See how long you've been fasting right on your Lock Screen — without opening the app. Fasting Timer is an intermittent fasting clock that shows your day as a 24-hour dial. Instead of a progress bar, your fast is drawn as an arc on a real clock face — "from 9:30 last night until 1:30 this afternoon" — so you see when you can eat, not just how long you've held on. ● Lock Screen widgets, Live Activity and Dynamic Island — always accurate, even with the app closed ● No 23-hour cap — the arc keeps growing past your goal ● Zero ads, no account, no server — fully local, works offline ● Your history stays — a 30-day dial calendar plus automatic iCloud backup ● Reminders for your first meal and your next fast Free forever - Timer with 16:8, 18:6, 20:4 and OMAD presets - Lock Screen widgets (circular, rectangular, inline) and Live Activity - Overtime counting, 30-day history, iCloud backup Premium (subscription) - Custom fast length (1–72 hours) and extended 36/72-hour fasts - Full history beyond 30 days - CSV export About subscriptions: Premium is a monthly or yearly subscription.
