## Review summary

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
