FastRing is the intermittent fasting timer for people who want to fast, not fiddle. One screen. One button. A single beautiful ring that fills as your fast progresses — and lives right on your Lock Screen and Dynamic Island, so most days you never even open the app. Dead simple Pick a protocol, tap Start. That's it. The ring shows elapsed time, your goal, and the fasting stage you're in. End your fast from the Lock Screen without unlocking your phone. 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 — 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 — blood sugar settling, glycogen depletion, ketosis, the autophagy window. Framed as commonly cited timelines, not medical advice. Recurring schedules Set protocols like "Every Tuesday" and FastRing pre-arms the fast and reminds you an hour before. Privacy is the whole point No account. No sign-up. No analytics. No third-party anything. Your data lives on your device and syncs only through your own private iCloud. We literally cannot see it. Free forever The full timer, every preset, and your last 7 days of history are free, always. Lifetime Unlock — one purchase, $4.99, yours for good: Unlimited history Recurring schedules Home Screen & Lock Screen widgets Stage notifications CSV / JSON export No subscription. No trial that flips into a charge. Pay once, keep it forever. FastRing is not a medical device and does not provide medical advice. Consult a healthcare professional before beginning any fasting regimen, especially if you are pregnant, nursing, diabetic, or have a history of disordered eating.
