- GPS-recorded trips can be interrupted and resumed for phone calls or other apps.
- Flexible data entry includes odometer start and stop readings.
- The "smart" odometer starts each new entry with the last highest-used value.
- The "Favorites" feature makes entering recurring entries quick and easy.
- Customizable categories allow for multiple clients and billing codes.
