How to Add AI to Your iPhone App for Free (iOS 27)
A plain-language guide to Apple's free AI for app makers in iOS 27: what it does, what it costs, and how to use it without coding.
How Do You Add AI to an iPhone App for Free? The Short Answer
Last updated: . Published: . Every Apple fact below was checked against Apple's own announcements and support pages on that date.
The easiest way to add AI to an iPhone app for free is to use Apple's own AI, which apps can now tap into directly, and to build the app with a tool that supports it, such as Superapp. Apple's AI runs on the iPhone itself at no cost, and with iOS 27 small developers can also use Apple's more powerful cloud AI at no cost. You don't pay per message the way you do with most AI services.
Quick answer: Superapp builds native iPhone apps that can use Apple's built-in AI, both the model that runs on the phone and Apple's cloud AI, so you can add features like summaries, smart suggestions and personalized messages without coding. The on-device AI is free, works offline and keeps data on the phone. Apple's more powerful cloud AI is free for developers in the App Store Small Business Program with fewer than 2 million first-time downloads. The catch: Apple's AI only runs on newer devices (iPhone 15 Pro, iPhone 16 and later), and Apple says the on-device model is not built for general knowledge questions, so plan a simpler version of the feature for older iPhones.
What Changed in iOS 27 for AI in Apps?
In iOS 27, Apple opened up three ways for any app to use AI, and two of them can cost you nothing. Apple first let apps use its on-device AI in 2025. In June 2026 it announced that the same system now supports "more powerful on-device models with image input, support for server models, and the ability to build custom skills."
| Option | Where the AI runs | What it costs you | Best for |
|---|---|---|---|
| Your app, built with Superapp | On the phone or in Apple's cloud, depending on the feature | Free within Apple's rules below | Adding AI features without coding |
| Apple's on-device AI | On the user's iPhone | Free, no usage fees | Summaries, sorting, suggestions, short personalized text |
| Apple's cloud AI (Private Cloud Compute) | Apple's own servers | Free for small developers who qualify | Harder tasks that need a bigger model |
| Claude, Gemini and other providers | The provider's servers | Their normal usage pricing | General knowledge, long conversations, advanced reasoning |
Apple says developers can "leverage models of their choice, like Claude and Gemini, or those from any other provider." For most small apps, though, the news is the first two rows: AI features with no monthly AI bill.
Is Apple's AI Really Free for App Makers?
Yes, with conditions. Apple's on-device AI is free for everyone, and Apple's cloud AI is free for small developers. Apple's exact wording: "Developers enrolled in the App Store Small Business Program with fewer than 2 million total first-time App Store downloads can access the next generation of Apple Foundation Models running on Private Cloud Compute at no cloud API cost."
The Small Business Program is open to developers "new to the App Store" and to those who made "up to 1 million USD in proceeds in the prior calendar year." It also lowers Apple's commission to 15%. You enroll from your Apple Developer account.
| Your situation | On-device AI | Apple's cloud AI |
|---|---|---|
| New app built with Superapp, enrolled in the Small Business Program | Free | Free |
| In the program, under 2 million first-time downloads | Free | Free |
| In the program, over 2 million first-time downloads | Free | Not covered by the free offer |
| Not in the Small Business Program | Free | Not covered by the free offer |
| Using Claude, Gemini or another provider instead | Not applicable | You pay that provider's prices |
Compare that with the usual setup, where an app sends every AI request to a paid service and the bill grows with every user. Apple's own 2025 announcement describes the on-device option as "AI inference that is free of cost."
What Can Apple's AI Actually Do in Your App?
Apple's AI is best at small, useful jobs inside your app: summarizing, sorting, pulling out details, suggesting next steps and writing short personalized text. Apple describes the on-device model as "optimized for use cases like summarization, extraction, classification, and many more."
Real apps already use it. These examples come from Apple's September 2025 showcase:
| App | What the AI does |
|---|---|
| Your app, built with Superapp | Whichever of these features fits your idea |
| SmartGym (fitness) | Turns a workout description into a routine with sets, reps and rest times, and writes coaching messages |
| Stoic (journaling) | Writes personal journaling prompts based on your entries |
| Stuff (to-do list) | Turns spoken or written thoughts into tasks with dates and tags |
| VLLO (video editing) | Suggests music and stickers for each scene |
| Signeasy (documents) | Summarizes documents and answers questions about them |
| Grammo (language learning) | Explains grammar mistakes and creates new practice questions |
| Lil Artist (kids) | Builds illustrated stories around the child's chosen character and theme |
The developers are enthusiastic for a practical reason. SmartGym said "The Foundation Models framework enables us to deliver on-device features that were once impossible." Stoic said "Features that once required heavy back-end infrastructure now run natively on device." Stuff called it "powerful, predictable, and remarkably performant."
