# CarKeeper＋ vs OBD2 Car Scanner

The clearest difference is in-app purchases: CarKeeper＋ at none against OBD2 Car Scanner's 3. CarKeeper＋ also leads on ads (none vs shown) and rating (4.0 vs 3.8). OBD2 Car Scanner's advantage is ratings volume (1.3K vs 1). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. OBD2 Car Scanner sells 3 in-app purchases, starting at $4.99 per 7 days. CarKeeper＋ asks for nothing beyond the download.

CarKeeper＋ holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: OBD2 Car Scanner has 1.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of CarKeeper＋'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.

CarKeeper＋ ships an update every 6 weeks, OBD2 Car Scanner every 5 weeks. The most recent releases landed on October 17, 2026 and October 21, 2026 respectively.
