12:12 and 14:10
12 or 14 hours without food, including the night. Often where people start.
Intermittent fasting
Intermittent fasting with a timer that knows your meals.
The berryl fasting timer measures how long you fast: 16:8, 18:6, OMAD or your own plan. Because berryl also knows your meals, the app notices when you forgot to start and asks when you log something during a fast.
- Fasting timer free, without limits
- Reminder when you reach your goal
- Measures time, gives no advice

When is your fast complete?
Pick a plan and the time of your last meal. The timer in the app calculates the same way: the goal is the start plus the fasting hours.
The plans
What does 16:8 mean?
With intermittent fasting you switch between times when you eat and times when you eat nothing. The first number is the hours without food, the second your eating window.
16:8
16 hours without food, an 8-hour eating window, for example from 12:00 to 20:00. Selected by default in berryl.
18:6 and 20:4
A shorter eating window of 6 or 4 hours.
OMAD, 24 h, 36 h
One meal a day or whole fasting days. From 24 hours, berryl shows a note and plans 8 hours for eating between two fasts.
How the fasting timer works
- Start and stop with one tap, on the fasting screen or on the card on “Today”. The ring shows how long you have been fasting and when you reach your goal.
- Forgot to start? If you logged a meal shortly before, the fast can start at the time of that meal.
- Eating during a fast: if you log something with more than 10 kcal, berryl asks whether you want to end the fast. Water, tea and black coffee do not count.
- Correct times and add fasts later: you can change the start and end afterwards and add a fast you forgot to log.
- Days and start time: you choose on which weekdays you fast and, if you like, a fixed start time.
- Reminders “Fasting goal reached” and “Eating window ends”, both off by default.
- Statistics: the week as bars, the last 30 days with average and longest fast, plus your history. Without Premium you see the history of the last 30 days, with Premium all of it.
Fasting and nutrition together
A pure fasting app only shows you the clock. In berryl, fasting, meals and supplements are in one place. A “Fast completed” habit ticks itself off, see Habit tracker. What you eat in your eating window you count with the calorie counter, and you see protein and fiber at a glance, see Protein and fiber.
Important to know
berryl only measures the time. The app does not judge whether fasting suits you and gives no advice. If you are pregnant or breastfeeding, have diabetes, take regular medication, have had an eating disorder or are underweight, or are under 18, talk to your doctor first.
Intermittent fasting with berryl FAQ
Is the fasting timer free?
Yes. Timer, plans, reminders and statistics are free. With Premium you also see your history beyond the last 30 days. Your longest fast stays visible without Premium too.
Which plans are there?
12:12, 14:10, 16:8, 18:6, 20:4, OMAD (23 hours), 24 h, 36 h and your own plans from 10 to 48 hours in half-hour steps.
Does coffee break a fast?
In berryl, water, tea and black coffee do not count. Only an entry with more than 10 kcal brings up the question of whether you want to end the fast. Whether you end it is up to you.
Do I have to fast every day?
No. You choose the weekdays yourself. A missed day is no problem, you simply start again next time.
Does berryl say whether fasting works for me?
berryl measures the time and makes no statement about it. How much you eat is shown by the calorie counter. Whether and how you fast is best discussed with your doctor or a dietitian.
