Horrible

Won't stay connected.. connects then disconnects. This has been an issue with this app going on 2 years. A shame
MGMardis Gras

Works on Android

All the features of this app work on my friends Android but not on my iPhone, it has hard or impossible to use most if not all features. All I can do is look at the trouble codes.

Almost useless

Bluetooth won't stay connected or just never connects. Not sure why this hasn't been fixed.
MGMardis Gras

Limited use application when it works

App doesn’t consistently see connected Bluetooth devise. Limited options for diagnostic. Can’t activate or remotely control engine components for testing

Bluetooth tool will not stay connected

Everytime you open this app it disconnects the Bluetooth from mobile device to diagnostic tool. $500 for the tool and not useful at all.
