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.

Surprised that coming out of the Salk Institute this app would be so archaic and not user friendly. I’m sensitive to nnEMFs yet using this app forces me to connect to the Internet for every activity logged. Oura Apple Garmen and several other tracking devices record and store data and allow the user to log data while not connected to Bluetooth, WiFi or cellular data. This is a non negotiable for me, having to wake up turn on my WiFi and stare at blue light from the screen before I get outside for sunrise? This app would make me more sick!
