Im not one of those that always has to have the latest and greatest, but I needed a new phone BAD
I went with a new carrier and ended up getting a brand new HTC Evo with (get this) "Ice Cream Sandwich" as an operating system
Well anyway as Ive been playing with this thing I found an app called aCar
on the HTC hub (still not sure of a lot of this stuff LOL) but anyway this can track fuel mileage, costs, can be set up to remind you of service needed etc. So I had a service call in Yuma today, about 200 miles one way. I only wish I had thought to take my garmin along to get actual speed. But running an indicated 80 all the way there and then a lot of 85 and 90 coming back I averaged 38.417 mpg Every fill up you enter the data, I even found one pump cheated me by .03 cents overall
(input price/gal and then input total gal. down to .000 and it tells you how much you paid for your gas) So far I really like it. Just thought I would share.
