Masterdrive is an application that helps you to keep track of car usage for commercial purposes, e.g. to invoice customers.

Masterdrive for iPhone is the mobile companion application for the desktop version of Masterdrive, and allows you to register your drives with a few click while you're on the road. Through synchronization over a wireless network the data entered on the iPhone can be transferred to the desktop application with a single click.

Data entry on the iPhone is simplified through the use of drive templates, or by using the iPhones built-in location services that can find the address from your current location.
