This app has served me well for so long… and continues to do so. I bought premium, as the price is great for value, and functionality (especially logging) is superb. Interface is clean, and easy to navigate. Best OBD reading app for me.
Basic information, error codes and the possibility of reading and deleting them. Check Engine doesn’t scare me anymore. I recommend.
Exceptionally good! This is one of the best OBD II apps. Simple yet very straightforward and efficient! I still have to test the new update but it looks already very good!
In my case, Megane II Station Wagon 1.6 petrol, everything works, Passat B6 2.0 2014 also shows errors without any problems. I personally recommend it.
