Can I build a phone app with AI for free? Mother's on the line.
November 12, 2026.
You can build a phone app and test it on your own phone for free. Android makes that easier than iPhone. Putting it in the app stores costs money. Or skip the stores with a web app people add to their home screen.
Which AI builders make phone apps?
- Google AI Studio. It makes native Android apps. You can install one on your own phone over USB. It can send the app to Google Play's internal test track, for up to 100 testers. Its docs don't mention iPhone apps.
- Bolt. Say "mobile app" in your first message, and it builds with Expo, a toolkit for iPhone and Android apps. To publish, you download the code and run Expo's tools yourself.
- Replit. It builds for iPhone and Android, and it can send iPhone apps to Apple. It doesn't publish to Google Play yet.
- Rork. It makes native iPhone and Android apps. It has a free plan to get started. Paid plans run from $20 to $1,800 a month.
- Base44. Its store app is your web app inside a thin native wrapper. Downloading the store files needs the Builder plan, $40 a month billed yearly.
- Lovable. It makes web apps, not native phone apps. Its docs suggest turning your app into one people can add to their home screen.
Can you test it on your own phone for free?
- Android: yes. Install your app over a USB cable with developer options turned on. Or send yourself the app file and allow installs from that source.
- iPhone: yes, with a Mac. A free Apple Account lets you run your own app on up to 3 devices. The app stops working after 7 days, so you install it again.
- Expo Go on iPhone: not anymore for free. Expo's own setup guide now says it needs a paid Apple developer account. Some builders' docs still describe a free scan of a QR code.
Do you need a Mac to make an iPhone app?
Apple's Xcode only runs on a Mac. A cloud build service gets around that. Expo builds iPhone apps on its own Macs.
Expo's free plan includes 15 iPhone builds and 15 Android builds a month, in a slower queue. It also sends the app to both stores. You still need Apple's paid program for an App Store build.
What does it cost to publish?
- Apple App Store. $99 a year. That also covers TestFlight, Apple's beta testing app.
- Google Play. $25 once. A new personal account must test with at least 12 people for 14 days in a row before it can publish.
Can you skip the app stores?
Yes. Build a web app that people can install from the browser. There is no store fee, only hosting.
- Android. Chrome can install it with its own icon.
- iPhone. People tap Share, then Add to Home Screen. Notifications work only after that, on iOS 16.4 or later.
A web app can do less than a native app, most of all on iPhone. Check that the features you need work there.
On Android, Google is starting to require developers to verify who they are, even outside Google Play. Installs over USB are exempt. It started on September 30, 2026, in four countries, and goes worldwide in 2027.
Does the app already exist?
Check before you build. Many business apps already work well on a phone, and plenty are free with public code. Our post on building a business app with AI for free has examples.
Search the directory by the product you would replace, or ask your coding agent:
/mothermachine <what you need>
What we do not cover yet
- We have not built a phone app on each builder. We read their docs and pricing pages.
- Store rules. Apple and Google also review what your app does. Read their guidelines before you submit.
