ONE:Intermittent Fasting

No sign-up, no clutter. Start your first fast in one tap and watch every stage as your body moves through it — 12:12 to OMAD, on screen or on your Lock Screen.

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 timer and tracker built for people who want the habit, not the homework — a simple fasting app, similar to bodyfast approaches. No account. No clutter. Just the timer, the stages, and your progress.

Whether you're starting fasting or already experienced, ONE keeps you consistent — ideal if you're looking for a bodyfast-style fasting experience without the clutter.

CHOOSE YOUR PLAN • 12:12, 14:10, 16:8, 18:6, 20:4 and OMAD (23:1) • Flexi mode for open-ended fasts • Difficulty rating on every plan, so you pick one you'll actually keep • 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 • End your fast straight from the notification • Fix your start or end time when life happens • Daily streaks that reward consistency, not perfection

SEE YOUR PROGRESS • Every fast, logged automatically • Streak calendar and total fasting hours • Weight and water tracking • Weekly and monthly AI summaries that read your data and tell you what changed — and what to try next

BUILT TO STAY OUT OF THE WAY • Start fasting in under a minute — no sign-up • Works offline • Optional backup so your history follows you to a new phone

ONE Premium unlocks full history, trends, the AI coach, custom plans and cloud backup. The timer itself is free, forever.
