If I start a 20-hour fast at 8:00 AM, when can I eat?
Quick answer
If you start a 20-hour fast at 8:00 AM, your fast ends at 4:00 AM the next day.
Step by step
01 Tap start at 8:00 AM.
02 Set the target duration to 20 hours.
03 Plan your first meal for 4:00 AM the next day.
The longer answer
The calculation is simple: start time + 20 hours = end time. For this example, 8:00 AM plus 20 hours equals 4:00 AM the next day. Use a timer instead of mental math so you do not keep checking the clock.
Tip
Put the end time on your lock screen or widget so fasting feels less vague.
Common mistake
Restarting the timer repeatedly because the end time was not clear.
Track in the app
Track start time, target duration, end time, and actual completion time.
