# Carista OBD2 vs Mini OBDII

The clearest difference is rating: Carista OBD2 at 4.6 against Mini OBDII's 3.7. Carista OBD2 also leads on ratings volume (4.3K vs 10) and chart position (#170 vs unranked). Mini OBDII's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. Carista OBD2 sells 5 in-app purchases, starting at $19.99 per month. Mini OBDII asks for nothing beyond the download.

Carista OBD2 holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Carista OBD2 has 4.3K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 34% of Carista OBD2's written reviews are positive against 38% of Mini OBDII'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 3 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
