# Car Sensor vs OBD JScan

The clearest difference is in-app purchases: Car Sensor at none against OBD JScan's 8. Car Sensor also leads on rating (5.0 vs 4.7). OBD JScan's advantage is update cadence (every 3 weeks vs every 32 months) and ratings volume (1.3K vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. OBD JScan sells 7 one-off in-app purchases. Car Sensor asks for nothing beyond the download.

Car Sensor holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OBD JScan has 1.3K ratings behind it against 1, so its average is the more settled of the two.

Car Sensor ships an update every 32 months, OBD JScan every 3 weeks. The most recent releases landed on October 1, 2026 and October 16, 2026 respectively.
