About this app

A simple intermittent fasting timer that does not lock the basics behind a subscription.

Every plan, every statistic and your full history are free. No account, no sign-in, no paywall screen when you open the app.

PLANS
- 13:11, 14:10, 16:8, 18:6, 20:4
- OMAD (23:1), 24-hour and 36-hour fasts
- Custom: any length from 1 to 72 hours
- Weekly schedule: a different plan for each day, or 5:2 in one tap. Rest days never break your streak
Change the goal in the middle of a fast and the timer keeps going.

TIMER
- Big live timer with a progress ring
- Time left and the exact clock time you reach your goal
- Eating window countdown after each fast, with the time your next fast starts
- Forgot to press start? Set the start time in the past
- Home screen widget that counts your fast up and your eating window down

REMINDERS (turn on the ones you want)
- Live progress in the notification shade: your fast counts up, your eating window counts down
- When you reach your goal
- One hour before your goal
- When your eating window ends
- A daily reminder to start fasting at a time you choose

HISTORY AND STATS
- Current streak and best streak
- 7-day average and longest fast
- Last 7 days chart and a monthly calendar
- Add a note to any fast
- Edit the start or end of any past fast, or delete it
- No limit on how many fasts you can keep

WEIGHT, WATER, MEALS AND MEASUREMENTS
- Log your weight in kg or lb and see a chart of your progress
- Count cups of water with a daily goal
- Write down what you ate, with calories if you like — no food database to fight with
- Track your waist and body fat

YOUR DATA STAYS ON YOUR PHONE
Everything is stored only on your device. Nothing is uploaded to a server, and there is no account that can be logged out and lost. Export a CSV backup to keep a copy or open it in a spreadsheet, and import it on a new phone.

HOW IT IS FREE
The app shows a small banner at the bottom and, now and then, a full-screen ad after you finish a fast. Never while the timer is running and never when you start a fast.

IMPORTANT
Fasting Timer is a timer and log. It is not a medical device and does not diagnose, treat, cure or prevent any medical condition. Talk to a doctor before fasting if you are pregnant, breastfeeding, diabetic, underweight, have a history of eating disorders, or take medication.

Also available in Spanish and Korean.
Intermittent fasting timer & tracker. All plans free. No subscription, no login.
