Ratings and reviews

Edit: New version has fixed the problems. Working well again. Update broke the app. Bring back the previous version. Will connect once and then shutdown, won't connect after that until it is killed and restarted. Has the current device address but will not reconnect to it. Reinstalled and set permissions, still does not work.

I think it is about time someone reviewed this app so that other people would get to know about it. I am lucky enough to own a few vehicles and, over the last year or so, they have spent a lot of their time not moving. This app, combined with the battery monitoring hardware (around £20 or so) enables me to monitor the battery health of each vehicle. It also provides information on charging performance and has even alerted me to a possible issue of low cranking voltage. I recommend this app.

The UI is really clunky if you have more than 1 unit monitoring your system. I have a one on my crank battery and another on my lithium second battery. There is no way to monitor both of them at the same time and changing between units is slow and not user friendly. Please consider this in subsequent updates. Thanks.
