Must have for any auto enthusiasts
You need to get the BlueDriver dongle($99) to be able to use all the features of the app. That being said, together the app and dongle give you all the information you get from a good handheld scanner unit. ABS, Brake, and every other light can be diagnosed. Most apps and dongles are limited to just check engine lights. It is simple to use and accurate. The price of the BlueDriver hardware and software are cheaper than a scanner that supports ABS and OBD2 diagnostics. I recommend this to any backyard mechanic looking for a good scanner at a good price.
