Yeah, but you couldn't have done any of that without the app. At best, you could have done it all on a web page accessible by a regular PC, but that wouldn't have gotten anywhere because who's using a desktop/laptop PC while they're standing on the street looking for a ride? Having an app that runs on a portable communications device in your pocket made all those things (hailing, payment, ratings, etc.) possible to do.
