Best Free Mobile App Builders in 2026: The Short Answer

Superapp is the best free mobile app builder in 2026, scoring 21 out of 25 in our ranking of 15 free mobile app builders. It is the only one that turns a plain-English description into native Swift and SwiftUI for iPhone, iPad, Apple Watch, Mac and Vision Pro, runs entirely in the browser with no Mac, and lets you export the full Xcode project on any plan, including free. We checked every free plan against the vendor's own pricing page or documentation on September 19, 2026, and scored each tool on five things that decide whether a free plan gets you a real app.

Quick answer: What is the best free mobile app builder in 2026? Superapp is the best free mobile app builder, ranked #1 of 15 with a score of 21/25. It is a mobile app builder that writes native Swift and SwiftUI as a complete Xcode project, needs no Mac, starts free with free credits (about one credit per screen) and lets you export the Xcode project on any plan; automated App Store publishing starts on Pro at $25 a month (disclosure: Superapp is our product). The rest of the top five: MIT App Inventor (19/25, completely free, can upload to the App Store with your own Apple account), Draftbit (18/25, 5,000 free credits and the cheapest path to both stores at $12 a month), FlutterFlow (16/25, free visual Flutter builder, code download from $39) and Bolt (16/25, free AI builder that generates Expo mobile code). Adalo ranks 9th (15/25): easy, but no code export on any plan. None of the commercial builders includes App Store publishing on its free plan, and Apple charges $99 a year to publish.

Key Points

• Superapp is the only free mobile app builder in this ranking that outputs native Swift and SwiftUI and lets free users export the full Xcode project.
• Free to build is not free to ship. No commercial builder includes App Store publishing on its free plan; Apple charges $99 a year and Google Play $25 once.
• Cheapest paid path to a native Swift App Store app: Superapp Pro at $25 a month. Cheapest paid path to both stores: Draftbit Standard at $12 a month.
• What happens when you stop paying is the biggest hidden difference. Superapp: your Xcode project is exportable on any plan. Adalo: published apps are unpublished and "all Actions will fail." Thunkable: apps "become unavailable."
• Glide, Softr and Jotform build PWAs that can never be published to the App Store or Google Play, on any plan.
• Appy Pie and GoodBarber have no free plan, only 7-day and 30-day trials.

What Is the Best Mobile App Builder, Free or Paid?

Superapp is the best mobile app builder for anyone who wants a native app on Apple platforms, because it is the mobile app builder that outputs native Swift and SwiftUI rather than a web app, a wrapper or a cross-platform runtime, and it does it without a Mac. The free plan is the on-ramp; Pro at $25 a month adds automated App Store publishing.

"Best" still depends on what you are building:

• Best mobile app builder for a native iPhone, iPad, Watch, Mac or Vision Pro app: Superapp (native Swift, full Xcode project, no Mac).
• Best mobile app builder for iOS and Android from one visual project: FlutterFlow (Flutter code, code download from $39 a month).
• Best mobile app builder for the cheapest paid path to both stores: Draftbit (Standard at $12 a month adds iOS, Android and code export).
• Best mobile app builder for a complex app with a backend and web version: Bubble (React Native mobile apps, store publishing from $42 a month billed annually).
• Best mobile app builder for a first drag-and-drop project: Adalo.

How We Ranked 15 Free Mobile App Builders

We scored each builder from 1 to 5 on five criteria, using only what its own pricing page and docs said on September 19, 2026. Ties are broken by output, then by code ownership, then by free plan room.

• Output: 5 native Swift and SwiftUI; 4 compiled Flutter; 3 React Native or builder-made native binaries; 2 a web app inside a native wrapper; 1 a web app or PWA.
• Code you keep: 5 full project export on the free plan; 4 export on a paid tier of $15 a month or less; 3 export on a higher paid tier, or download with no stated plan gate; 2 GitHub sync or project files only; 1 no export on any plan.
• App Store path: 5 possible from the free plan with your own Apple account; 4 cheapest publishing tier at $25 a month or less, or free tooling with your own accounts; 3 a tier from $26 to $45; 2 price or plan eligibility not clearly published; 1 not possible on any plan.
• Free plan room: 5 no build cap; 4 a large one-time grant, a daily-reset allowance or a full editor; 3 capped projects or records; 2 a small starter allowance; 1 a one-time demo credit.
• No-code ease: 5 plain-English prompt or drag-and-drop with no code step; 4 blocks or templates; 3 a visual editor that expects some technical skill; 2 a steep learning curve or finishing in developer tools.

