A fasting timer that stays out of your way: a clear ring, your streak, your water, your weight, and a reminder to start on time. Offline, without an account.
FASTING WINDOWS
Choose a fasting window and start: 12:12, 14:10, 16:8, 18:6, 20:4 or OMAD (23:1), all included, or set a custom duration from 1 to 23 hours. Started earlier than you pressed the button? Edit the start time of the fast in progress, and correct a finished fast afterwards. Extended fasts from 24 to 72 hours are available with Pro.
TIMER AND REMINDERS
The ring fills from night to dawn and shows the time elapsed, the time left and the stage you are in. A notification tells you when your eating window opens. A daily reminder at the hour you choose helps you start your fast on time. The home screen widget shows the fast in progress with the elapsed time running.
STREAKS AND BADGES
Days in a row where you reached your goal, your longest streak, and badges for milestones: first fast, first 16 hours, 7 days in a row, 100 hours in total and more.
FASTING STAGES
The stages screen describes what is commonly said to happen as hours pass: digestion, falling blood sugar, fat burning, ketosis, autophagy, then long and extended fasting. Durations are approximate and vary from one person to another. This is general information, not medical advice.
WATER, WEIGHT AND MOOD
Count your glasses of water against a daily goal. Log your weight in kilograms or pounds and follow the curve over the last 30 days. When a fast ends, note how you felt and add a short note.
HISTORY AND STATS
Your last 30 days of fasts, with totals, goals reached and your longest fast. Pro opens the full history, your average fast length, the hours fasted this week and this month, the complete weight curve and a CSV export of your fasts.
INCLUDED
All fasting windows up to 23 hours, the timer, notifications, the daily start reminder, the widget, streaks and badges, water, 30 days of weight and history, the stages screen.
PRO
Extended fasts from 24 to 72 hours, full history and statistics, complete weight curve, CSV export of your fasts, and no ads with a paid plan or the 24 hour pass (during the trial, ads stay on). Weekly with a trial period, monthly, a 24 hour pass, or a one-time purchase for life. Prices are shown in the app before any purchase.
WHAT THIS APP DOES NOT DO
No diet plan, no calorie counting, no promise about your weight. Fasting is not suitable for everyone: ask a doctor before fasting if you are pregnant, diabetic, under treatment or under 18.
PRIVACY
Your fasting data stays on your phone. No account, no sign-in. Ads go through the network.
