i would be lying if i say i don't use IOS but be absolute clear that i don't pay for it. if it wasn't work who's in love with APPLE, i wouldn't even touch it. HOw do you like the new IOS 7?
anyway - all of these ELM OBD-II Bluetooth have the same functionality, and they do work. yes sometime you will get a dud like with everything from CHINA but again, you're buying on Amazon and the product is less than the cost of a lunch.
