Moom is the window manager that helps you meet your deadline

Moom is the name of an app that may save you a lot of window resizing, moving and organising on your Mac. Moom allows you to resize, zoom, move and organise Finder and apps’ windows exactly — and I do mean exactly — per your needs.

Forget about windows management apps in the App Store that cost something like €1.5. Those only contain a list of preset windows with no customisation whatsoever. When I use Final Cut Pro X or Logic Pro X, or when I’m subediting, I have about four to six apps and/or windows open simultaneously. Some of those I cannot hide as the developer hasn’t incorporated standard macOS functionality throughout their application. The end-result is that I lose time over figuring out where a window is that I need at any given moment.

Deadlines hate chaos on the macOS desktop.

A couple of days ago, I came across Moom. Moom costs €10.50 and it’s 100 times more efficient and effective at solving that chaos. Moom offers presets, but it also lets you create and save your own sets of neatly organised windows. It pops up its menu from the green window control icon after hovering over that control for a split second.

Moom is based on a grid that you can fine-tune. It works with multiple displays. Its customisation feature lets you create presets for resizing and moving windows — and doing both simultaneously. It may sound silly when referring to something as simple as a window manager, but Moom’s very powerful. For example, if you create a preset for resizing, you select to resize from nine window anchors, including from the centre outwards. With a key modifier, you can make that preset to resize and instantly move the window to the macOS screen centre. The grid allows you to move and resize windows in organised increments, so if you want your window to be at the edge, that’s fine, but if you want it to be one tile away from the edge, that’s possible too.

A great way to immediately move and resize a window to your needs is to enable the Full Screen or Hexagonal grid feature. If you do that, the popup menu will now show your presets as well as a hexagonal grid (if you’re interested to know about why it’s hexagonal, try Moom and read the Help file; it gives a good insight in how intrusive Intellectual Property Rights in the US have become). Now, when you hover with your mouse over the grid, several nodes will light up. Holding down the mouse until you’ve highlighted the nodes you want the window to move to and resize to will make that happen as soon as you let go of the mouse button.

You’ll never resize and move a window that quickly and effortlessly!

Now, truth be told, even with Moom’s grid-based custom sizes and moves — which do account for probably some 90% of most users’ requirements — I still couldn’t get all of my windows organised exactly the way I always want them for optimal efficiency when I’m editing. For example, I always keep one window close to, but not flush with, the right edge of the screen. At first sight, it looked like Moom wasn’t going to enable me to arrange all these windows at once exactly the way I need it for every subediting job I manage.

And then I found the “Arrange Windows” custom layout. At first, this custom layout looked like it was only going to be interesting in those cases where I have two or more displays hooked up to my Mac. But I soon found out that it allowed me to just place my windows where I want them and then hit the “Save Snapshot” button. From then on, you can just select that snapshot and have all of these windows where you want them – it’s repeatable with one click or keyboard shortcut.

In that same custom layout, you can also select to ignore hidden windows which will ignore apps and windows that weren’t 100% visible when you took the snapshot. You can even automate this when resolution changes on your MacBook, or when you’re hooking up another display.

The best part of this is that you can set this up this for several placements of different (or the same) windows so you can select between these in the popup menu, or make a shortcut for each of them.


In my opinion, Moom is almost magical. It’s a simple idea worked out so incredibly well, it makes me smile every time I use it. It also wins big when you compare it to other apps that are based on the same idea.

For €10.50 you can’t afford to miss out on its time-saving, nerve-sparing functionality. At the very least, you should give Moom a try. It’s free for the first 100 “Mooms”. Moom is available in the Mac App Store, but also on the developer’s website and as so often, the updates for the latter are  just a tad faster.
