Ratings and reviews

Would be great if it didn't continually crash, actually kept logs etc. Kinda pointless when you go into battery history to check how efficient the solar panels are working and the graphs are full of blanks! For a paid app, I would expect far more. Zero customer service, have asked several times for a bug fix to stop the continuous crashes and missing information. Would rate zero stars if that was an option!

I decided to buy this app in spite of the reviews as I have three cars that I want to monitor the batteries on. My review will be in two parts the first with a Samsung S20 and the second with a Samsung S8. S20 monitors 4 batteries but doesn't auto-connect, so every time you get within range you have to manually reconnect to a particular monitor. I think it would only allow one monitor to be connected at a time. The trip feature doesn't work, it records journey time but not route or distance (and yes I had enabled location). Rating about 2 stars as it does at least measure the voltage from multiple monitors but you have to keep reconnecting manually. S8 App auto connects to multiple monitors when they are in range and as you can bind monitors to a particular slot they are your monitors. Trip records route and distance.correctly 5 stars If you want to use this app with a modern phone S9(?) onward I wouldn't recommend it. However if you have an old phone around that you are happy to use then it works really well.

I have a Jeep JKU with a dual battery system installed and I use this app with two monitoring devices to keep track of the battery levels. See problems listed below: Major Problem: BM3 doesn't allow you to BLOCK other sensors you don't own. Other sensors automatically fill up your slots. Please fix! Problem #2: BM3 won't run in LANDSCAPE mode. If you have a tablet or Android head unit it will immediately crash. Developer stated problems would be fixed in next version and this hasn't happend.
