Verdict

The call

The clearest difference is rating: OBD JScan at 4.7 against Scrap Science's 4.3. OBD JScan also leads on ratings volume (1.3K vs 3). Scrap Science's advantage is review sentiment (100% vs 80%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. OBD JScan sells 6 one-off in-app purchases and Scrap Science sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

OBD JScan holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: OBD JScan has 1.3K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 80% of OBD JScan's written reviews are positive against 100% of Scrap Science's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OBD JScan ships an update every 3 weeks, Scrap Science every 2 weeks. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
