Lots of easy ways to do fasting with information to boot. I’ve used the free app forever with no issues.

I love this app. Then after an update the Journey tab went away. That was kinda my life line (besides the main page with the countdown). On the Journey tab I could scroll through and see all my fasts and see my weight. I could watch my weight dropping as I had more consistent days in a row of fasting. This was highly motivating to me. Please bring it back. Oh, and weirdly when I signed up for coaching my success rate plummeted. I did better with picking a fast that was going to work each day than feeling like a failure if I didn’t do what the app coach recommended. I kept mucking around with the coach and finally decided it wasn’t for me. So, if you’re someone who’s having a hard time using coaching, maybe it’s also not for you.

I’m an expert in fasting and this app is by far the best and most useful. I have been using it for years, I love it.

Tried many diff apps for fasting but this one stuck. It is simple and does all I want. Wish the monthly subscription was cheaper.

Simple but polished app to track my intermittent fasts. I have been using the app for over two years and it has served its purpose very well as a tracking app. Additionally it introduced me to new and meaningful health information from the latest research around intermittent fasting as well as some longer fasts. My longest fast is 72 hours but I have heard of people using it for 7 day fasts just as well. High reliability, the app has never crashed or hung for me, which I would expect from a tracking app that values simplicity and utility.

I don’t use too many apps to keep track of sitting and standing, but this App is helpful to keep track of your fasting hours and the UI is beautiful.

now demands so much info before you can do anything and custom fast is limited to only 7 days...i rather use timer
