Verdict
The clearest difference is review sentiment: Car Sensor at 100% against OBD2 Car Scanner's 55%. Car Sensor also leads on in-app purchases (none vs 3) and rating (5.0 vs 4.6). OBD2 Car Scanner's advantage is update cadence (every 5 weeks vs every 32 months) and ratings volume (5.1K vs 1). On price, ads and device support there is nothing between them.
