If people want to know what is around them they might use Yelp app, if people want to share something with friends they might use Facebook or Twitter app, if people want to book a flight they might use Kayak app, if people want to listen to music they might use Spotify or Pandora apps, etc. Nobody waits until they get back home from wherever they are and turn on their computers to do all of the above. As well as nobody thinks to use just a responsive version of those applications on their mobile. People want efficient and beautiful native mobile applications that would instantly connect them to the world.
