Useless without paying $20 – Carista OBD2 Review

You can use this "free" app to scan and it will tell you that yes you have a code on your car but you have to pay $20 for them to reveal the number of the code. There are other apps out there that will tell you the code number and then you can simply Google it. Don't waste your money.
