Forced and intrusive ads on every app interaction
Users are repeatedly forced to watch long, unskippable video ads when opening the app, starting/ending a fast, or navigating between features, making basic functionality frustrating.

- “I have to watch a 30 second ad EVERY time I open that app. If you sold an ad-free version for $2.99, I’d happily buy that.”
- “You are forced to watch an ad just to open the app. UNACCEPTABLE.”
- “As soon as you open the app you’re hit with an unskiable ad. It’s one of those shady ads where by trying to press the X button it takes you to the App Store.”
Subscription confusion, billing issues, and lack of refund options
Multiple users report being charged unexpectedly during or after free trials, unable to cancel subscriptions, receiving no refunds despite cancellation attempts, and facing misleading pricing or hidden fees.

- “I wanted the free trial. It said 7 days free then the yearly. I agreed to the trial and they charged me that day and apple won’t refund me.”
- “They charge your without your permission — They offer 7 days free trial with yearly subscription for 49.99$ i subscribe and they charge me 49.99 the same day, without even free trial!!!!”
- “I was Charged but never signed up”

reviews
- “I have paid for the pro annual service on this app. Please explain to me why I don’t have access to the pro services when I have spent $50 for an annual subscription.”
- “The update deleted all my diet records! ... The feature to scan my meals and calculate calories is also gone!”
- “Paid for premium, don’t get it on IOS — I paid for premium a couple weeks ago when I had a android phone. Got a new iPhone and for some reason I don’t have access to premium anymore.”
Data loss and poor data management
Users report losing months of fasting and food tracking data after app updates, reinstalling, or switching devices, with no backup or recovery option.

- “i deleted the app for about an hour and i download it again and log into my account all of my data that i’ve had for about 6 months now is gone”
- “The update deleted all my diet records! — I waked up today to see the app updated and all my diet records are deleted.”
- “Stopped tracking my times after awhile. I would enter my end time of fasting, then later on I would find it erased my end time, and just kept continuing my fast.”
Inability to edit or customize fasting start/end times
Users cannot manually adjust or correct their fasting start/end times, which causes inaccurate tracking and frustration, especially for non-standard fasting windows.

reviews
- “I really hate that I can’t edit the time I started fasting I can only start the fast in real time. All of my times are off because of it.”
- “When I click end fast it doesn’t end! — I will email apple for my money back. Doesn’t work.”
- “I can’t figure out how to edit it. Also tried to manually add food and kept getting a ‘calorie’ error.”
Poor food tracking and AI scanner functionality
The food tracking feature is criticized for lacking a reliable database, failing to recognize scanned foods, requiring manual entry of macros, and being generally unusable.

reviews
- “AI food tracker from scanning is easily fooled”
- “No food database. Have to manually enter all macros. Advertised to easily track food, not true.”
- “Most everything I tried to scan came up as not found. Very frustrated with this part of the app.”
Lack of cross-platform sync and subscription transfer
Users report that premium subscriptions do not transfer between iOS and Android devices, even when using the same account, leading to double payments.

reviews
- “Membership Issue — Subscription does NOT transfer between Android and iOS. No solution so far from developers.”
- “Premium plan didn’t transfer to new phone — I have purchased a new phone, an iPhone and when I load the app onto it, it does not recognize my subscription.”
- “I paid for premium a couple weeks ago when I had a android phone. Got a new iPhone and for some reason I don’t have access to premium anymore.”
Unresponsive customer support and no cancellation path
