A focus timer where light particles visualize your concentration
About FocusBottle
FocusBottle is an Android focus-companion app that turns focus timing into a visible, collectible experience. While you focus, light particles inside a bottle dance and evolve with your level of concentration; when a session ends, every stretch of time is gathered, recorded, and visualized on a calendar heatmap.
Unlike ordinary Pomodoro timers, the bottle itself evolves through 4 stages (Glass, Crystal, Starlight, Aurora) as you level up. Includes 25/50/90 min modes, a focus calendar heatmap, task binding, white noise, and share cards. Core features are free, work offline, and need no sign-up.
