FastLine is the intermittent fasting timer that does the one thing you actually open the app for โ€” beautifully โ€” and doesn't charge you $70 a year for a countdown. Start a fast and a clean count-up ring shows your elapsed time, your current stage, and how long until your goal. It lives where you'll actually see it: on your Lock Screen and in the Dynamic Island as a Live Activity, and on your Home Screen as a widget. No need to keep opening the app. HONEST PRICING The timer, fasting stages, history and stats are free, forever. Pro is an optional upgrade at a fair price โ€” about twenty dollars a year, or a one-time lifetime unlock โ€” not a $70 subscription hidden behind a countdown. WHAT YOU GET, FREE โ€ข Count-up fasting ring with time elapsed and time remaining โ€ข Popular protocols: 16:8, 18:6, 20:4 and OMAD โ€ข Live Activity on the Lock Screen + Dynamic Island โ€ข Home Screen widget โ€ข Educational fasting stages as the hours pass โ€ข History, current streak, averages and a 14-day chart PRO (OPTIONAL) โ€ข Custom fasting goals โ€” set your own hours โ€ข Mood & energy notes on every fast โ€ข Weight trend from Apple Health โ€ข Export your history to CSV ON YOUR WRIST Glance at your fast on Apple Watch and start or end it without reaching for your phone. PRIVATE BY DEFAULT No account. No backend. Your fasts stay on your device. FastLine reads your weight from Apple Health only if you turn it on, and never writes your data anywhere. A NOTE ON HEALTH FastLine is an educational tracking tool, not medical advice. Fasting isn't right for everyone โ€” talk to a doctor before making changes, especially if you are pregnant, nursing, taking medication, or have a history of disordered eating.

Presets for every style 16:8, 18:6, 20:4, OMAD (23:1), 36-hour, or any custom length. Started earlier? Backdate it in two taps. The Lock Screen is the app A Live Activity and Dynamic Island keep your ring, elapsed time, and current stage in front of you โ€” through fasts as long as 36 hours, with no notifications spam. See your streak build A GitHub-style history heatmap, current and longest streaks, and your 7-day average. Watch the grid fill in. Fasting stages, clearly explained Gentle, optional notes as you move through commonly cited milestones โ€” blood sugar settling, glycogen depletion, ketosis, the autophagy window.
