Verdict

The call

The clearest difference is rating: OBDLink at 4.8 against inCarDoc OBD2 Car Scanner's 3.1. OBDLink also leads on ads (none vs shown) and ratings volume (13K vs 156). inCarDoc OBD2 Car Scanner's advantage is update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
