The two stars were only because the App was working very good until the day I reviewed this. I booked a cab and it showed that the driver accepted my request, but the driver said he was unable to start the trip due to app issues. So I had to book a second one, and he reached the location but when he tried to start the trip by typing the PIN, the trip was not starting even after several attempts. I was lucky to not pay cancel fees but I request Uber to rectify their app related issues.
