Only works with Android phones. I gave it as a gift and when the person needed it, she opened the package and only then found out it wouldn't work with her Iphone. Great idea for someone with an Android.
Great product! Easy to use, don’t have to anything extra its a plug and play device especially good if you have a check engine light on and want to figure out what exactly the problem is or just clear it and see if it comes back and if you are tuning your car and would like to see the exact rpms, engine load or your 0-60 speed etc. One thing I have to mention that this device IS NOT COMPATIBLE WITH IOS. Overall would recommend it.
