Verdict

The call

The clearest difference is price: Carista OBD2 at Free against Dip Calc's $0.99. Carista OBD2 also leads on rating (4.6 vs 4.0) and ratings volume (4.3K vs 2). Dip Calc's advantage is in-app purchases (none vs 10) and ads (none vs shown). On device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Carista OBD2 holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Carista OBD2 has 4.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 34% of Carista OBD2's written reviews are positive against 50% of Dip Calc'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, Dip Calc every 8 days. The most recent releases landed on November 9, 2026 and November 3, 2026 respectively.
