## Review summary

Reviews are mixed to negative. Users like the app’s ease of use and find it usable when devices stay connected, but widespread issues dominate: unreliable Bluetooth connectivity, frequent crashes and logouts, updates breaking features (with requests to rollback), incorrect or missing readings and diagrams, and login/sign-in hurdles. Fieldwork is hindered by offline/login frictions and multi-device usage problems. Overall sentiment is frustration with reliability, despite occasional positive performance when connections hold.

### Pros

- Easy to use / intuitive UI
- Works when connected to compatible devices
- Useful for HVAC/refrigeration measurement workflows
- Positive basic usability feedback (e.g., 'It works', 'good')

### Cons

- Frequent Bluetooth connectivity problems and inability to connect to devices
- App crashes, instability, and constant logouts
- Update-related issues: forced updates and breakage after updates; rollback requested
- Data display problems: readings not shown or incorrect, diagrams misrendered, and settings not saved
- Login/sign-in issues hindering calibration and use
