Convenient but beware of inaccurate DTC's and PID values. Great for BMS reset and Key Programming.

signed up for an account, but says I don't have a subscription. couldn't even get to the point of trying to connect to my odb connector. just get andobd, it's actually free and works great unlike all these apps that bait and switch and want a credit card to just read your car's error codes
