# Code vs OBD JScan

The clearest difference is rating: OBD JScan at 4.7 against Code's 4.0. OBD JScan also leads on ratings volume (1.3K vs 5). Code's advantage is iOS requirement (10.0 vs 13.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Code sells 1 one-off in-app purchase and OBD JScan sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

OBD JScan holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: OBD JScan has 1.3K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 75% of Code's written reviews are positive against 80% of OBD JScan's.

Code ships an update monthly, OBD JScan every 3 weeks. The most recent releases landed on October 1, 2026 and October 11, 2026 respectively.
