About App Forge

App Forge builds a working app from a description: an installable web app, a small utility tool or a starter project for a real Android or iOS app.

How to use App Forge

Describe the browser app and the result it should produce.

Press “Generate app”.

Test the app, refine it, and download the finished HTML.

Can I install the app on my phone?

Web apps you make can be downloaded as an installable package, so they can be added to a phone's home screen like a normal app.

Is App Forge free?

Yes. It is free to use, with no account, no watermark and no paywall. The AI uses a free shared allowance; if it is busy or at its daily limit, try again later or add your own Gemini key.

Are my files uploaded?

Only the text you give the AI leaves your device: it is sent to Google’s Gemini model through MigaBuilder’s free AI service, or through your own Gemini key if you add one. Editing, previews and downloads all happen in your browser.
