I guess it is just a taxi calling app, but I have to say that for me personally, Uber has become a very useful tool because I can just instantly get wherever I need to go whenever I travel to a new place I've never been before. I hardly ever use Uber in my home city, but when I travel I use it all the time. That kind of stuff used to involve a bunch of planning, now I just open an app and I immediately get a decent estimation of time needed and price to get to my destination, all over the world. I don't find it so surprising that there is a bunch of complexity involved there.
