Verdict
The clearest difference is rating: CAR OBD at 5.0 against PairMyKey's 4.1. PairMyKey's advantage is in-app purchases (none vs 5) and review sentiment (33% vs 0%). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. CAR OBD sells 5 one-off in-app purchases. PairMyKey asks for nothing beyond the download.
CAR OBD holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: PairMyKey has 282 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of PairMyKey'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.
PairMyKey ships an update weekly, CAR OBD every 6 weeks. The most recent releases landed on September 21, 2026 and August 2, 2026 respectively.
