ReceptionRating · Positive reviews · Number of ratings

BlueDriver OBD2 Scan Tool holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: BlueDriver OBD2 Scan Tool has 14K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 57% of BlueDriver OBD2 Scan Tool's written reviews are positive against 67% of miTrail's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

BlueDriver OBD2 Scan Tool ships an update every 9 days, miTrail every 2 weeks. The most recent releases landed on September 25, 2026 and July 7, 2026 respectively.