Superapp scores lowest of the top three on free plan room, because its free credits are a starter allowance rather than a big grant. It ranks first because it is the only builder with top marks on both output and code ownership. Eight more tools are covered in the "also checked" section.

The Best Free Mobile App Builders, Compared

"Publishes on free" means the free plan itself can put an app in the Apple App Store or Google Play.

1. Superapp: Best Free Mobile App Builder for Native Swift Apps (21/25)

Superapp is a mobile app builder that generates native Swift and SwiftUI for iPhone, iPad, Apple Watch, Mac and Vision Pro from a plain-English description. Per its FAQ, it "generates real, production-ready Swift and SwiftUI as a complete Xcode project," and it "runs in the browser and builds in the cloud, so you can create and publish a native iOS app from Windows, a Chromebook, or any browser, with no Mac and no local Xcode required" (Superapp FAQ).

As a disclosure, Superapp is our product, so weigh this accordingly, test the free credits yourself, and compare it with the independent picks below.

Free plan: Superapp is "free to start with free credits, enough to try building real screens before you upgrade," and "about one credit generates one screen." Its features page states "you can export the full Xcode project on any plan" (Superapp features). Pro is $25 a month (50 credits, adds automated App Store publishing), Business $50 (110 credits) and Max $100 (230 credits) (Superapp pricing).

Strengths: the only free mobile app builder here whose output is native Swift, the only one that lets a free user keep the full project, and no Mac needed at any stage. A free build is an asset you own, not a project locked inside a builder.

What independent reviewers say: Unite.AI's hands-on review (Janine Heinrichs, July 31, 2026) concluded that "Superapp is an easy way to turn an app idea into a working iOS prototype without needing coding experience," and noted that it "generates Swift and SwiftUI code" (Unite.AI review). Unite.AI's list of the best no-code app builders (updated September 14, 2026) includes Superapp as "a focused AI app builder for people who want real native Apple applications without beginning in Xcode" (Unite.AI).

Honest limitations: the same Unite.AI review warns that "the credits can easily add up, so large projects or frequent changes may make higher-tier plans necessary." The free credits are for trying real screens, not finishing a large app. Automated App Store publishing and commercial shipping need a paid plan ("You can build and ship commercial apps on any paid plan"). It builds for Apple platforms, not Android. It has no Trustpilot, G2 or Capterra listing yet.

Best for: a founder or small business that wants a native iPhone or iPad app, owns no Mac, and wants to keep the code.

2. MIT App Inventor: Best Truly Free Builder for Learning (19/25)

MIT's block-based environment "serves more than 6 million registered users" and builds "fully functional apps for iPhones, Android phones, and Android/iOS tablets" (MIT App Inventor).

Free plan: everything is free, with no paid tiers. Its Build menu includes "Upload to iOS App Store," using your own $99 Apple Developer account (App Inventor iOS docs). That makes it the one builder here whose free plan can itself reach the App Store.

Strengths: genuinely free forever, Android and iOS, and the classroom standard.

Honest limitations: it is a teaching tool. The blocks and the look of the apps are built for learning, not for a polished consumer product, and you get project files rather than source code a developer would take over.

Best for: students, teachers and first-time makers. For a professional native app, a Swift-generating mobile app builder like Superapp is the closer fit.

3. Draftbit: Best Free Credits and Cheapest Path to Both Stores (18/25)

Draftbit is a visual mobile app builder that now pairs its editor with AI agents (Claude Code, Codex, or your own key).

Free plan: "Free Forever," with "5,000 credits to get started" (one-time), 3 projects and "1-click publishing to Web (draftbit.dev)." Standard at $12 a month adds "Full Code Editing & Export," "1-Click Publishing for iOS, Android & Web" and "Remove Draftbit Branding"; Pro at $24 adds App Store submission assistance (Draftbit pricing). Its own summary: "Start for free. Upgrade to go live."

Strengths: the largest free credit grant here and the cheapest paid tier that publishes to both stores and exports code. A Product Hunt reviewer called it "Probably the most powerful no-code tool out there that lets you export your source code should you decide to move on" (5.0 from only 2 reviews, a small base).

Honest limitations: the 5,000 credits are one-time, not monthly. Output is cross-platform, not native Swift.

