Nice idea, but app doesn't work. I tried it a few times on different phones in the past 12 months. It works for less than one minute, then crashes.

by Donald the 4/27/2011

Has great potential. But shows unrealistic mileage so far. Will have to play with it more.

by jarrod the 4/26/2011

It works but states my 4wd hemi ram gets 40+ MPG instant and over 35 average.

by earthling the 4/10/2011

Dev isn't updating paid app as frequently as free one! Doesn't reply to emails. :-(

by Toastee the 4/6/2011

No option to prevent phone from sleeping, makes this useless as a dashboard app

by Jerry the 3/30/2011

Great potential. Needs to update the average mpg consistently and ability to toggle screen timeout. Nice app already though. Worth the download.

by Julian the 3/16/2011

Yay! Metric units! Now this thing is dripping with potential!

by Ian the 3/15/2011

Looks promising with one issue so far The average MPG stays at 0 whilst the Immediate MPG works. Also, any possibility of adding more PIDs?

Thanks! Looking good on HTC Hero
