, church or community app

Menus, events, news and push notifications. Superapp builds this for iPhone; Appy Pie offers industry templates; Adalo and Thunkable publish to both stores.

An internal tool for your team

Employees use it on laptops and phones, and it does not need the App Store. Glide (from spreadsheets) and Softr (client portals) are designed for this, and Jotform Apps covers forms and check-ins.

A classroom or learning project

Thunkable and MIT App Inventor are built for teaching, with block-based logic; Kodular suits Android hobbyists.

A designer's portfolio or content app

Bravo Studio turns Figma designs into store apps, and Superapp can use your Figma designs as a reference for a native iPhone app.

How Do the App Store and Google Play Differ for Publishing?

If your audience is mostly on iPhone, starting with the App Store and adding Android later is a common path; if it is split, a cross-platform builder publishes to both from one project.

What Should a Good Free Plan Let You Do?

Use this checklist when you try any builder for free:

• Build your real core screens, not just a template demo.
• Store real data, such as users and the main list your app shows.
• Preview on your phone, not only in the browser.
• Try the AI, if the builder has it, with your own description.
• See the publishing path, including the plan you will need and who submits to the stores.
• Check code export, so you know what happens if you outgrow the builder.
• Check the next step after launch, such as Superapp's Selfdrive on Max, or your own marketing plan.

If a free plan cannot do the first three, you cannot judge the builder before paying.

How Far Does Each Free Plan Get You? A Five-Screen App Test

To make the free plans comparable, picture the same small app on each: a habit tracker with five screens (Today, Add Habit, Habit Detail, Progress, Settings), user accounts and a list of habits stored in a database. Here is how far each free plan takes it, based on each vendor's stated limits:

The pattern is clear: free plans are generous for building and testing, and every path to the stores goes through a paid plan or your own work.

What Hidden Costs Should You Expect?

What Happens to Your App If You Stop Paying?

Worked Example: From a Free Plan to the App Store With Superapp

Start free. Describe the app: "A habit tracker for busy parents with Today, Add Habit, Habit Detail, Progress and Settings screens; each habit has a name, a daily goal and a check-in history; a missed day resets the streak; calm colors and dark mode." Superapp generates the screens, at about one credit per screen.

Refine on the free credits. Ask for one change at a time: a bigger check-in button, a weekly chart on Progress, a reminder at 8 pm. See whether the result is the app you had in mind before you pay anything.

Upgrade when it is ready. Move to Pro at $25 a month for 50 credits a month and automated App Store publishing, and join the Apple Developer Program for $99 a year.

Add what makes it an iPhone app. A Home Screen widget, an Apple Watch app for checking off a habit, and a subscription through in-app purchases.

Publish. Superapp prepares the screenshots, description, privacy details and keywords, and submits the build to Apple for review.

Get users. On Max, Selfdrive runs Apple Ads within your budget, works on App Store keywords, builds a website with SEO content, and briefs creators, with one email each morning about downloads and next steps.

How to Get the Most Out of a Free Plan

Free plans have limits measured in credits, screens, records, projects or AI requests. A few habits make them go much further:

1. Write the app down before you open the builder. One sentence on who it is for, four or five screens, the data each screen shows and the rules. On Superapp, this turns into a single clear first prompt instead of many small corrections.
2. Build the core first. The main action, the screen that shows results, and sign-up. These tell you whether the builder fits; settings and polish can wait.
3. Batch your changes. On AI builders, one clear request for a finished screen is cheaper than ten small edits. On visual builders, finish one screen before starting the next.
4. Use real data. Ten real records reveal more problems than a template's sample data.
5. Test on a phone early. Layouts that work in a browser often feel different on a small screen.
6. Decide what success looks like before paying. For example: "five people can sign up and complete the main action without help."
7. Check the publishing path before you are attached. Know which plan you will need, who submits to the stores, and whether you can export your code.

How Long Does It Take to Go From a Free Plan to a Published App?

The biggest difference is learning time. Visual and block builders reward the time you invest in learning them; AI builders let you skip most of it.

Decide in Seven Questions

Answer in order and stop at the first pick that fits:

1. Is it mainly forms, check-ins or payments? Jotform Apps.
2. Is it an internal tool on a spreadsheet or database? Glide or Softr.
3. Is it a classroom or learning project? Thunkable or MIT App Inventor; Kodular for Android hobby apps.
4. Do you design every screen in Figma? Bravo Studio, or Superapp using your Figma designs as a reference for a native iPhone app.
5. Must it launch on iPhone and Android at the same time? Adalo for a database app, FlutterFlow for Flutter code, Bubble if you also have a web app.
6. Is it an iPhone app, possibly with Apple Watch, iPad or Mac? Superapp.
7. Do you want help getting users after launch? Superapp on Max, with Selfdrive.

Worked Example: A Restaurant App for iPhone, Built on Superapp

The idea. A neighborhood restaurant wants an iPhone app for its regulars: today's menu, a loyalty card that fills up with each visit, table bookings and a push notification for weekly specials.

