"Beautiful" maybe, not "good UX" for sure. Prior to Uber, calling a cab using the phone app was...suboptimal and easier to actually call a taxi company. They also provided much better services, which is what make them stick around.

RH made a lot of investment tool accessible to people that "I just want to buy stock of some company", I used tasty trades for a while, but their mobile app while has all functionality, but realistically you will just look to overview portfolio.
