Ratings and reviews

Truly an excellent set of diagnostics software. I use an older Bluetooth OBDLink MX dongle on my cars ('99 Sunfire, '01 Contour, and '01 Impala 3800). I can access everything that the computer has access to without any issue (I was amazed that I could access TAP on my Impala, something that used to be only accessible via a $600 Innova scantool). The GUI may not be the most end user friendly, however, it is functional and to the point. I could only ask for the ability to run KOEO & KOER tests.

The app seems to start itself on start up now and I have to force stop it to remove its notifications. The app itself is nice when I use it, which isn't often. I will propably uninstall it if it keeps sending me unnecessary notifications.

Love the app. Functionality is top notch. If you could add some gauges similar to Torque, periodic checks of engine faults, and pid parameter alarms, I would switch from Torque in a heartbeat.
