Health
A calm intermittent-fasting timer
Pick a protocol — 16:8, OMAD or your own hours — and a quiet ring tracks your fast, live on the Lock Screen and Dynamic Island. Streaks, a smoothed weight trend and Apple Health vitals, with an app that reports the numbers instead of shouting at you.
What Moonfast does
16:8, 18:6, 20:4, OMAD or your own hours — the ring keeps counting if you go past your goal.
A Live Activity and the Dynamic Island keep the timer at a glance, with Home and Lock Screen widgets for your streak.
A calendar of finished fasts, streaks, weekly averages and personal bests — and no invented numbers when there isn’t enough data.
Log your weight or connect Apple Health, optionally, for a smoothed trend line and vitals charted next to the days you fasted.
No account, no servers, no analytics. Export everything as JSON or delete it whenever you like.
Moonfast is a timer and a log. It is not a medical device and does not give medical advice, diagnosis or treatment.
