## Review summary

Users praise the radon monitor hardware and appreciate the app's functionality in providing radon readings quickly and logging data over time. However, multiple users report connectivity issues with Bluetooth, limited data visualization lacking date/time references, app stability problems including frequent crashes, and insufficient customization options. While updates have fixed earlier problems, the app would benefit from a better user interface, improved stability, and enhanced data handling features for long-term use.

### Pros

- Provides radon level readings including peak, average, and current values.
- The hardware (radon monitor) is of good quality and considered reliable.
- Bluetooth connection works well for some users, enabling data transfer from the device to the app.
- Firmware and software updates have improved functionality and connectivity over time.
- Gives readings within an hour and supports long term data logging (thousands of hours).

### Cons

- The app frequently fails to connect or loses connection with the device via Bluetooth.
- Data visualization is limited; charts only show hours without date/time stamps, making multi-day analysis difficult.
- The app crashes often and requires restarting or reloading after Android updates.
- Lack of adjustable settings such as file storage location and poor English translation in instructions.
- Firmware updates sometimes fail, and the app sometimes requires forgetting the Bluetooth device and reconnecting to work properly.
