Verdict
The clearest difference is rating: OBD2 Scanner at 4.6 against YMOBD's 2.9. OBD2 Scanner also leads on ratings volume (1.1K vs 87). YMOBD's advantage is ads (none vs shown) and review sentiment (36% vs 23%). On price, update cadence, in-app purchases and monetization model there is nothing between them.
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. YMOBD sells 4 one-off in-app purchases and OBD2 Scanner sells 6 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
OBD2 Scanner holds the better App Store score, 4.6 against 2.9. That said, the two scores are not equally well evidenced: OBD2 Scanner has 1.1K ratings behind it against 87, so its average is the more settled of the two. Written reviews complicate that: 36% of YMOBD's written reviews are positive against 23% of OBD2 Scanner's, so the app with the better star average is not the one people write more warmly about.
YMOBD ships an update every 5 weeks, OBD2 Scanner monthly. Both last shipped on October 30, 2026.
