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. Get the confidence you need to use your OBD-II scanner on your vehicle safely. ELMCheck is free to run basic tests. An in-app purchase will unlock the full test suite.

Verdict
The clearest difference is review sentiment: ELMCheck at 100% against ThinkCar's 37%. ELMCheck also leads on rating (5.0 vs 2.8) and update cadence (every 10 days vs monthly). ThinkCar's advantage is in-app purchases (none vs 1) and ratings volume (49 vs 1). On price, ads and device support there is nothing between them.
