Verdict

The call

The clearest difference is rating: OBD2 Scanner ELM327 at 4.3 against VAG Coding's 3.6. OBD2 Scanner ELM327 also leads on ads (none vs shown) and ratings volume (25 vs 5). VAG Coding's advantage is in-app purchases (none vs 24) and review sentiment (79% vs 46%). On price, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OBD2 Scanner ELM327 holds the better App Store score, 4.3 against 3.6. That said, the two scores are not equally well evidenced: OBD2 Scanner ELM327 has 25 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 46% of OBD2 Scanner ELM327's written reviews are positive against 79% of VAG Coding's, so the app with the better star average is not the one people write more warmly about.
