User Reviews

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).

Recent reviews

I have used this device for over one month. I had trouble auto-pairing only once, but that was probably user error. The device auto pairs if you walk next to the car and just wait for a while. The app seamlessly fetches new data and merges it with data that is already on the phone, so you get a continuous record of voltage every two minutes for as many days as you want. I AirDrop the exported .xls file onto a Mac and look at it with Numbers. A comma-delimited “.csv” plain text file would be a more flexible option for just the voltage, SOC, and temperature data. However, the report has several separate tables, so an .xls file may be necessary. I do not like their privacy policy because they collect (and almost surely sell) GPS assisted trip information tied to the serial number of your device. I have set the iPhone Settings (not the app Settings) to not allow GPS for this app, which disables the trip and find your car “features”. The voltage data logging, which is all I need, still works perfectly. Five stars if they change their privacy policy.

I’m not sure why this app has a low rating – it does everything it’s supposed to and works great for me at least! Every time I walk by my vehicle, the app updates and keeps me apprised of the state of my battery, which is exactly what I’m looking for. The developer updates the app regularly so I’m not sure what more we could ask for – thanks for a great app!

I don’t know why others have had so many problem but this App works great for me. Whenever I walk by the car the app updates. Maybe they aren’t hanging around long enough? It gives me all the data I’m looking for and I can export it out as an xlsx file and email it to myself. Great info. I’m really impressed.
