Very useful productivity tool.

This app is very useful when you want to just focus in on one app, while having other windows dimmed (but still visible).

One might argue that it is more useful to just fullscreen an app (which it is for some circumstances), however I have found some situations in which I prefer using HazeOver.

* You would like to clearly see which of your current windows is active. Some people like to juggle many windows on a single workspace at once, and I could see this being useful to quickly identify which window you are currently focused on (to avoid mistakes like entering data in another window besides the one you are looking at)

* You would like to work with multiple windows side by side, but focus on one at a time. This is very useful when you have another document open for referencing while you are working on something else primarily. You just set the dim transparency to be at a reasonable level so that you can still see the reference documents, but at the same time focus on your primary window.

* You don’t like working with apps in fullscreen, but still want to isolate your working window. I personally don’t like working with certain apps while I’m fullscreen, such as an internet browser. On my 27” display, there is too much empty space when viewing a lot of webpages. I prefer to instead size the internet browser window to a resonable size for most webpages, and use HazeOver to dim everything else in the background.

Another app that is free that offers the same functionality (Isolator), however it doesn’t seem to be updated any more.
(It should be noted that Isolator is under the MIT License and source code is on GitHub if you’re interested)

Since I bought HazeOver, I’ve had no complaints and it’s been a step up from Isolator in the smoothness and user experience department.
It is one of the more polished and frequently updated apps I have purchased on the Mac App store.
