# Code vs OBD2 Scanner

The clearest difference is review sentiment: Code at 75% against OBD2 Scanner's 23%. Code also leads on ads (none vs shown) and device support (3 vs 1). OBD2 Scanner's advantage is rating (4.6 vs 4.0) and ratings volume (974 vs 5). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Code sells 1 one-off in-app purchase and OBD2 Scanner sells 6 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

OBD2 Scanner holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: OBD2 Scanner has 974 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 75% of Code's written reviews are positive against 23% of OBD2 Scanner's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 12, 2026 and October 17, 2026 respectively.
