I just got my OBDII adapter today and bought the full version of Torque. The gauges are super super nifty, but I don't know if they're accurate. There do seem to be manual correction "multipliers" for just about everything though, which is good.

However, my question would be, why does it matter? Fuel efficiency is not absolute, it's relative. As long as the app can tell you the correct lambda, load, and instantaneous fuel consumption (approximately), who cares about the actual mpg reading? I have my "main screen" set for fuel economy driving, with a bunch of less important indicators in "tiny" size sitting in the corner, and big displays for load, lambda, mpg. Drive so that lambda doesn't dip too far below 1 but load is high whenever possible, watch the mpg gauge in steady state cruise to determine the best course of action.
