Ultimate Car is software that logs and tracks vehicle (car, truck, motorcycle, etc.) repair, fuel and maintenance (oil change, tune-up, brakes, etc.) events that runs on PDAs using the Pocket PC operating system. It records fuel, oil changes, tire repairs, maintenance events and more for an unlimited number of vehicles. Gas mileage history is available at the tap of a stylus. Last Service information, including last oil change, repair, battery, tire, etc., is also available at a tap. Default suppliers for frequently used types allows quick entry. Last mileage entered is remembered for quick entry for the next time. Change filter to only see items interested in, filter on date range and item types. Can update the Pocket Outlook application with a "next scheduled event" based on mileage and driving factors when certain maintenance events are added (like brakes, oil change, etc.).
