First used this app in Rio de Janeiro, Brazil. The taxi driver arrived and did not pick up the family, because we were 5 persons. OK, no matter I thought, take another one. But the driver said I have to cancel the order, because of app rules. With this cancellation I had to pay a part of a ride I never did. Scandalized about this behavior I sent an E-mail through the app and reported the app team what happened. To this day I didn't get any response and no refund. So, I cannot recommend this app because, if you get in trouble maybe, there's no help for you and you'll lose your money. One star for this app is one star to much. Don't use it! Danger!
