I’ve tried them all!

I’ve tried every fasting app and always come back to this one. My favorite feature is the timer that also educational. It helps awareness of your internal process like when you are lowering your blood sugar, in the fat burning zone, the ketosis zone. It is extremely motivational! Another feature that is extremely beneficial is it reminds you to drink and log your water! I often get my hunger and thirst cues intertwined so it’s really trained me to hydrate when I used to binge. I also can’t live without the notification that helps you remember to start your fast! It has cut out my late night munchies and blood sugar roller coaster!

Everything is broken - 0 STARS

I got this to share with my friends my fasting journey. It never worked. All my trophies for meeting goals never saved. So many features never worked
and I tried to reach out for customer support as well. I will be vsnkng my membership right before the 1 month mark. I feel robbed.

So far so good

I like the reminders that this app gives me. I am still having a hard time connecting with friends on this app but I like the data and analytics portion that is keeping me motivated to stick with it and keep going. I only started using the app for a week, but I have already lost about 4 pounds. I think this app really helps me stay motivated and I’m looking forward to trying the pro version.

Excellent for beginners

I love the ability to go back and add additional time, if I forgot.

My review.

This app is so colorful. Although it doesn’t allow me fast track my fast but it’s great. I think that’s a feature that should be worked on. Say I started my fast 17:30 and the time I ended the last fast was 17:10, I should be able to take my fast to 17:30. More accuracy.
