# OBD2 Car Scanner vs ELMCheck

The clearest difference is review sentiment: ELMCheck at 100% against OBD2 Car Scanner's 55%. ELMCheck also leads on rating (5.0 vs 4.6) and update cadence (every 10 days vs every 5 weeks). OBD2 Car Scanner's advantage is ratings volume (5K vs 1) and iOS requirement (14.0 vs 18). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. OBD2 Car Scanner sells 3 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 4.6. That said, the two scores are not equally well evidenced: OBD2 Car Scanner has 5K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 55% of OBD2 Car Scanner's written reviews are positive against 100% of ELMCheck's.

OBD2 Car Scanner ships an update every 5 weeks, ELMCheck every 10 days. The most recent releases landed on September 24, 2026 and September 16, 2026 respectively.
