Got questions? We have answers.

Can intermittent fasting help me lose weight?

Yes! Fasting alters how often you eat, which helps you eat less without counting calories or going on a diet. Intermittent fasting also encourages healthier, more conscientious choices around what you eat. Finally, intermittent fasting enables your body to tap into its fat stores for fuel so that you burn fat faster.

I like the interface, but there's several things that seem to be broken in the Free version. For example, streaks & milestones are not being earned or incremented. Also, the week view for the Total Fasting Hours chart is not accurate. It has not shown anything since 10/28 and the hours that are displayed for that day do not even reflect what was recorded for the fast itself. -- If you don't care about any of that stuff and just want to track your fast each day, the Today & Calendar views work.

This app is broken. It constantly doesn't load when opening the app and makes it difficult to start or stop fasts sometimes. I accidentally let the timer run for over a day and the app would not save the new completed time and even when I tried to delete the fast altogether it would not delete and let me restart a fast. This app is nearly unusable. It's sad I've only been using it for about a month and really wanted to like it more.

Update: they fixed it! Yay! Back to 5 stars! Update: Unusable on Pixel 8 Pro, will not open. Developers advised with no response. Sorry to see that. Best fasting app I've seen. Comprehensive, actively encouraging, continuous development and refinement, no ads. Very impressed with the app's quality and user experience. Thanks, developers!