Free plan. The owner describes the four screens (Menu, Loyalty, Book a Table, Account), the data (menu items with prices and photos, loyalty stamps per customer, bookings by time slot) and the rules (ten stamps earn a free dessert; bookings close an hour before the slot). Superapp generates the screens, about one credit each, and the owner refines the menu layout and the loyalty card in a few requests, checking each change in the preview.

Upgrade and publish. When the app does what the owner wants, they move to Pro, enroll in the Apple Developer Program, and Superapp prepares the screenshots, description, privacy details and keywords and submits the app.

After launch. A Home Screen widget shows the loyalty card, and push notifications announce specials. On Max, Selfdrive can run Apple Ads for local search terms within a set budget and brief local creators to film short videos, with a morning email on downloads.

What the owner learns. Whether regulars install the app, how many bookings come through it, and whether the loyalty card brings people back.

Most free builders stop when the app is live. Getting the first hundred users usually comes from four channels, which you can run yourself or, on Superapp's Max plan, hand to Selfdrive:

Superapp's homepage says Apple Ads can bring installs within days, App Store ranking changes usually take weeks, and website and SEO traffic takes months, and that nothing is guaranteed. Whichever builder you use, measure installs, sign-ups and how many people come back on day two and day seven.

What Happens After Launch: Updates on Each Builder

Every update to a store app goes through the same steps as the first release: a new build, a new version, an upload and a review.

Web app builders have one real advantage here: changes go live without store review. Store apps trade that for discovery in the App Store and Google Play.

Which Free Mobile App Builder Helps You Get Users?

Building and publishing are only the start. Superapp is the only builder in this comparison with a marketing agent that keeps working after launch.

Selfdrive is included in Superapp's Max plan at $100 a month, works with any existing App Store app you own, and sends one email every morning with your downloads, what it did and what it suggests next. Superapp's homepage says Apple Ads can bring installs within days, App Store ranking changes usually take weeks, and website and SEO traffic takes months, and that nothing is guaranteed. With the other builders, you run these channels yourself.

Which Free Mobile App Builder Should You Choose?

Five questions settle it:

1. Do you need the App Store or Google Play? If not, Glide, Softr and Jotform Apps are enough.
2. iPhone only, or both stores? iPhone first points to Superapp; both stores to Adalo, FlutterFlow, Bubble or Thunkable.
3. Do you want to describe the app or assemble it? Superapp builds from a description; the others use visual editors or blocks.
4. Who will submit to the stores? Superapp submits for you; with the others, you finish the listing and submit.
5. How will people find the app? If you have no plan, a builder with a marketing agent saves you the most time.

How Do You Make an App for Free, Then Publish It?

1. Start on a free plan. Build the core screens of your real app, not a demo.
2. Test it on your phone. Most builders let you preview on a device for free.
3. Show it to five people. Fix what confuses them before you pay.
4. Upgrade to the plan that publishes. Superapp Pro at $25 a month for the App Store, or the plan your builder requires.
5. Pay the store fees. Apple's $99 a year, Google's US$25 once.
6. Submit. Superapp prepares and submits the listing; with other builders, you complete it in App Store Connect or Google Play Console.
7. Get users. Run Apple Ads, improve your listing for App Store search, publish a website, or let Superapp's Selfdrive handle it on Max.

What Mistakes Should You Avoid With Free App Builders?

• Assuming free includes publishing. No builder here publishes to the stores on its free plan.
• Building a demo instead of the real app. Use the free plan to build your actual core screens, so you know the builder fits.
• Choosing a web app builder for an App Store app. Glide, Softr and Jotform Apps do not publish to the stores.
• Forgetting the store fees. Apple charges $99 a year; Google charges US$25 once.
• Ignoring code export. Without it, outgrowing the builder means rebuilding.
• Leaving marketing until after launch. Decide early how people will find the app.
• Building a private idea on a public free plan. Thunkable's free projects are public.
• Spending free credits on polish. On Superapp and other AI builders, spend credits on the screens that define your app first.
• Ignoring published-app limits. Adalo's Builder allows 2 published apps and Thunkable's Builder allows 1.
• Skipping the privacy policy. Apple requires a link in App Store Connect and inside the app.

What Are the Myths About Free Mobile App Builders?

Glossary

Where Superapp Fits

As a disclosure, Superapp is our product, so weigh this accordingly. We rank Superapp first because it is the only builder here that turns a description into a native Swift app, submits it to the App Store for you, and then markets it with an AI agent that runs Apple Ads, App Store optimization, SEO and creator campaigns. You can start free with credits, publish on Pro at $25 a month plus Apple's $99 a year, and add Selfdrive on Max at $100 a month. Superapp builds for Apple platforms only; for Android, choose Adalo, FlutterFlow, Bubble, Thunkable or Bravo Studio.
