My Samsung Galaxy S21 complains about this app "overloading the system" every day when it's not even in use. It'll hit 25% CPU utilization. Maybe it's the periodic report feature that does that. If so, it should do the work incrementally and break it apart into small chunks so it doesn't hit the processor hard like this. I just want a simple app that reads error codes and tracks car activity automatically. Hopefully this will be fixed. Then this would be a five star app.

There are many good OBD apps available, but OBD Mary is just a bit better than the rest. Better UI, better features, better performance. I especially like how much better the free version is than the free versions of the other OBD apps. You don't "need" to upgrade from the free version, but if you can, you should! My 2012 Mazda is starting to show it's age, and I wanted to more closely monitor its performance and also check the error codes that occasionally pop up then go away.

Handy app but buggy. Nice options for gauge design and lots of customization options. But paid version still shows ads, and keeps reloading the dashboard over itself. Some gauges show zero or NaN after a while, then you have to reconnect. Screen doesn't always fit properly so some info ends up behind the top bar or interface buttons. Keeps trying to connect after car is off, killing battery unless force closed. Still probably the best ELM scanner I've used, but could be much more polished.

Best, mostly free app to pair with an OBD scanner in a car. Tried a few apps and this one gave the most functionality for free and has a lot of features in the full version. Even the price to get the full version is very reasonable compared to the other apps available and I'll likely be paying for that very soon!

works but for fuel rail pressure it's in Pa with 7 decimal places and e7 so off screen and unreadable. Lazy coding, like measuring NY to LA in inches. kPa, MPa or Bar with just 1 or 2 decimals would be better. Nevertheless it connected up where other apps wouldn't.

Stupid ad. got to shut and restart the program, when the ad jumps on screen. With these prices I'll rather go and buy an OBD device and don't use any Android program.