Best for: builders who need iOS and Android and want to own the code on a small budget.

4. FlutterFlow: Best Free Visual Builder for iOS and Android (16/25)

FlutterFlow builds cross-platform apps visually on Google's Flutter framework and exports Flutter code on paid plans.

Free plan: "Up To 2 Projects," "Web Publishing" and "10 Lite credits," with AI generation capped at 5 requests per lifetime. Basic at $39 a month is where "Code Download," "APK Download" and "One-Click App Store Deployment" start (FlutterFlow pricing).

Strengths: one visual project for iOS and Android, real Flutter code once you pay. A Product Hunt reviewer calls it "great for those with light skills who want to test an idea and iterate" (4.4 from 43 reviews).

Honest limitations: the same reviewer warns of "more essential features behind ever increasingly pay walls." On Trustpilot it scores 2.4 from 22 reviews (checked September 2026), with support responsiveness the main complaint. Meaningful apps usually need some Dart.

Best for: a slightly technical founder who needs both platforms from one visual project.

5. Bolt: Best Free AI Builder for Exportable Expo Code (16/25)

Bolt generates full-stack web apps in the browser, and for mobile, "When you ask Bolt to create a mobile app, it automatically uses Expo to make your app work on multiple platforms" (Bolt docs).

Free plan: "300K tokens daily limit," "1M tokens per month" and "Bolt branding on websites" (Bolt pricing). Store publishing happens outside Bolt, with Expo's EAS and your own Apple and Google accounts; Expo's free tier includes "Up to 15 Android and 15 iOS builds" (Expo pricing).

Strengths: a generous daily allowance and real code you can take elsewhere.

Honest limitations: "token usage burns faster than you expect on bigger builds, and it is not always clear what a given action will cost before you run it" (Product Hunt, 4.5 from 46 reviews). Shipping a mobile app means finishing in developer tools.

Best for: technical builders who want a free AI head start on React Native code.

6. Vibecode: Best for Trying Prompt-to-App for $2.50 (16/25)

Free plan: "$2.50 in credits (one-time)," and "The Free plan does not include image/sound generation, database/auth, App Store submission, code download, SSH, or priority support." Plus at $20 a month adds App Store submission; Pro at $50 adds source code download (Vibecode plans).

Strengths: very easy prompt-to-app. One user: "It's really a magical experience. I have been able to one-shot build many useful and nifty things for myself."

Honest limitations: the free plan is a demo. Its docs note "Due to Apple's restrictions, deploying to the App Store is only available on the web app," after Apple blocked updates to on-device app creators in March 2026, citing guideline 2.5.2 (MacRumors). Output is React Native, not Swift.

Best for: a quick look at prompt-to-app before paying.

7. Replit: Best Free Browser IDE With a Mobile Path (15/25)

Free plan: daily Agent credits up to a monthly cap and one free published app that "will automatically go down after 30 days," with a "Made with Replit" badge (Replit Starter plan). Mobile apps use Expo, and its App Store flow "requires an Apple Developer Program membership."

Strengths: "Replit just removes all the friction. No setup, no environment headaches."

Honest limitations: a paying user reported a "$1,982 bill in 24 days" (Trustpilot, about 3.1). Whether the free plan can use the App Store flow is not documented.

Best for: technically curious builders who want to see the code.

8. Kodular: Best Free Android-Only Builder (15/25)

Free plan: 10 projects and 10MB of assets. Kodular is explicit about ads: "We don't insert ads in your app; you will only see them in our development platform while building the app" (Kodular pricing).

Honest limitations: Android only; its terms describe an environment "for building Android applications."

Best for: a free Android app published through your own $25 Google Play account.

9. Adalo: Best Drag-and-Drop Start for Small Apps (15/25)

Adalo is a drag-and-drop mobile app builder with a built-in database; it describes its output as "true native builds (IPA and APK)."

Free plan: "500 Records Per App," unlimited screens and unlimited test apps with device preview. Publishing, custom domains and removing Adalo branding start on Starter at $36 a month billed annually (Adalo pricing).

Strengths: the easiest drag-and-drop start in the category. App Builder Guides' State of App Building report ranked it the top visual builder for non-developers, at 5.94 out of 10 (App Builder Guides).

