Gassy Girl is a simple gas mileage tracker and reporting tool that I developed for myself. I carry my phone around with me, take just a couple of minutes to fill in an entry whenever I fill up my car's tank, and thus have a nice history of when I've gotten gas, as well as what my car's mileage has been.
