Verdict
The clearest difference is rating: CAR OBD at 5.0 against OBD Mate's 1.8. OBD Mate's advantage is in-app purchases (none vs 5) and ratings volume (115 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. CAR OBD sells 5 one-off in-app purchases. OBD Mate asks for nothing beyond the download.
CAR OBD holds the better App Store score, 5.0 against 1.8. That said, the two scores are not equally well evidenced: OBD Mate has 115 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 9% of OBD Mate's written reviews are positive against 0% of CAR OBD's, so the app with the better star average is not the one people write more warmly about.
OBD Mate ships an update every 5 weeks, CAR OBD every 6 weeks. The most recent releases landed on October 16, 2026 and September 16, 2026 respectively.
