Overview
FocusBottle is a focus-companion app for Android that turns focus timing into a visual, collectible experience. While you focus, light particles inside a bottle dance and evolve with your concentration level; when a session ends, every stretch of time is gathered, recorded, and visualized.
Unlike ordinary timers that only track minutes, FocusBottle makes focus visible through its core Light Particle System — particles multiply, evolve, and become more beautiful as your account level rises through 4 tiers (Guardian golden glow → Starwalker tri-color stardust → Aurora Master rainbow aurora). It's free, requires no sign-up, and works fully offline.
The app combines a Pomodoro timer (25/50/90 min modes) with task management, a focus calendar heatmap, achievement/level system, white noise (rain/waves/café/wind), shareable focus cards, and 4 themed bottle skins. Cloud sync via Google account keeps data safe across devices.
