Ratings and reviews

Must have app. Especially for those, who want to monitor their element condition. Mine had one weak cell and I was always observing it while driving. Besides it this is very good app to simply look at remaining kilowatts left, temperatures and e.t.c. One known bug(at least on my samsung a7 phone) is if you leave application running on phone, shut down car and return in few minutes, you must restart application, because it can not connect to obd device. Other than that never had any issues. Five star from me.

Not bad, but not perfect. Would be nice if it had a "hold mode" button like the "myvolthold" app, for those of us with early cars that would like to keep the engine off more. Would be cool if it could see deeper into the car, but maybe this isn't possible. Something like being able to see the total EV miles/total gasoline miles, which is no longer possible on cars that can't get OnStar, etc. Does provide some helpful information overall. I The battery cell monitoring and google map drive tracking add ons weren't very expensive, but aren't all that useful - even just a paragraph or two in a readme file about how to use them would be nice to have. Overall, definitely a good app, but I'd love to see some more features!

I really want to review this 5 star, but I can't. This is due to the "Battcell" tab purchase needing to be validated over Internet every time the app is closed and often after it is no longer the foreground app. Internet isn't available everywhere at all times, rendering my purchase feature unusable way too often. Reached out to developer to see what they say about it.

What’s new

Rebuilt app for Android 16
Added battery internal resistance to the BattCell Tab (in-app purchase)
