Fasting made effortless. One tap to start, a calm live timer, stage milestones, streaks, and gentle reminders. No accounts, no ads, fully offline. FastOnce is the simplest intermittent fasting timer on the App Store. One tap starts your fast. A clean, calm timer ring shows exactly where you are — time elapsed, time remaining, and the stage your body is moving through. - Plans for everyone: 12:12, 14:10, 16:8, 18:6, 20:4, OMAD, or set your own length or finish time - A live timer that survives restarts — your fast keeps counting even if you close the app or reboot - Fasting stages on the ring: blood sugar drop, fat burning, ketosis, autophagy — each explained in plain language - Forgot to start? Backdate your start time in a tap - History calendar with current and longest streaks - Stats with 7- and 30-day charts - Gentle reminders at your halfway point, each stage, and when your fast completes - Supportive tips and hydration nudges to help you ride out cravings - Home Screen widget showing your live progress No accounts. No subscriptions. No ads. No tracking. Everything stays on your device, fully offline. FastOnce is general wellbeing information, not medical advice. Talk to a doctor before changing your eating habits.
