About ONE:Intermittent Fasting

Fasting made simple. Start a fast in one tap, watch your body move through each stage, and build the streak that actually changes things. ONE is an intermittent fasting tracker for people who want the habit, not the homework. No account. No clutter. Just the timer, the stages, and your progress. CHOOSE YOUR PLAN • 12:12, 14:10, 16:8, 18:6, 20:4 and OMAD (23:1) • Flexi mode for open-ended fasts • A difficulty rating on every plan, so you pick one you'll actually keep • Custom Timer for any length you like — free, no upgrade • Change plan any time. Nothing is locked in. WATCH WHAT'S HAPPENING • Live fasting stages: blood sugar falling, fat burning, ketosis, autophagy • Know exactly when the next stage arrives • Plain-language explanation of what your body is doing, and why STAY ON TRACK • Reminders when your fast starts and ends • A notification as you reach each new stage • Fix your start or end time when life happens • Daily streaks that reward consistency, not perfection • Apple Health: your fasts written out, your weight read in — free SEE YOUR PROGRESS • Every fast logged automatically, nothing to fill in • Your recent fasts, free forever WHAT ONE PREMIUM ADDS • Your full fasting history, not just the last few • AI Coach — weekly and monthly written analysis of how you actually fast, what changed, and what to try next • Trends: streak calendar, fasting-hours charts and weight trend • Protein tracker, with a daily target set from your weight • Water tracking against a goal, right on the timer • Your own Quick Start lengths, tuned to the fasts you really do • Apple Watch app with complications — start and end a fast from your wrist • Home Screen widget and a Live Activity on your Lock Screen The timer, every plan, the stages and the Custom Timer are free.

What’s new

Version 1.4 · Updated September 24, 2026

NEW • Apple Watch app — your fast, the stage you're in and the time left, on your wrist. Start or end a fast without reaching for your phone. • Complications, so your fast sits on your watch face. • Home Screen widget and a Live Activity, so the timer is on your Lock Screen from the moment you start. • AI Coach — weekly and monthly written analysis of how you actually fast, what changed, and what to try next. • Protein tracker, with a daily target worked out from your weight. • Water and protein now sit on the timer itself, beside the ring. • Tap the timer's own numbers to correct a start or end time. SIMPLER • Three tabs. The app opens on the timer, and you can start a fast in under a minute. • No sign-up, no email. An account is optional, and only so your history follows you to a new phone. • Custom Timer is free again, for everyone. • Challenges have been retired. That effort went into the timer, the stages and the Coach instead. FIXED • Fasts that had vanished from your history are back, and starting a new fast can no longer close one that is still running. • Streaks are counted in your own time zone. A late-evening fast could land on the wrong day and quietly break a streak you had earned. • The app remembers the plan you chose after your first fast.
