11-2014: PLEASE UPDATE FOR IOS 8!
Im a total numbers geek who also loves my car. Im slightly obsessive about keeping track of my mileage, so Ive been using a Palm OS program for a long time (over 6 years, through 2 cars). When I made the switch to the iPhone, this was one of the transitions I was looking to make immediately. I looked at several of these mileage apps, and initially chose a different one. BIG disappointment. I got rid of that, and tried AccuFuel next. Second times the charm. :)
Im happy with it so far. It does what it says it does, I can edit past entries, and see trends. Id like to see more graphs in the future, but for now, its well worth the time and money. I entered information going back 8 months to get a feel for the app, and also get a baseline for my car going forward (I told you--geek here!). The interface was intuative, and entering all of that data took just seconds per entry, while keeping track of all relevant data.
I highly recommend AccuFuel, for info/car geeks and the casually interested alike.
