alt Hacker NewsI don't want to justify the space too much, but things like the Uber app are kind of amazing.
While the base functionality is fairly simple in terms of find location > send car + all the courier and different varieties of what they do. It manages do that while working in 70+ countries over 15,000 cities with multiple different languages and payment vendors and it is all done via a single application.
That is pretty neat.
Yes, it is still very bloated but it does a lot more than what it initially looks like.
But yes, I am endless impressed when you come across a binary that is tiny. Like a text editor that is 14KB, sure it is simply but it doesn't need to be anything more for most people.

Because it's all just API's?
The app just calls the GeoLocation API on the device, pings that off to a server and the server responds with services available in <distance>

I'd assume almost all of that is done server side though. Most likely the app is mostly just a wrapped website with some gps and notification code on top.
