Wow, I didn't know there was a paid Pro option, but the same developer also makes the open source app Rectangle, which sounds like the same thing minus a few features. I use it daily. https://github.com/rxhanson/Rectangle/
I recently started using the pro version for the custom shortcuts. On a portrait mode monitor I like to split the pane vertically into thirds, so it makes that possible. It's also a pretty cheap buy at $10.
