# YMOBD vs OBD2 Car Scanner

The clearest difference is rating: OBD2 Car Scanner at 3.8 against YMOBD's 2.9. OBD2 Car Scanner also leads on ratings volume (1.5K vs 87). YMOBD's advantage is ads (none vs shown) and review sentiment (35% vs 4%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. YMOBD sells 4 one-off in-app purchases and OBD2 Car Scanner sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

OBD2 Car Scanner holds the better App Store score, 3.8 against 2.9. That said, the two scores are not equally well evidenced: OBD2 Car Scanner has 1.5K ratings behind it against 87, so its average is the more settled of the two. Written reviews complicate that: 35% of YMOBD's written reviews are positive against 4% of OBD2 Car Scanner's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 weeks. Both last shipped on October 24, 2026.
