FastRing
Simple, private fasting timer.
The Lock Screen is the app. Start a fast and forget it — your ring, elapsed time, and stage sit on the Lock Screen and Dynamic Island, so most days you never even open FastRing. One screen, one button, no account, no tracking. It's the intermittent fasting timer for people who want to fast, not fiddle.
Features
- Pick a protocol, tap Start — a single ring shows elapsed time, your goal, and the stage you're in
- Live Activity and Dynamic Island through fasts as long as 36 hours; end a fast without unlocking your phone
- Presets for 16:8, 18:6, 20:4, OMAD (23:1), 36-hour, or any custom length — and backdating in two taps
- A GitHub-style history heatmap with current and longest streaks and your 7-day average
- Optional notes on commonly cited fasting milestones — blood sugar, glycogen, ketosis, the autophagy window
- Recurring schedules like "Every Tuesday," pre-armed with a reminder an hour before
- No account, no analytics, no third-party anything — your data syncs only through your own private iCloud
Pricing
The full timer, every preset, and your last 7 days of history are free, always. A one-time Lifetime Unlock adds unlimited history, recurring schedules, Home Screen and Lock Screen widgets, stage notifications, and CSV / JSON export. No subscription, and no trial that flips into a charge.
