Personal Android App Builder for Tools on Your Phone

NiuNiu is built for personal Android apps: small, practical tools you can describe in chat, install as APKs, and improve over time through OTA updates where compatible and fresh APKs when native changes require them.

What you can build

Common projects include habit trackers, family reminders, workout logs, expense trackers, study planners, journals, inventory checklists, local calculators, and lightweight AI assistants.

When to choose another tool

Choose a different platform if you need a complex backend, public marketplace, multi-user SaaS dashboard, iOS-first launch, or visual drag-and-drop control over every screen.
