Verdict

The call

The clearest difference is rating: Carista OBD2 at 4.6 against MX5 Tech Remote's 3.2. Carista OBD2 also leads on update cadence (every 3 weeks vs every 12 months) and ratings volume (4.2K vs 21). MX5 Tech Remote's advantage is in-app purchases (none vs 14) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Carista OBD2 holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: Carista OBD2 has 4.2K ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 34% of Carista OBD2's written reviews are positive against 37% of MX5 Tech Remote's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Carista OBD2 ships an update every 3 weeks, MX5 Tech Remote every 12 months. The most recent releases landed on October 22, 2026 and October 17, 2026 respectively.
