# OBD JScan vs ELMCheck

The clearest difference is ratings volume: OBD JScan at 1.3K against ELMCheck's 1. OBD JScan also leads on iOS requirement (13.0 vs 18). ELMCheck's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 79%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

ELMCheck holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OBD JScan has 1.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 79% of OBD JScan's written reviews are positive against 100% of ELMCheck's.

OBD JScan ships an update every 3 weeks, ELMCheck every 10 days. The most recent releases landed on September 24, 2026 and September 16, 2026 respectively.
