## Review summary

The app excels at near-vehicle monitoring with continuous voltage data and easy data export, plus active development and good data merging. However, reliability challenges persist: crashes causing data loss, inconsistent reconnection, and occasional data accuracy issues (SoC vs voltage).

### Pros

- Automatic near-vehicle updates with continuous voltage data logging.
- Data export options to Excel (.xls/.xlsx) and easy sharing.
- Active development with regular app updates.
- Seamless merging of new data with existing data for a long, continuous record.

### Cons

- App crashes and can lead to data loss.
- Reconnection/reliability issues after leaving the device or re-pairing (requires force close or restart).
- Some data readings are inaccurate (e.g., SoC shown as 100% due to reading alternator voltage).
