The Mileage Tracker uses some ever so clever GPS techno smarts to track your trip mileage and export it via CSV spreadsheet format or into Google Earth. You can use it to accurately trace your distances for business expenses, tax deductions and other useful purposes. The thing supports three languages and kilometers or miles and will store the times and distances for multiple trips. Clever. No price as yet, although the site does say there will be no monthly charges involved.
