## Review summary

The reviews show that the app often fails to add/connect the device, crashes on launch, and has update and permission issues. Many users report battery drain and privacy concerns from location sharing, with Android Auto/CarPlay support not available. Some reports indicate occasional working scenarios on specific devices (e.g., Pixel 8 Pro) and after certain updates stability improves, but overall reliability is poor.

### Pros

- Device/monitor is detectable by the app and can pair when functioning.
- Some updates reportedly improve stability, reducing crashes on launch (e.g., v1.0.9).
- On some devices (e.g., Google Pixel 8 Pro), the app works as expected.

### Cons

- Cannot add device; step 4 shows a spinning wheel and fails to complete setup.
- App crashes or won't launch; stuck on splash/initial screen.
- Firmware updates fail to install; progress reaches 100% but update stops.
- Excessive battery usage and location permissions cause GPS logging; privacy concerns about sharing location data.
- No Android Auto / CarPlay support or integration.
