Holdfast times your fast. That is the whole app - no quiz to sit through, no goal weight, no projection curves, no programme to follow. Start the timer, get on with your day, and it tells you when you are done. FREE, AND STAYING FREE - The timer, every preset, and your complete history - An alert at your goal that breaks through Focus, or a real alarm that sounds even on silent (iOS 26 and later) - Live Activity and Dynamic Island, so a running fast is on your lock screen without opening anything - Fasting stages as they pass, described in plain words - Forgot to start it? Move the start. Forgot to stop? Move the end. Add fasts you never timed at all. - Export everything as CSV, always PRO, BOUGHT ONCE - Home and lock screen widgets, so Holdfast is there without opening it - Insights: your months, your typical fast, the days you actually fasted - Extra heads-up alerts before your goal - Automatic backup to your own iCloud - An alternate app icon There is no subscription in Holdfast, and there will not be one. Most apps in this category cost more every year than Holdfast costs a single time. NOTHING LEAVES YOUR PHONE No account, no sign-up, no analytics, no ads, no servers holding your history. Your fasts are stored on your device, and we cannot read them. Available in English, Spanish, French, German, Italian and Portuguese. Holdfast is a timer, not medical advice. Talk to a doctor before changing how you eat.
