In many beginner JS tutorials, the end goal is to build an app of some sort, and they are frequently of a similar type: todo lists, stopwatch timers, pared down clones of common social media apps, etc.

There's obviously good reason for this - when you don't have to expend too much mental energy understanding what you're building, it's easier to understand how. They are also limited in scope, which makes them more manageable.

However when I was working through many of this type of tutorial a few years back, I've got to admit that I sometimes found myself getting a little bored...

So I'm interested to hear from the beginners out there - ignoring any issues of difficulty or complexity - what kind of app would you want to build in a project style tutorial?
