Local-First Android App Builder for Private Tools

NiuNiu is designed for personal Android apps where private records can stay on the phone by default, with external services called out during planning.

Why local-first matters

For habit logs, expenses, journals, health notes, and personal databases, the best place for everyday records is often the device you already control.

What still needs a service

Some features need outside systems, such as AI APIs, maps, payments, cloud sync, or shared accounts. NiuNiu flags those tradeoffs before the build starts.
