Worth every penny!

This, along with the OBD device you need to buy separately (widely available at online retailers) is an amazing solution to determining whats causing your "check engine" light. Consider that a visit to a dealer service center involves not only paying them a shop rate to plug in their $1000+ tool and charge you time and labor to just look at your fault codes (and then more $$ for highly marked up parts and labor), this app gives you the the same info.

If you are a do it yourself kind of person, the fault code may reveal something relatively easy to fix yourself like a battery, ignition coil or O2 sensor replacement. It also could reveal something more serious that requires more expertise to resolve (and allow you to prepare to spend some $$$ to get it fixed by a pro)!

You can also clear the engine light if the fault codes were generated because of an anomaly that isnt a permanent issue requiring any action at all.

Extremely easy to use. Plug in your OBD device (purchased separately), connect your smartphone to the device private wifi, and start reading codes!

I saved hundreds of $$ in the long run when I learned my faults were: ignition coil, O2 sensor and vanos solenoid. I was able to get those parts (new OEM) for about $225 and do 2 of the 3 myself. The other cost me an hour($100) labor from an independent mechanic. Dealer quoted me about $1000 in parts/labor to do those same items!
