Pretty bad. Extremely buggy, disconnects from the vehicle if you use a different app for 5 seconds or turn off your phone screen, constant problems showing PIDs, now even pulling a door code doesn't work. Every vehicle only shows 4 numbers, not even in the right order.

It will not let me log in!!! I put the code in my email and only an error code. I was initially looking for Forscan. This app is a waste.
