For what it is it's pretty good! I've got the Li version and my biggest gripe is the scale of the voltage graph. As most of its life it sits between 12 and 14 volts, it would be useful if we could scale in the graph. Even better, if it was dynamic so only showed voltages that had been detected. Also, Li doesn't need a crank test and it would be good to manually start and stop a trip! Still, great unit for the price and I think they're a pure Ozzie outfit. Edit - 2 star as % for LifePo4 is wrong

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.
