ELMCheck offers a comprehensive set of test cases that cover the entire documented set of ELM327 commands. Regardless of which version your scanner says it is, ELMCheck can provide a comprehensive report of the features that are actually supported.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 23, 2026 and September 16, 2026 respectively.
