ClaimableKms logs your business related trips in your vehicle and automatically calculates your tax deduction. You can:
● automatically record trips using the gps
● manually record trip details
● be warned of any incomplete trips
● review the map of any previous trip (help remind yourself of the purpose if you didn't record it at the time)
● record all details required by the tax office
● collate and reports on trips monthly and annually
● save the details of multiple vehicles and set a vehicle as the default

Please note while recording trips,

"Continued use of GPS running in the background can dramatically decrease battery life."
