ReceptionRating · Positive reviews · Number of ratings

OBD2 Scanner holds the better App Store score, 4.6 against 2.4. That said, the two scores are not equally well evidenced: OBD2 Scanner has 974 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 23% of OBD2 Scanner's written reviews are positive against 29% of MAXOBD's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OBD2 Scanner ships an update monthly, MAXOBD every 3 weeks. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
