About Atomic Habits Timer - 1% Habit
Track habits in 15-minute sessions, each about 1% of a day. See completed sessions on a daily grid. No streak is required. HOW IT WORKS • Pick routines — exercise, reading, meditation, study, a walk, anything. Each gets its own color or emoji. • Tap one to start a live 15-minute timer. • Finish it and it counts as one rep — a filled tile on your time-of-day heatmap. • Stack a few reps and watch today's % climb: 1%, 2%, 5%… WIDGETS & APPLE WATCH • Home Screen and Lock Screen widgets show today's % and your heatmap at a glance. • Start a routine right from your wrist with the Apple Watch app — reps you do on the watch sync back to your iPhone. DATA Your routines and completed sessions are stored on your device. No account is required. Usage events are sent to Pentarab’s own analytics service. 1% PRO Unlimited routines, full history and the Apple Watch app — as a monthly or yearly subscription, or as a one-time purchase that keeps them for good.
