TorqueBot vs Carly: Which AI Car Diagnostic Tool is Better?

Carly is one of the more established OBD2 scanner apps on the market. It combines a physical Bluetooth scanner (which you buy separately) with an app that reads codes, runs diagnostics, detects odometer fraud, and even lets you code certain vehicle features. It's well-regarded in the BMW and European car community. The downside is you need their hardware, and the subscription cost adds up on top of the scanner purchase.
