1. ★★★★★subscription and paid restrictions

   Too many pay walls. I came back to this app after a few years and the only thing accessible on the free version now is the timer. And the pop ups to try a subscription every time I open the app are making me delete this for good.

2. ★★★★★negative experience without a specific reason· unspecific

   Greedy and shady behavior. I’ve had this app for three years. It was always free. Now to even open the app they want you to pay now. I can’t even get to my profile or see my past stats. The minute you open the app you have to pay to unlock. Smh this is so greedy and shows this will be their downfall.

3. ★★★★★trial charges and refunds

   Faulty App and Fraudulent Charges. I wanted to try this app for the free 7 day trial and the app said it would notify me before charging me for the subscription. After a few days, I decided I didn’t want to subscribe, but no matter how many times I tried to get to my subscription in the app, the app locked up and refused to let me cancel. Then, without notifying me, they charged me for the full year. Will be reporting to BBB.

4. ★★★★★negative experience without a specific reason· unspecific

   No good. Won’t let me do anything without a purchase? Thought the app was supposed to be free from what I’ve heard

5. ★★★★★subscription and paid restrictions

   Paywall. After being a loyal user for awhile now I am now being forced to PAY?? This was an integral part of my diet and life. I’m so upset they are forcing us to pay. I WILL not be doing that. There are zero benefits to paying for it except for my past data. Unfortunately I will be finding a new way to track which is so unfortunate.

6. ★★★★★negative experience without a specific reason· unspecific

   Only good for tracking water and fast. Easier to log food on MyFitnessPal

7. ★★★★★negative experience without a specific reason· unspecific

   Buyer beware. Cancelling is a nightmare

8. ★★★★★negative experience without a specific reason· unspecific

   Used to be good, now spams you with ads you can't x out of. Title

9. ★★★★★privacy and excessive permissions

   Zero:Fasting and Food Tracker. Don’t like it, because it keeps showing the free trial, and it says that I’ve got my Parents approval. I’m 48 years old, and I don’t need their permission.

10. ★★★★★crashes, freezes and errors

    Forced free trail sign up. Once I got set up with the app I could not move forward without signing up for a free trial and providing a credit card. Hoping this was a glitch? Otherwise that is horrible shady user experience.

11. ★★★★★negative experience without a specific reason· unspecific

    not free. I only downloaded this because it was listed as the best of the free tracking apps. It’s not free at all, there’s no free version whatsoever. That’s false advertising and is illegal.

12. ★★★★★negative experience without a specific reason· unspecific

    This app doesn’t work. There’s no way to properly enter a meal. For the app to determine calories or macros. The enter a meal field just has you typing or take a pic. And guess what all this is a lot of data for them to sell. Without actually doing any work for you. Skip this app.

13. ★★★★★negative experience without a specific reason· unspecific

    Not worth it.. Terrible app. Gimmick. Not even a free trial is worth having this app.

14. ★★★★★negative experience without a specific reason· unspecific

    Complete Garbage. Couldn’t even make it past the 3rd screen to try and sign it without it crashing every time. Junk.

15. ★★★★★subscription and paid restrictions

    Forced upgrade suspicious!. I have a paid for annual subscription, being forced to upgrade is suspicious and makes believe there is nefarious intentions by the developers. Highly don’t recommend!

16. ★★★★★trial charges and refunds

    Forces you to get subscriptions. Just wanted to track fasting, would not let me close out of free trial where it charges in a few days. Misleading so say there’s a free option when you can’t opt out and try basic.

17. ★★★★★subscription and paid restrictions

    Hard paywall. Have to pay to use

18. ★★★★★privacy and excessive permissions

    Feels like a database trap. Can’t look at any functionality without a major input of personal data.

19. ★★★★★subscription and paid restrictions

    Not free. The app is not free but you do get 3 days free and then they charge you for a full year.

20. ★★★★★negative experience without a specific reason· unspecific

    Deleting Fasts over 24 hours. I would appreciate it if you could look at this app. There have been several instances where it has deleted fasts for no apparent reason other than the fact that they went over 24 hours. I was using this to help me track my progress, but obviously that’s not going to happen as I cannot remember the specific times. I just know it was showing me at 23 consecutive fast. Before a 24 hour fast then reduce that to just two consecutive fasts.

21. ★★★★★negative experience without a specific reason· unspecific

    Terrible. I want to use the free features but it won’t let me unless I sign up for a free trial. Not trust worthy. Scam.

22. ★★★★★subscription and paid restrictions

    Cost. I had the old version of this app for years and went to update my phone and redownloaded it only to find out I now have to pay for it. I don’t want all the fancy stuff they charge for now and it sucks you can’t even use it anymore with out a subscription

23. ★★★★★negative experience without a specific reason· unspecific

    Idiotic. Congratulations on building a bare bones app, which provides zero information, motivation or guidance during a fasting state. What are you asking $$ for? So I can tell you the start and end day of my fast? Lol, what a joke

24. ★★★★★subscription and paid restrictions

    Not worth it. It’s a paid app

25. ★★★★★negative experience without a specific reason· unspecific

    Widget does not work. Widget continues to count your fasting timer even after you end the fast. Haven’t fixed for months. App now completely useless.

26. ★★★★★negative experience without a specific reason· unspecific

    Was Free, Now Expensive. I used to love this app. I had stopped using it for a while to start 2026 as the year has been pretty crazy. Finally was in a spot where I am ready to get back into fasting and opened the app to find out you HAVE to pay to use it now. Disgusting. Any app that claims to care about health and then charges $70 to use it is lying about caring about your health. Only cares about your money. I noticed they added that AI calorie counter thing where it guesses the calories based off a picture, and I bet that’s why it s so expensive now, because AI is expensive. News flash, NOBODY WANTS THAT BS!!!

27. ★★★★★negative experience without a specific reason· unspecific

    Not free and such a long sign up process.. Don’t waste your time it wasted 9 min on my day when I easily downloaded fast yin 30 seconds hopefully they don’t delete this review. 0 stars.

28. ★★★★★subscription and paid restrictions

    Watch app not working. I have paid subscription but why is the app on my Apple Watch not working… please fix

29. ★★★★★negative experience without a specific reason· unspecific

    Used to be good. Impossible to sign in without giving all your details and even if you do put details in it’s a 50/50 shot it will work.

30. ★★★★★trial charges and refunds

    Can’t use a free version?. Since when does it force you to do a trial or pay for a subscription
