Worst app ever

I’ve had this app about five minutes and I was stupid to pay for it. I’ve never used a more difficult and frustrating app. You have no control at all and you cannot reset a fast if it’s logged wrong or starts at the incorrect time. Rip off!

Do not download

It doesn’t even give you an option to try it out first like other fasting apps! You have to pay to continue. Deleted!!!!

Negative

Used the word lazy in a notification to me. Wow!!! I wish I could get a refund. How negative and awful.

Not impressed with the subscription push.

I had used this app for years without a subscription, but had a lapse of usage, so when I went to log back on, it wouldn’t even let me log in without signing up for a subscription. I don’t appreciate the fact that it now is mandatory, when I was perfectly fine with the free version. Will not be using again.

Long-standing glitches

This is an easy and straight forward fasting timer app but I’ve had this for years and have never been able to go back and edit a fasting entry (if I made a mistake on the time or something) without the app freezing and shutting down… it would be nice if the app actually let you edit fasting logs.
