I recently came across a couple guys using it to monitor IAT's and other things in lieu of having 40,000 gauges. I bought the app $5 and a $25 bluetooth OBD2 adapter. It can read codes as well and link with your navigation apps to plan out routes and so forth.
I can view things like instant MPG, compass, have a supplemental speedo and tach as well as other things. It can datalog, calculate HP and Torque (although I have no clue what my car acutally weighs..but it is all pretty customizable and that.
I just thought it was cool to have and I will probably be getting a RAM mount for my phone so I could play with the 0-60 and quarter mile times on my car
