I use Driversnote to keep track of my kilometers driven, which helps me distinguish between business and personal use and calculate expenses for tax deductions. It's simple, and I really like my inbox where I can quickly classify trips as business or personal on the main screen; it's almost like a game to me when it's late at night and I'm watching some TV. I can see all my trips that I haven't reviewed yet and ensure they've been classified correctly! The initial setup was very easy and quick. Review collected by and hosted on G2.com.
I would love to see Location-based classification since my trips classification depends on that. It would be nice to set all trips from/to a destination as either business or personal since my work schedule isn't set in stone like a 9-5pm and all trips within are business.
