Verdict

The call

The clearest difference is rating: OBD2 Scanner at 4.6 against BT1's 2.4. OBD2 Scanner also leads on ratings volume (1.1K vs 14) and update cadence (monthly vs every 4 months). BT1's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price and device support there is nothing between them.

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 1.1K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 48% of BT1's written reviews are positive against 23% of OBD2 Scanner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

BT1 ships an update every 4 months, OBD2 Scanner monthly. The most recent releases landed on October 21, 2026 and October 30, 2026 respectively.
