Verdict
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.

Both are free to download. inCarDoc OBD2 Car Scanner sells 1 one-off in-app purchase and OBDLink sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
OBDLink holds the better App Store score, 4.8 against 3.1.

inCarDoc OBD2 Car Scanner ships an update every 3 weeks, OBDLink every 2 months. Both last shipped on November 6, 2026.
