# ThinkCar vs ELMCheck

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.

Both are free to download. ELMCheck sells 1 one-off in-app purchase. ThinkCar asks for nothing beyond the download.
