Actually yes. You're emailed a receipt with a map that includes the route you took. If you have any complaints, you can email them and they'll usually adjust your rate.

(I don't know if that's a formal guarantee but it's my experience)

This dispatch app IS the gps. If it doesn't work they don't get jobs/paid.

Also you generally enter your destination into your phone before ever getting in the car. The company usually knows which account holder is riding, who is driving, which car, and where they're all going at the time the ride begins.