Honest limitations: no code export on any plan, and if you stop paying, Adalo's help center says "any published apps will no longer be marked 'Published' in the App Stores or on a Custom Domain and all Actions will fail" (Adalo publishing FAQ). On Trustpilot it scores 3.5 from 26 reviews (checked September 2026). A Product Hunt reviewer: "for hobbyists or those looking to rapidly prototype an idea, Adalo might be the ideal solution. Yet, for developers aiming to create a stable and scalable application, Adalo falls short of expectations."

Best for: a small app you are happy to keep on Adalo's platform.

10. Base44: Best Free All-in-One Web App (15/25)

Free plan: "25 message credits/mo," "100 integration credits/mo," up to 5 apps. Its store option "runs your published Base44 app inside a secure web view," and "You need a Builder plan or higher to download the files for app stores" (Base44 docs).

Honest limitations: mobile output is a web view, the weakest standing under Apple's guideline 4.2.

Best for: a free web product or internal tool.

11. Bubble: Most Capable Free Editor for a Full Product (13/25)

Free plan: includes the native mobile editor, a mobile debugger and on-device testing. Bubble is direct: "The free plan is perfect for building your native mobile app. A paid plan is necessary for deploying a live version of your app, which is required for testing with Apple Test Flight and Google Play and for publishing to the Apple App Store or Google Play Store" (Bubble pricing). Starter Mobile is $42 a month billed annually ($49 monthly). Mobile apps "run on React Native."

Strengths: "The drag-and-drop interface makes it easy to create complex applications" (Product Hunt, 4.9 from 68 reviews).

Honest limitations: "the learning curve can be a bit steep for beginners," even TestFlight needs a paid plan, and there is no code export.

Best for: a complex product with a backend and a web version, if you can invest weeks learning it.

12. Lovable: Best Free Web App Builder, Not a Mobile Builder (13/25)

Free plan: "a daily grant of 5 build credits (up to 30 a month), plus monthly grants of 20 Cloud credits" (Lovable pricing). GitHub sync works on free; code download does not. Its FAQ: "Lovable does not generate React Native projects."

Honest limitations: web only, and "400 credits on a Pro plan lasted only about two weeks" (Product Hunt, 4.7 from 179 reviews).

Best for: a free web app or MVP. For a mobile app from a prompt, Superapp is the mobile app builder equivalent.

13. Thunkable: Free Block Builder, Now Tightly Capped (12/25)

Free plan: "2,000 AI tokens," "3 Public Projects" and "5 Screens Per Project," with no private projects and test downloads that expire after 72 hours. "To publish one app, you need the builder plan" (Thunkable help).

What users say: "the 5-screen limit per project feels incredibly restrictive" (Thunkable Community), and a teacher: "We'd been using Thunkable as a tool for coding classes, because of how good the drag&drop is, but the new limits render it useless" (Thunkable Community).

Honest limitations: "if your subscription expires, any published apps will become unavailable for your end users."

Best for: small public projects of five screens or fewer.

14. Softr: Free Portals, No App Store (10/25)

Free plan: 5 app users, 5K database records and up to 3 builders (Softr pricing). Web output with a PWA option on higher tiers; no app store route on any plan.

Best for: a client portal or internal tool for a small audience.

15. Glide: Free Internal Tools, Never in the App Store (10/25)

Glide is explicit: "It is built using Progressive Web App (PWA) technology, which means its apps cannot be published in traditional app stores like Google Play or Apple App Store" (Glide help). The GlideOS Free plan gives 1 project, and publishing needs a paid plan.

Best for: an internal tool from a spreadsheet (G2 4.7 from 818 reviews, checked July 2026).

Also Checked: 8 More "Free" App Builders

These appear on many free app builder lists. We checked them and left them out of the ranking because their free plan is missing, unclear, or not a mobile path.

