# X100T vs CAR OBD

The clearest difference is review sentiment: X100T at 100% against CAR OBD's 0%. X100T also leads on in-app purchases (none vs 5) and ratings volume (11 vs 1). CAR OBD's advantage is rating (5.0 vs 4.2). 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. 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.
