Type what your app should do. An AI agent writes genuine React Native or Flutter code, runs it on a live phone preview in your browser, and hands you an installable Android APK — with a hosted backend and database when your app needs one.
Runs in your browser · nothing to install · no credit card to start
The agent writes React Native or Flutter — actual source files you can read, edit and keep. No widget assembly, no proprietary runtime, no lock-in.
Your app runs in a device emulator in the browser as it is being built. Tap through screens, test flows and see every change instantly.
When your app needs to store data or expose an API, the agent provisions a hosted backend with a real database automatically — in the preview and in the installed app.
Camera, GPS, notifications, biometrics, speech, media, file storage and more ship preinstalled in the Android build — and are emulated in the browser preview so you can test them before installing.
Change anything by asking: “make the theme green”, “add a settings screen”, “store entries per user”. The agent edits the code and checks its own work.
Ask for the APK and a release-signed Android package builds on our servers — download it from the chat and install it on any Android device.
“A habit tracker with streaks, reminders and a weekly report.” The agent plans screens, data and logic — and asks when it needs a decision.
Real code is written file by file. The agent runs the app itself and fixes the errors it finds before you ever see them.
A phone emulator in your browser runs the real app. Tap it, break it, ask for changes — every edit re-renders live.
One request builds a release-signed APK with your app’s name and icon. Download from the chat and install.
Habit trackers, budgets, workout logs, reading lists — the app you always wanted, exactly how you want it.
A loyalty card for a café, a booking form for a barber, a menu with daily specials — installed on your customers’ phones.
Checklists, inspections, stock counts and data capture for teams — with a shared backend so everyone sees the same data.
