# OBD2 Car Scanner vs YMOBD

The clearest difference is rating: OBD2 Car Scanner at 4.6 against YMOBD's 2.9. OBD2 Car Scanner also leads on ratings volume (5.2K vs 87) and review sentiment (55% vs 36%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

OBD2 Car Scanner holds the better App Store score, 4.6 against 2.9. That said, the two scores are not equally well evidenced: OBD2 Car Scanner has 5.2K ratings behind it against 87, so its average is the more settled of the two.