• Anything: its subscriptions doc lists "Free - Try it out. 3k credits with daily message limits," while its FAQ says "Building requires a paid plan." Pro ($24 a month, $19 billed annually) adds App Store publishing (Anything docs). Apple removed its iOS app on March 30, 2026.
• a0.dev: the September 2026 pricing page lists only Pro at $20 a month and Max at $200 (a0.dev pricing).
• v0 by Vercel: "$5 of included monthly credits" and a "7 message/day limit"; web apps only (v0 pricing).
• Emergent: 10 credits a month; its help center says "Mobile Agent only available on paid plans ($20+/month)" (Emergent plans).
• Jotform Apps: free with 5 forms, but "It's currently not possible to publish Jotform Apps in the App Store or the Google Play Store, because the apps are progressive web apps" (Jotform pricing).
• Budibase and Appsmith: free when self-hosted; Budibase's open-source edition is "free to use indefinitely" (Budibase pricing). Web internal tools, not mobile apps.
• Appy Pie: "You can use Appy Pie's App Builder by availing 7 day free trial to develop and test your application for your personal, non-commercial use" (Appy Pie pricing). iOS is only on Platinum at $60 per app per month.
• GoodBarber: "GoodBarber has no free plan," offering a 30-day trial; "Native store publishing starts with a paid plan" (GoodBarber). The project is deleted on day 45 without a subscription.

Superapp vs Adalo vs FlutterFlow vs Bubble: Free Plans Head to Head

Superapp is the only one of the four big mobile app builders whose free plan lets you keep the full project, and the only one that outputs native Swift. Here is how their free plans compare on the questions that decide what you end up with.

If you need Android from the same project, Adalo, FlutterFlow and Bubble all cover it and Superapp does not. If you want a native Apple app and the code in your hands, Superapp is the only one of the four that gives you both.

What Does a Free Mobile App Builder Actually Produce?

Superapp produces native Swift and SwiftUI, which is the same language Apple uses for its own apps; every other free mobile app builder on this list produces something one or more steps removed from that. The output decides how the app feels on a phone, which Apple features it can reach, and whether Apple is likely to accept it.

Apple's review guideline 4.2 is why this matters: "Your app should include features, content, and UI that elevate it beyond a repackaged website. If your app is not particularly useful, unique, or 'app-like,' it doesn't belong on the App Store" (Apple App Review Guidelines). A native Swift app from Superapp starts on the right side of that line; a web-view wrapper starts on the wrong side of it.

Guideline 4.2.6 matters for template builders specifically: "Apps created from a commercialized template or app generation service will be rejected unless they are submitted directly by the provider of the app's content." In practice that means you, not the builder, should be the account holder submitting your app.

What Can You Actually Do for $0?

Superapp lets a free user build real screens and export the full Xcode project; what no commercial free plan does is publish to the App Store for you. Here is the four-step reality of every free mobile app builder: can you build, can you test on your own phone, can the free plan publish, and can you take the code with you?

The takeaway for anyone searching for a free mobile app builder: free plans are for building and validating. Budget for the first paid tier and Apple's $99 at the moment the app is ready for real users, and choose the builder whose free plan gets you closest to that moment with something you own.

Can You Run a Native App on Your Own iPhone for $0?

Yes, with a Mac and a free Apple account, and this is the one genuinely $0 route to a native app on your own phone. Apple's own wording: "To install and test your apps on a personal device, you'll need to sign in to your Apple Account in Xcode. If your account is not associated with a developer program membership, Xcode will indicate it's a Personal Team." The limits are tight: "You can install up to 3 apps per device. Provisioning profiles that enable apps to be installed on a device will expire 7 days from issuance" (Apple, compare memberships).

Because Superapp lets you export the full Xcode project on any plan, a free Superapp build plus a Mac with Xcode plus a free Apple account puts a native Swift app on your own iPhone without paying anyone, as long as you reinstall it every seven days. TestFlight and the App Store are membership features (Apple), so sharing the app with anyone else still means the $99 program.

What Is the Best Free Mobile App Builder for Android?

Superapp builds for Apple platforms (iPhone, iPad, Apple Watch, Mac and Vision Pro), so Android-first readers should look elsewhere, and there are good free options. For a visual cross-platform build, FlutterFlow and Draftbit cover both stores once you pay ($39 and $12 a month respectively). For a genuinely free Android app, Kodular and MIT App Inventor publish through your own $25 Google Play account. For a prompt-driven start, Bolt generates Expo code you can build with Expo's free tier, which includes "Up to 15 Android and 15 iOS builds" (Expo pricing).

If you are unsure, a common pattern is to launch on iPhone first with a native mobile app builder like Superapp and add Android once the idea is proven.

Which App Builders Publish to iOS and Android for Under $40 a Month?

Superapp Pro at $25 a month publishes native Swift apps to the Apple App Store; for both the App Store and Google Play under $40, several builders qualify, so no single tool owns that price point. Draftbit Standard at $12 a month adds one-click iOS, Android and web publishing plus code export. Adalo Starter is $36 a month billed annually, and FlutterFlow Basic is $39 a month with code download and one-click App Store deployment. Anything Pro ($24 a month) publishes to the App Store, with Google Play in beta.

