Verdict

The call

The clearest difference is rating: OBD2 Car Scanner at 3.8 against OBD Home's 2.9. OBD2 Car Scanner also leads on ratings volume (1.6K vs 51). OBD Home's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OBD2 Car Scanner holds the better App Store score, 3.8 against 2.9. That said, the two scores are not equally well evidenced: OBD2 Car Scanner has 1.6K ratings behind it against 51, so its average is the more settled of the two. Written reviews complicate that: 32% of OBD Home's written reviews are positive against 4% of OBD2 Car Scanner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OBD Home ships an update every 3 weeks, OBD2 Car Scanner every 2 months. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
