ONE:Intermittent Fasting
Fast Timer, Protein Tracker
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.

Ratings & Reviews
This is ONE, rebuilt.
The timer is the home screen now. You open the app and your fast is there — no menu, no setup.
PICK A PLAN, NOT A NUMBER
• Named plans: 12:12, 14:10, 16:8, 18:6, 20:4, OMAD and Flexi, each with a difficulty rating so you choose one you'll actually keep
• The custom timer is free again — set whatever hours suit you
• Switch plans whenever you like, and your choice is remembered
START IN SECONDS
• No sign-up. Your first fast starts while you're still setting up, so you're fasting before you've finished looking around
• An account is optional and exists for one reason: your history survives a new phone
WATCH THE FAST, NOT THE CLOCK
• Live stages as you go — digesting, burning glycogen, fat burning, deep fat burn — with the hours each one covers and a plain-language note on what your body is doing
• A Lock Screen Live Activity and a Home Screen widget, so the running fast is there without opening the app
• Apple Health, free for everyone
AI COACH — ONE Premium
• Weekly and monthly reads of your own fasts: what changed, and what to try next
• Protein guidance against your target
• Every number is worked out on your device. The coach writes the words, never the arithmetic
STAY CONSISTENT
• Reminders at the halfway mark, shortly before the end, and when the fast completes
• Weekly and monthly summaries
• Streak, water and protein all on the timer screen
ALSO IN THIS UPDATE
• Follows your system light or dark theme
• Your plan is remembered after the first fast
• Signing out actually signs you out, and deleting your account gives you a genuine fresh start
• The timer no longer says a fast is running when it isn't
• Challenges have been removed
• The app no longer asks for camera, microphone or location access — it never needed them
