battery monitoring is reasonable, but location tracking is next to useless. in fact it seems to get worse the longer it's used. sitting in the car it tells me I'm in one location but the car appears to still be at home. Totally useless. Sometimes the correct location appears days later which again is not much help.

Works well, mostly. Good enough for my purposes For some reason it will only connect to the BM6 module by turning bluetooth on and off again. But once connected it's a very reliable connection (which is impressive given it lives in an engine bay with spark ignition) and the monitor itself is working great. Trip tracking works well if using another app that keeps the GPS active (eg. Google maps) but otherwise the location data it gets is erratic.

pretty good app and not disappointed. But an improvement would be to allow you to zoom in whilst looking at the day graph.
