Hi HN — I built Focus Streak, a lightweight habit tracker for Android focused on streak-based motivation and privacy-first design.

Key points: - Streak-based motivation + calendar view and stats - Custom habits, multiple reminders, and offline-first (no account required) - Minimal UI designed to reduce friction and help users actually keep daily routines - Built with React Native + Expo; recently published to Google Play

I’d love feedback on: - UX: what frustrates you on habit apps today? - Growth/ASO: best tactics we should try next? - Any crash/bug reports (device model + android version helps)

Play Store: https://play.google.com/store/apps/details?id=com.focusstrea...

Thanks — I’ll be around to reply to comments and answer technical questions.
