flo
Flo is a free, minimalist Pomodoro timer and online focus space. It combines a focus / short break / long break timer with calm animated ambient backgrounds and Brain.fm focus music, plus a task list, notes and session stats. No sign-up is needed: Flo works right away in guest mode with your data stored on this device, and you can optionally sign in with Google later to sync across devices.
Flo uses the Pomodoro technique: work in focused intervals, then take a short break, and a longer break after a few rounds. Timer lengths are customizable.
