Fast on your schedule without setting it up again every day. Pick your fasting days and start time once β€” FastZen reminds you when it’s time, then keeps elapsed and remaining time on your Lock Screen while the fast runs. SEE THE NEXT SEVEN DAYS Preview your personal schedule before any purchase. With Custom Week, move a start or take a rest day for one date only, without changing the recurring week. Dates and start times follow your local time zone. With a dated exception, reminders cover the next eight weeks and refresh when you open FastZen. SET A RECURRING WEEKLY ROUTINE Choose the days you want to fast and one start time. FastZen schedules repeating local reminders for the selected days. You can change or disable the routine at any time. USE A TIMER THAT KEEPS ITS PLACE Start 16:8, 18:6, 20:4, OMAD, or a custom fast from 1 to 48 hours. FastZen calculates elapsed and remaining time from the saved start date and restores an active session when the app opens again. KEEP THE ACTIVE FAST IN VIEW Live Activities show the plan, progress, remaining time and chosen end time when supported by your iPhone. iOS limits each Live Activity to eight active hours; your session remains saved in the app. REVIEW YOUR OWN HISTORY See completed fasts, duration, completion percentage, total fasting time, and streaks. History stays on your device. EVERYTHING STAYS ON YOUR IPHONE No account, ads, server sync, or external analytics. FREE, WITHOUT LIMITS The timer, the weekly routine, local reminders, Live Activities, the whole history, and correcting a finished fast after the fact cost nothing and have no quota. CUSTOM WEEK β€” ONE-TIME PURCHASE Give each weekday its own protocol and its own start time, mark rest days, and start a fast at the hour you planned when you open the app late. One purchase, no subscription, no renewal, no account. Anyone who used FastZen before version 1.1.0 keeps Custom Week at no charge. FastZen is a timer and routine tool. It does not provide medical advice or promise health outcomes.
