Magnet for macOS
Activated by dragging, customizable keyboard shortcuts or via menu bar, Magnet declutters your screen by snapping windows into organized tiles.
Although macOS Sierra has a great split-screen option* that rival’s Windows 10 snap-to-side feature I’ve always wanted a bit more control. This utility is currently only a dollar and does a lot more.

* To activate split-screen view on macOS: make an app full screen, then drag the second app you’d like up into the menubar and place it on top of the other full screen app. Here is a video. It isn’t very intuitive but it is nice that it exists. I think Windows 10’s feature is a bit easier to discover by dragging to the edge of the screen.
