No subscription. One-time purchase, yours for good. A simple timer that measures and logs how long you fast. It never promises results or claims changes to your body — it just shows your own records, honestly. STARTING TAKES ONE TAP - Choose from 12:12 (a gentle start), 14:10, 16:8 (the classic), 18:6, 20:4, or OMAD (23:1) - Your last preset is remembered, so next time it's a single tap - Prefer your own length? Enter a custom fasting window LOGGING NEVER MAKES YOU CHOOSE - Just two buttons: "Start fasting" and "End the fast" - Ending early still gets logged as a fact, with no judging words — "5h 30m logged," nothing more - Change your mind within a minute of starting and undo without keeping a record STREAK AND WEEKLY TOTALS - Your streak is shown as a simple calendar, not a score to chase - See your weekly total, the average per fast and how many fasts you logged (the weekly totals unlock with the one-time purchase) A TREND FROM YOUR OWN RECORDS - Once 7 completed fasts build up, you'll see something like "you tend to start in the evening" based on your own history (unlocked by the one-time purchase) - This is a statistic from your past records, not health advice or a diagnosis. We never say a time is "best" for you QUIET AT NIGHT - No notifications between 22:00 and 6:00 by default. If the fast time would have been reached overnight, you get a single honest notice once the quiet hours end AI NOTE (SUPPORTED DEVICES AND LANGUAGES ONLY) - On iPhones that support Apple Intelligence (iOS 26 or later), the on-device AI writes a short note and a guide for your next fast from your log right away, with no extra download. It appears on the Trend screen (unlocked by the one-time purchase) - On slower devices and in languages that are not supported, the AI is not used and the "Note on your log" is shown instead - Your records are never sent anywhere. The iPhone app downloads nothing - Not medical advice or a diagnosis BEFORE YOU START - If you have a medical condition, are pregnant or breastfeeding, are a growing child, or have a history of an eating disorder, please talk to a doctor first - This app times and records your fasting. It does not diagnose or treat anything BUILT TO BE TRUSTED - Your records are never sent off the device. The iPhone app uses no network - Export and import your records (backup, moving to a new device) any time, free - No account required - No ads - The 16:8 preset, logging, and your streak are free to use for good
