does a decent job of helping keep track of fasting and letting you earn days off. When it was working. It went if the rails a few days and lost my fasts. It also constantly reminds me to start fasts while I'm the middle of one. The constant pressure to pay for recipes and tips is annoying. I'd pay a one time fee if I could get rid of their adds, but monthly isn't worth it.

After taking some time off from this app, I thought I might give it another shot. There are many positive things about this app (Easy to use, water count, goals...) but it is a bit discouraging since you cannot manually add your sports activity. I don't carry my phone with me everywhere nor wish to instal another app to count my steps. I do pilates, hiking, walking. It would be great if I could add those activites there to keep track and motivate myself. Please add this feature to your app.

I recall my "so far so good" and and drop this app to 2 stars. From what i can tell the last update has caused me to lose the ability to press the Start Fasting button. I can not start anything, i have to edit my days manually only. It looks like a bunch of the buttons are not working as well. If someone could contact me, that would be great as i paid for the Yearly Service and this feels a bit like a let down that the app is bugging out. Thank you. Hopefully we can get you back to 5 Stars🌟
