Verdict
The clearest difference is review sentiment: KYDZ at 75% against CAR OBD's 0%. KYDZ also leads on in-app purchases (none vs 5) and update cadence (every 10 days vs every 6 weeks). CAR OBD's advantage is rating (5.0 vs 4.1) and iOS requirement (13 vs 15.0). On price, ads and device support 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. KYDZ 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: KYDZ has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of KYDZ'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.
KYDZ ships an update every 10 days, CAR OBD every 6 weeks. The most recent releases landed on September 13, 2026 and August 2, 2026 respectively.
