A fasting timer that shows you exactly where you are, and widgets that keep it on your home and lock screen. Fasted turns your fasting window into a live timeline.

FREE, FOR GOOD - The full fasting timer with a live progress ring - The 16:8 plan, free forever - Every home screen and lock screen widget, with nothing to buy - The whole stage timeline: every stage name and the hour it starts - Your last 7 days of fasts, your week chart and your streak - Dark, light and automatic themes - A local reminder when your fast is complete UNLOCK PRO, ONCE A single payment. Yours for good. No subscription, no renewal date, no account. - The 18:6, 20:4 and OMAD plans - Open fast: run with no fixed goal and stop when you decide - Deeper insights on the later fasting stages - Your complete fasting history, back to your very first fast HONEST BY DESIGN You pay once and that is it. Nothing renews, and nothing you rely on today moves behind a new paywall tomorrow. There is no account to create and no sign up, and your fasting data stays on your device. ABOUT THE FASTING STAGES The stage timeline is educational and is estimated from elapsed fasting time alone. Fasted does not measure your body. It is a general wellness tool, not medical advice. Intermittent fasting is not right for everyone, so talk to a qualified healthcare professional before you change how you eat. Questions or ideas? fasted@benbasha.com

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 โ€” 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 โ€” "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