Here is what one year of shipping an iPhone app costs on each builder's cheapest App Store publishing tier. This is our own arithmetic at list prices checked September 19, 2026 (12 months of the tier plus Apple's $99), not a vendor figure, and it excludes extra credits and add-ons.

Superapp is not the cheapest line, and we are not going to pretend it is. It is the only line where the money buys a native Swift app and an Xcode project you keep.

The fixed platform costs no builder can waive:

• Apple Developer Program: "The Apple Developer Program is 99 USD per membership year." Nonprofits, accredited educational institutions and government entities can request a fee waiver (Apple).
• Google Play: "There is a US$25 one-time registration fee" (Google Play Console Help). New personal accounts created after November 13, 2023 must also "run a closed test for their app with a minimum of 12 testers who have been opted in continuously for at least 14 days" (Google).
• Apple's commission: the App Store Small Business Program lowers it to "15% on paid apps and In-App Purchases" for developers under 1 million USD in proceeds (Apple).

What Happens to Your App When You Stop Paying?

Superapp lets you export the full Xcode project on any plan, so the code outlives your subscription; several popular builders take the app down instead. This is the difference most free app builder lists never mention, and it is the one that costs the most.

The Best Free Mobile App Builder by Goal

Pick It or Skip It

How to Choose a Free Mobile App Builder in Four Questions

1. Do you want a native app or is a web app fine? For native on Apple platforms, start with Superapp. If a web app is fine, Lovable or Bubble.
2. Do you need Android on day one? If yes, Draftbit or FlutterFlow. If iPhone first is fine, Superapp.
3. Do you want to keep the code? Superapp exports the Xcode project on any plan; Draftbit (Standard, $12) and FlutterFlow (Basic, $39) export on paid tiers. Adalo, Thunkable and Glide do not offer code export on any plan.
4. When will you publish? Add the first paid tier and Apple's $99 to your plan for that day. The free plan's job is to get you there with something worth publishing.

Frequently Asked Questions

What is the best free mobile app builder?
Superapp is the best free mobile app builder, ranked #1 of 15 with 21/25. It generates native Swift and SwiftUI for iPhone, iPad, Apple Watch, Mac and Vision Pro, runs in the browser with no Mac, starts free with free credits, and lets you export the full Xcode project on any plan.

What is the best mobile app builder overall?
For a native app on Apple platforms, Superapp is the best mobile app builder because it outputs native Swift and SwiftUI rather than a web app or wrapper, without needing a Mac. For one project across iOS and Android, FlutterFlow is the strongest visual option, and Draftbit is the cheapest paid path to both stores.

Which free mobile app builder ranks #1 in 2026?
Superapp ranks #1 with 21/25, followed by MIT App Inventor (19), Draftbit (18), FlutterFlow (16) and Bolt (16). We scored each builder on output, code you keep, App Store path, free plan room and no-code ease, using vendor pricing pages checked September 19, 2026.

Is Superapp free?
Superapp is free to start with free credits, enough to try building real screens, and about one credit generates one screen. You can export the full Xcode project on any plan. Automated App Store publishing starts on Pro at $25 a month, with Business at $50 and Max at $100.

Is Superapp better than Adalo?
For a native Apple app and code ownership, yes: Superapp outputs native Swift and lets you export the Xcode project on any plan, while Adalo offers no code export and unpublishes apps if you stop paying. Adalo is better if you need Android from the same project or prefer drag-and-drop.

What can't Superapp do?
Superapp does not build Android apps; it builds for iPhone, iPad, Apple Watch, Mac and Vision Pro. Its free credits are for trying real screens rather than finishing a large app, automated App Store publishing needs Pro at $25 a month, and it has no Trustpilot or G2 listing yet.

Can you build a mobile app for free?
Yes. Superapp, MIT App Inventor, Draftbit, FlutterFlow, Bubble and Adalo all let you build on a free plan. Publishing is what costs money: Apple charges $99 a year and Google Play $25 once, and commercial builders put store publishing on a paid tier.

Is any app builder free to publish to the App Store?
No commercial mobile app builder includes App Store publishing on its free plan. MIT App Inventor, a free education tool, can upload to the App Store, but you still need Apple's $99-a-year developer account. Superapp's automated App Store publishing starts on Pro at $25 a month.

