How can we help?
Most answers are below. For anything else, email us and a person will reply.
I forgot to start or stop the timer
Open History. Tap a fast to correct its start or end time, or tap Add to enter one you didn’t time.
Where are my records kept?
On your phone only. We don’t have a copy, so we can’t restore them for you. See Privacy.
How do I delete everything?
Open the About tab and choose Delete all data.
The hours don’t match how I feel
The app shows what typically happens in a healthy adult. It doesn’t measure your body, and the timing varies from person to person.
Is this medical advice?
No. It is general information. Fasting isn’t safe for everyone: if you are under 18, underweight, pregnant or breastfeeding, have or have had an eating disorder, have a history of low blood sugar, or take diabetes medicine or any medicine that must be taken with food, talk to your doctor first.
