# Mobile KD vs CAR OBD

The clearest difference is review sentiment: Mobile KD at 48% against CAR OBD's 0%. Mobile KD also leads on in-app purchases (none vs 5) and ratings volume (59 vs 1). CAR OBD's advantage is rating (5.0 vs 4.6) and iOS requirement (13 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. CAR OBD sells 5 one-off in-app purchases. Mobile KD asks for nothing beyond the download.

CAR OBD holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Mobile KD has 59 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 48% of Mobile KD'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.

Mobile KD ships an update fortnightly, CAR OBD every 6 weeks. The most recent releases landed on October 14, 2026 and September 16, 2026 respectively.
