Most focus apps polish the timer and treat breaks as dead time, so we skip them. ZenFlow makes the break the reward. Each one opens a living world: a koi pond that keeps living while you work (feed, pair and hatch koi), color mosaics to restore, a paper plane to glide through four lands. No scores, no streaks to lose. Around it: a Pomodoro timer with 20-20-20 eye breaks, one-click focus workflows, website and app blocking, and weekly AI insights written on-device. No account, no tracking.
