How does it work? In simple terms, we use your accelerometer, GPS, and geofences. When you start driving faster than 15 mph then Taxbot can sense when you are driving and starts tracking you using the GPS in your phone. When you have stopped moving for a period of 5 minutes then Taxbot will end the trip and save it in your queue of trips to be classified. Then you come back later and claim your deductions by classifying the business trips.
