How to go from a sentence to a running app
In one sentence
BuildMyAPK works in four steps: describe the app, wait for a live phone preview, chat to refine the same project, then export source or build an APK. The AI writes a real Expo app in a cloud sandbox — you stay in the browser.

What happens after you hit send
A coding agent writes project files in an isolated sandbox, starts Metro, and returns a preview URL. Follow-ups restore the last snapshot, patch files, and refresh the same preview.
What you can add later
Optional Express/Mongo backend, website URL brand import, Expo Go QR, USB install via Device Bridge after an EAS artifact exists.
FAQ
How long until I see a preview?
First generation is a full app build in the sandbox, so it takes longer than a follow-up edit. Stay on the project page; the preview appears when the job finishes.
Can I change the app after the first generation?
Yes. Chat follow-ups keep editing the same project — screens, layout, theme, and flows.
