Verdict

The call

The clearest difference is rating: Carista OBD2 at 4.6 against OBD2 Trouble Code's 3.3. Carista OBD2 also leads on ratings volume (4.1K vs 306) and chart position (#150 vs unranked). OBD2 Trouble Code'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 3.3. That said, the two scores are not equally well evidenced: Carista OBD2 has 4.1K ratings behind it against 306, 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 OBD2 Trouble Code's, so the app with the better star average is not the one people write more warmly about.
