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. X100T asks for nothing beyond the download.
CAR OBD holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: X100T has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of X100T'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.
X100T ships an update monthly, CAR OBD every 2 months. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
