Verdict

The call

The clearest difference is in-app purchases: GS at none against Carista OBD2's 13. GS also leads on ads (none vs shown). Carista OBD2's advantage is ratings volume (4.1K vs 316) and chart position (#166 vs unranked). On price, rating, review sentiment and update cadence there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Carista OBD2 holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Carista OBD2 has 4.1K ratings behind it against 316, so its average is the more settled of the two. Written reviews complicate that: 36% of GS's written reviews are positive against 34% of Carista OBD2's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GS ships an update fortnightly, Carista OBD2 every 3 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
