My only addition to what Meron35 said is that Launchers can provide interfaces that both look and act differently than the built-in launcher. Some of them are radically different from the default, with everything from expanding radial menus to an actual command line. There is not single best solution that suits everyone, so Launchers allow you to decide what experience works best for you.
Basically the home screen. Third party launchers used to be the frontier of introducing new features, like gestures, app drawer categories, different icon layouts like more columns/rows, customer icon theme packs, custom animations, etc.
The iOS equivalent if you jailbroke was SummerBoard/WinterBoard, a pun on SpringBoard (name of iOS launcher).
What even is a launcher, what does this app actually do? I’m asking earnestly I’ve never been able to figure it out