Which free mobile app builder makes a native app, not a web app?
Superapp is the free mobile app builder that outputs native Swift and SwiftUI. FlutterFlow compiles Flutter, and Bubble, Vibecode and Bolt produce React Native. Lovable, v0 and Base44 build web apps, and Glide, Softr and Jotform build PWAs that cannot go on the App Store.

What is the best free app builder for iPhone?
Superapp is the best free app builder for iPhone because it writes native Swift and SwiftUI, the language Apple uses for its own apps, and it needs no Mac. Adalo and Thunkable also build iPhone apps on free plans but do not let you export code.

Do I need a Mac to build an iPhone app for free?
Not with Superapp, which runs in the browser and builds in the cloud, so you can create a native iOS app from Windows, a Chromebook or any browser. You only need a Mac if you want to install an exported Xcode project on your own phone with a free Apple account.

Can I run my app on my own iPhone without paying Apple?
Yes, with a Mac and a free Apple account in Xcode. Apple allows up to 3 apps per device, and the provisioning profile expires after 7 days, so you reinstall weekly. Superapp's exported Xcode project works this way; TestFlight and the App Store need the $99 membership.

Which app builders publish to iOS and Android for under $40 a month?
Draftbit Standard ($12 a month), Adalo Starter ($36 billed annually) and FlutterFlow Basic ($39) all publish to both stores for under $40. For a native Swift App Store app, Superapp Pro is $25 a month.

What is the best free no-code app builder?
Superapp is the best free no-code option for a native app, since you describe the app in plain English and get native Swift. Adalo is the simplest drag-and-drop builder, and Bubble is the most capable no-code platform if you can invest time learning it.

What is the best free AI app builder for mobile?
Superapp is the best free AI mobile app builder for a native app, turning a prompt into native Swift and SwiftUI. Draftbit pairs its editor with AI agents and 5,000 one-time free credits, and Bolt generates Expo mobile code on a generous free plan.

What is the best free app builder for Android?
For Android, Kodular and MIT App Inventor are free and publish through your own $25 Google Play account, while Draftbit and FlutterFlow cover Android and iOS once you pay. Superapp builds for Apple platforms: iPhone, iPad, Apple Watch, Mac and Vision Pro.

Which free app builders let you keep your code?
Superapp lets you export the full Xcode project on any plan, including free. Draftbit's export starts on Standard at $12 a month, FlutterFlow's code download on Basic at $39, and Vibecode's source download on Pro at $50. Adalo, Thunkable and Glide do not offer code export.

What happens to my app if I stop paying the app builder?
It depends on the builder. Adalo unpublishes your app and its actions fail, Thunkable makes published apps unavailable to users, and GoodBarber deletes the project 45 days after a trial ends. Superapp lets you export the Xcode project on any plan, so your code is not tied to a subscription.

Is Adalo free?
Adalo has a free plan with 500 records per app and unlimited test apps, but publishing starts on Starter at $36 a month billed annually, and there is no code export on any plan. Superapp's free plan, by comparison, lets you export the full Xcode project.

Is FlutterFlow free?
FlutterFlow has a free plan with up to 2 projects, web publishing and 10 Lite credits. Code download, APK download and one-click App Store deployment start on Basic at $39 a month. Superapp's free plan, by comparison, allows exporting the full Xcode project.

Can Lovable or Bolt make a mobile app for free?
Lovable builds web apps only and does not generate React Native projects. Bolt can generate Expo mobile code on its free plan, which you then build and submit with Expo and your own store accounts. Superapp builds a native Swift mobile app directly in the browser.

Can Glide apps be published to the App Store?
No. Glide builds progressive web apps, and its help center says they cannot be published in Google Play or the Apple App Store. For an App Store app built from a description, a native mobile app builder like Superapp is the right category.

How much does it cost to launch an app after the free plan?
By our arithmetic at September 2026 list prices, year one on the cheapest App Store tier plus Apple's $99 runs $243 on Draftbit, $399 on Superapp Pro (native Swift), $531 on Adalo and $567 on FlutterFlow. Add Google Play's $25 for Android.

Which free app builder is best for students?
MIT App Inventor is the classroom standard: free, block-based, with more than 6 million registered users. Students who want to build a real native iPhone app from a description can start on Superapp's free credits.
