Half Star, Not One Star! – OBD Auto Doctor Review

After I purchased Korea ELM-327, I had to downloaded a basic app. Everything worked fine between a device and iPhone via WiFi but it did not provided enough information on the screen, very little like 5% or less about air temperature in the engine and room temperature was all I had. Pretty expensive to buy a device and the basic app sucked! Not sure, do I really want to purchase $ 9.99 app? Why do I have to spend the money this and that things?
