Android App Builder: Create an Android App with AI

To create an Android app with AI in Mythex, describe the app in chat, publish it, then ask for the Android build. On the Pro plan, Mythex builds it on its own machines and either hands you the file for Google Play or sends it to your app's internal testing track.

Who it's for

Businesses and creators whose customers or staff mostly carry Android phones: delivery teams, shops, gyms, schools, community groups. It runs online in your browser, so there is nothing to install on your computer. The Android app opens your published app; if you need hand-written native Android screens, look at native tools instead.

What you can build

A delivery app where drivers see today's orders and mark them delivered
A school or class app with timetables and announcements
A shop app where regulars check stock and reserve items
A field-service app with job notes and photos
An event app with the agenda and ticket check-in

How to create an Android app with AI

Start in the chat like any Mythex project and get the app working in the live preview. Publish it, then open Publish → Android and press Build Android app, or type “make this an Android app” in the chat. The build runs on Mythex's machines with no Android Studio, and a card shows each step. When it says Ready to upload, download the file.

Straight to Google Play internal testing

If you'd rather not upload files by hand, connect your own Google service account key once. After that, every Android build also goes to your app's internal testing track, and testers you added in Play Console can install it from the Play Store minutes later. You create the app once in Play Console, because Google doesn't let outside tools do that step. With the account connected, the agent can also update your Play listing and asks before anything goes public.

Free Android app builder? Here's the split

Building and publishing the app itself is free on Mythex, with no credit card, and it opens in Chrome on any Android phone. The Android build that you put on Google Play is part of Pro at $25/month. Google charges its own one-time fee for a Play Console developer account, paid to Google. Many people start free, share the web link with a few customers, and move to Pro once they know the app is worth putting in the store.

A prompt to start from

Build a phone-first app for a small delivery business. Drivers log in and see today's deliveries with the customer name, address and phone number, tap one to open details, and mark it delivered with a photo. The owner sees all deliveries on a dashboard. Use a real database and file storage.

Questions

Do I need Android Studio or a powerful computer?

No. Mythex builds the Android app on its own build machines, so any computer with a browser will do. You start the build from the Publish button or with a sentence in chat.

Is the Android file an APK?

It is an AAB (Android App Bundle), the format Google Play requires for new apps. It isn't for installing on a phone directly; upload it to Play Console, or let Mythex send it to internal testing and install it from there.

Can I make the iPhone version from the same project?

Yes. On Pro, ask for the iPhone build and Mythex sends it to TestFlight using your App Store Connect key. Android and iPhone are built separately, each when you ask for it.

How do I update the app after it's on Google Play?

Change it in chat and press Publish. The Android app opens your published app, so people see the new version without a new download.
