Verdict
The clearest difference is in-app purchases: موسوعة أعطال السيارات OBD 2 at none against Carmin's 2. موسوعة أعطال السيارات OBD 2 also leads on ads (none vs shown) and rating (4.5 vs 4.3). Carmin's advantage is update cadence (every 5 weeks vs every 28 months) and review sentiment (55% vs 43%). On price, device support and iOS requirement there is nothing between them.

موسوعة أعطال السيارات OBD 2 holds the better App Store score, 4.5 against 4.3.

Written reviews complicate that: 43% of موسوعة أعطال السيارات OBD 2's written reviews are positive against 55% of Carmin's, so the app with the better star average is not the one people write more warmly about.
