| If you want... | Recommendation | |----------------|----------------| | Free & easy | Use a basic OBD2 scanner app (Torque, Car Scanner) — but no programming. | | Professional programming | Pay for GM Techline Connect (now ACDelco TDS).

Bottom line: You can download GM Techline Connect for free, but using it fully requires a paid subscription. For safety, reliability, and genuine functionality, the paid version is unequivocally “better” than any cracked or free clone.
