Customer Reviews

Scam, scam, scam

This is a scam to buy proprietary hardware. I would rather they charge $2 and let me use standard wifi connection to OBDII compliant hardware. They are not upfront about this proprietary hardware and waste my time trying to connect with weird wifi settings.

Don't waste my time with proprietary crap that doesn't work with standard hardware.

Um well.. Almost lost my car

I plugged it up to the ecu with a obd2 cord that I use with my tuner. It's made for an iPhone an it still works properly with my tuner. BUT THIS APP ALMOST CAUGHT MY CAR ON FIRE. The cord was to hot to even touch and it was just trying to read my car. I guess get this app if you want to lose your car.

Not this one, it's a waste of time

The proprietary hardware is not available. The Developer Website link is zeroed out.
