There are way too many features behind a paywall that they keep throwing in your face.

Even the free app was great but I up graded to purchase and with it all even better. The explanations given are easy to listen to plus short and full of reminders and direction. I have fasted off and in for many years but this group is professional and interesting. They have done there work. So I am happy to give them my vote with a purchase.

The little articles and videos are quite helpful for understanding. The journal is nice for tracking how I feel and I like how the app looks overall. No complaints

I really love the app and being able to track intermittent fasting. I’m only using the free version right now. My mom uses the paid version and there is not enough difference for me to pay for one more app. I would like to see the app import glucose numbers from my CGM Freestyle Libre.

The timer is super helpful for staying on track with a longer fast.

None of the graphs are accurate and they’ve been trying to ‘fix’ it for 6 months, yet it still doubles my sleep, exercise, etc, rendering these graphs useless. I don’t sleep an average of 16 hours a night. But I appreciate the double exercise, lol.

Among other issues, the "calendar" section does not add the hours for each month correctly. There are about 70 hours missing from December. I contacted support and they had no solution- said it was a big and just deal with it. Horrible.

Love this app and how it holds me accountable. Keeps me on track and I love all of the challenges!
