NiuNiu is an AI Android app builder that works through chat. You describe what you want in plain language and it produces a custom Android app as a locally installable APK file.
What sets it apart is what happens next. Improvements can be requested through chat after the app is already installed, delivered either as compatible over-the-air updates or as a repackaged APK where that is necessary.
Apps built this way are local-first by design, keeping data on the device itself wherever that is feasible, which supports privacy without requiring a separate policy to enforce it.
That combination suits personal software rather than products: habit trackers, reminder tools, private AI assistants, planning and coaching utilities, and local-first trackers of most kinds. Pricing starts at $5 per unit.