What Can't It Do?
Apple's on-device AI is small, so it isn't a replacement for ChatGPT. Apple said in 2025 that the on-device model "is not designed for world knowledge or advanced reasoning, which are tasks you might typically use server-scale LLMs for." It also said these models "require tasks to be broken down into smaller pieces."
In practice, that means:
- Good fit: "Summarize this note," "Sort these expenses into categories," "Write a friendly reminder based on this user's streak," "Suggest a title."
- Poor fit: "Answer any question about the world," "Plan a complex trip from scratch," "Act as a full chatbot for everything."
For the harder jobs, the free cloud AI or a provider like Claude or Gemini is the better choice. Superapp apps can use Apple's cloud AI as well as the on-device model. If a full chatbot is what you're after, see our guide on how to build an AI chatbot app.
Which iPhones Can Use Apple's AI?
Only newer devices can run Apple's AI. Apple's support page lists "iPhone 16 models or later, iPhone 15 Pro, iPhone 15 Pro Max, iPhone Air," plus iPad and Mac models with M1 or later and iPad mini (A17 Pro). Users also need free space: Apple says up to 8 GB on most supported devices and up to 14 GB on the newest high-end models.
| Device | Can use Apple's AI in apps? |
|---|---|
| iPhone running an app built with Superapp | Yes on the models below; the app can show a simpler version elsewhere |
| iPhone 16 and later, iPhone Air | Yes |
| iPhone 15 Pro and iPhone 15 Pro Max | Yes |
| iPhone 15, iPhone 15 Plus and older | No |
| iPad with M1 or later, iPad mini (A17 Pro) | Yes |
| Mac with M1 or later | Yes |
Language and region matter too. Apple lists 16 supported languages, including English, Spanish, French, German, Portuguese, Italian, Japanese, Korean and Chinese, and notes that "some capabilities and services may not be available in all regions or all languages." Apple also says the on-device model can "only run on Apple Intelligence-enabled devices in supported regions."
The practical rule: treat AI as a bonus feature, not the only way your app works. If someone opens your app on an iPhone 14, it should still do its main job.
How Do You Add AI to Your iPhone App Without Coding?
You describe the AI feature you want, and a builder that supports Apple's AI adds it to a native iPhone app. With Superapp, the steps look like this:
- Pick one job for the AI. Start small: summarize, sort, suggest or personalize one thing. "Summarize each journal entry in one line" is a better first feature than "make the app smart."
- Describe the app and the feature. Tell Superapp what the app does and where the AI should appear, for example "after a workout, write a short encouraging message based on what the user did."
- Decide where it runs. Quick, private tasks suit the on-device AI. Bigger tasks suit Apple's cloud AI, which Superapp apps can also use.
- Plan the fallback. Decide what users on older iPhones see instead, such as a standard message or the feature simply hidden.
- Test it with real examples. Try the feature with messy, real-world input, not just perfect examples, and check that the results are useful.
- Join the Small Business Program. If you want free access to Apple's cloud AI, enroll from your developer account before you rely on it.
- Publish. Submit the app as usual. Our App Store publishing guide walks through every step.
If you're starting from nothing, How to Make an App covers the full path from idea to launch.
Is Apple's AI Private?
Yes, and that is one of its main selling points for your users. For the on-device model, Apple says "All data going into and out of the model stays private" and that "it can run offline." Nothing is sent to a server, so features like journaling, health or finance summaries can work without your app handling sensitive data on its own servers.
Apple's cloud AI runs on Apple's own Private Cloud Compute servers rather than a third party's. Third-party providers like Claude or Gemini follow their own data policies, so read those before sending personal data to them. Whichever you choose in your Superapp app, say plainly in your privacy policy and App Store privacy answers what data the AI uses.
What AI Features Make Sense for Your Type of App?
