# Carista OBD2 vs OBDocker

The clearest difference is rating: Carista OBD2 at 4.6 against OBDocker's 3.9. Carista OBD2 also leads on ratings volume (4.3K vs 17) and chart position (#155 vs unranked). OBDocker's advantage is ads (none vs shown) and review sentiment (47% vs 34%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Carista OBD2 sells 6 in-app purchases, starting at $19.99 per month and OBDocker sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Carista OBD2 holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Carista OBD2 has 4.3K ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 34% of Carista OBD2's written reviews are positive against 47% of OBDocker's, so the app with the better star average is not the one people write more warmly about.

Carista OBD2 ships an update every 3 weeks, OBDocker fortnightly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
