An editorial reading of the saved reviews
An intermittent fasting timer with a polished fat-burning phase visualization, but the free version's functionality is cut to a bare minimum.

What people use it for
People willing to pay for a subscription from day one who want motivating phase visualization.
What reviews praise
- A 'flame' animation during peak fat-burning phase genuinely motivates users to keep going.
- People who lost 20-30 pounds credit this visual cue as a key driver.
What reviews complain about
- The target weight algorithm has a serious bug: it substitutes someone else's parameters in place of the ones you entered.
- The app gives no warning about maximum safe fasting duration, which is a risk for vulnerable users.
What users experience
1 excerpt from the breakdown. These are individual cases, not a verdict on all users.
The meal logger is so obnoxious. I could eat an entire buffalo and wheel of cheese and this stupid thing would still be like, 'yeah, maybe you should add an egg for extra protein next time.'