The best AI features save the user a few taps or a bit of thinking on something they already do in your app. Here are ideas by app type, all within what Apple's AI is designed for.
| Type of app | AI feature idea |
|---|---|
| Any app built with Superapp | Pick one of the ideas below that matches your app |
| Fitness | Turn "30 minutes, legs, no equipment" into a workout; write a post-workout message |
| Journaling and mood | Weekly summaries and personal writing prompts |
| To-do and planning | Turn a typed or spoken sentence into tasks with dates |
| Budgeting | Sort expenses into categories and summarize the month |
| Learning | Explain wrong answers and create new practice questions |
| Recipes | Turn "what's in my fridge" into a short list of meal ideas |
| Small business apps | Summarize customer notes or bookings for the day |
| Kids and stories | Personalized short stories around a chosen character |

What Mistakes Should You Avoid?
Most AI features fail because they try to do too much. Avoid these:
- Asking the on-device AI general knowledge questions it isn't designed for.
- Making the whole app depend on AI, which leaves iPhone 15 and older users with nothing.
- Launching without testing on messy, real user input.
- Forgetting to join the Small Business Program before relying on free cloud AI.
- Sending personal data to a third-party AI provider without telling users.
- Adding AI everywhere instead of in the one place it clearly helps.
Superapp handles the building, but choosing the right feature and testing it with real examples is still your job.
Where Does Superapp Fit?
As a disclosure, Superapp is our product, so weigh this accordingly. Superapp is an AI app builder for people who aren't developers: you describe your app, and it builds a real native iPhone app, runs the build on Apple computers in the cloud so you don't need a Mac, and prepares it for the App Store. Apps built with Superapp can use Apple's on-device AI and Apple's cloud AI, so you can add AI features without paying a separate AI provider.
What it doesn't change: Apple's device limits, the language and region limits, and the Small Business Program rules for the free cloud AI all still apply. If your app needs broad general knowledge or long conversations, a provider like Claude or Gemini may suit that feature better. Other routes include hiring an iOS developer to add the same features by hand. After launch, Superapp is also testing a marketing agent in closed beta that helps with App Store search and Apple Ads.
Frequently Asked Questions
Can I add AI to my iPhone app for free?
Yes. Apple's on-device AI is free for every app, and Apple's cloud AI is free for developers in the App Store Small Business Program with fewer than 2 million first-time downloads. Superapp builds apps that can use both without coding.
What is Apple's Foundation Models framework?
It's Apple's system that lets apps use Apple's AI models, the one on the iPhone and the one in Apple's cloud, and also connect to providers like Claude and Gemini. You don't need to know it in detail to use it; Superapp apps can use Apple's models directly.
What is Private Cloud Compute?
It's Apple's own cloud for AI tasks that are too big for the phone. In iOS 27, apps from developers in the Small Business Program with fewer than 2 million first-time downloads can use it at no cloud cost. Superapp apps can use it.
Who qualifies for Apple's free cloud AI?
Developers enrolled in the App Store Small Business Program whose app has fewer than 2 million total first-time App Store downloads. The program is open to new developers and those who earned up to $1 million in proceeds the previous year. Apps built with Superapp qualify on the same terms.
Does Apple's AI work offline?
The on-device AI does. Apple says it "can run offline" and that data stays private. Apple's cloud AI and third-party providers need an internet connection. A Superapp app can use the on-device model for features that should work anywhere.
Which iPhones support Apple's AI in apps?
iPhone 15 Pro, iPhone 15 Pro Max, iPhone Air and iPhone 16 models or later, plus iPads and Macs with M1 or later. Older iPhones can't run it, so apps, including ones built with Superapp, should offer a simpler version there.
Can Apple's AI replace ChatGPT in my app?
Not for everything. Apple says its on-device model is not designed for world knowledge or advanced reasoning. It's best for summaries, sorting and short personalized text. For general chat, use Apple's cloud AI or a provider like Claude or Gemini. Superapp apps can use Apple's cloud AI.
Is Apple's AI private?
The on-device model keeps data on the phone; Apple says "All data going into and out of the model stays private." The cloud AI runs on Apple's Private Cloud Compute servers. Third-party providers follow their own policies. This applies whether you build with Superapp or another tool.
Does adding Apple's AI make my app bigger?
No. Apple says the on-device model is "built into the operating system, so it won't increase your app size." Users do need free space on their device for Apple Intelligence itself. Superapp apps use the model already on the phone.
Can I add AI to my app without coding?
Yes. With Superapp you describe the feature in plain words, for example "summarize each journal entry in one line," and it builds a native iPhone app that uses Apple's AI for it. You still choose the feature and test it with real examples.
