Odometer Keeper is a program mainly designed for commercial/professional drivers who need to keep track of a vehicles odometer readings when crossing state lines, or when fueling their vehicle. It can be used in any vehicle to keep track of this information, but for the most part, it was primarily designed with the American truck driver in mind. It was also designed for easy use. The program can be set to auto save on exit, so the user doesn't forget to save, and looses information. This also saves extra steps by allowing the user to put in the information and be done with it. No extra buttons to find, no complicated menus. Manual operation of the program is also available for those who like to make sure they know that the software is working correctly, and giving them more control of what information is saved and when.
