User Reviews

Users praise the app for simple meal logging and its role in contributing data to science. However, recurring problems hinder use: data logs stuck as pending and baseline/history preventing reports, poor Apple Health/sleep integration, registration/support issues, and bugs after updates that reduce reliability.
Pros
  • Easy to log meals and track eating window
  • Simple, easy-to-use health tracker/interface
  • Data contributed anonymously to scientific research at a reputable institution
Cons
  • Entries often stay in pending and baseline/history blocks report generation
  • Unreliable Apple Health integration and sleep tracking; manual sleep logging often fails
  • Registration/activation issues and failed support channels (no confirmation emails/codes, contact form errors)
  • Post-update bugs and instability causing error codes and degraded usability

The app was working ok until two days ago after I updated it. Now all of my info is sitting in the pending area and it will not go through and I keep getting errors. I also am not able to use the “contact us” section on the app for the reporting the issue as I am getting errors .

This app is a great idea and comes from a book supposedly written by the app creator, that has some really good ideas and concepts. The app, however, doesn't generate reports. You get error codes instead. There's also no way to access or download the data. Hence, no workaround. On top of that, about 60 days worth of data just got deleted, going by my "streak" which just reset to 0, despite my using the app daily for about half a year. You'd think the doctor might spend a fraction of his royalties on getting a proper app made.
