User Reviews

Users frequently praise the app for its core fasting-tracking and editing features, plus a helpful calendar view and overall positive sentiment from long-term use. However, widespread complaints focus on pricing/paywalls, unreliable cross-device syncing, data loss with no cloud backup, poor support and refunds, and performance issues (lag, crashes, slow responses). These recurring negatives significantly color overall satisfaction, especially among users who expect stable syncing, data integrity, and responsive support.

Pros

Core fasting tracking functionality (tracking fasting hours) is valued by long-time users.
Ability to edit entries and times to correct data when mistakes occur.
Calendar view of fasting hours and eating window provides clear visualization.
Generally positive sentiment with users noting long-term use and appreciation for the app.

Cons

Substantial subscription pricing and frequent price increases/paywalls, making it feel not worth the cost.
Data syncing across multiple devices (iPad, iPhone, Apple Watch) often fails or is inconsistent.
Data loss after reinstall and lack of cloud backup, leading to loss of months/years of data.
Poor or unresponsive customer support and problematic billing/cancellation experiences.
Reliability issues such as lag, slow data entry, and occasional crashes or app not opening after updates.

This app should work to sync data amongst my iPad my phone and my watch but doesn’t. I have to choose which one to work with and be near it to enter data. The ability to edit water after the fact because this doesn’t sync amongst the three devices adds to the annoyance. And sometimes the water “meter” does not rest to zero for new day or fasting period. Overall nice app but not worth the money I paid. I’d go freebie version instead. Finally, while I can edit windows, I’m noticing that accuracy is not consistent - reports streaks that are actually far longer than posted … that I find particularly irritating! I have to go in and edit or just accept it believes that I broke I fasting streak when I didn’t. Lagging and odd delays with from one screen to another getting excessive and frustrating!

It says the manual plan is free but it won’t work. I emailed them and they claimed had to by my phone and that I needed to reset it. I did everything I could on my end but nothing works. It’s an issue with the app.
