Which one is for you
Pick Moom if
- Fits if you rearrange the same windows every time you dock your laptop
- Works for households with a few Macs, since one $15 license covers them all
Look elsewhere if
- Skip it if you're on Windows or Linux, or a Mac older than macOS 10.13 High Sierra
- Not for you if you want every future update included, since later ones may be paid after the first year
- Tight if you buy everything through the Mac App Store, which only carries the older Moom Classic at $6.99
- Watch out: the site doesn't say how long the free trial lasts
- Not for you if you automate with Shortcuts, as there's no direct support, only AppleScript for some features
Pick SizeUp if
- Fits if you'd rather resize windows from the keyboard on a Mac
- Works for people with several monitors and Spaces
Look elsewhere if
- Not for you if you're not on a Mac, as no other system is listed
- Watch out: the page doesn't name any macOS release newer than Sonoma
- Skip it if you want drag-to-snap layouts, because it's keyboard-led
- Watch out: the free trial has no stated end, so the page doesn't say what it limits
How we grade them
| 2.2GPAMoomFair | 2.4GPASizeUpFair | |
|---|---|---|
| Value for money | A$15 once and the licence is valid forever, covering every Mac you use plus the family in your household, with at least 1 year of updates. Utilities here sit at $2.99 a month in the middle, so that's five months' money and then done. | B$12.99 per license, below the $16 middle of one-time prices in this category, with a 60-day money-back guarantee. |
| Free plan and trial | CNo free version. There's a trial download on the site with no card asked for, but its length isn't stated, so we can't tell you how long you get before the $15. | BAn unlimited free trial, per the product page, though it's a trial and not a free plan. |
| Features | CWindow placing is its one job: a palette on the green button with up to 61 actions, snap zones, saved layouts, chained actions and full keyboard control. It's still that one job, and the FAQ says there's no direct Shortcuts support, only AppleScript. | BHalves, quarters, multi-monitor and Spaces, SnapBack, margins, AppleScript and global shortcuts. Nothing in the listing shows a gap in the core job. |
| Ease of use | CNo store rating on record, and much of it is something you build: layouts to save, palettes to fill, chains and folders to arrange. Hovering the green button for the palette needs no setup, but expect an evening of setting up before the rest is useful. | CNo store rating on record. It's driven by shortcuts you have to learn. |
| Platforms and integrations | DMac only. Moom 4.6 needs macOS 10.13 High Sierra or newer. There's no direct Shortcuts support either: the FAQ says some features can be reached through AppleScript. | DMac only, from Mac OS X 10.6 through macOS 14 Sonoma. |
| Best for | saving and restoring whole window layouts on a Mac | keyboard shortcuts for window sizes |

Key features
Moom
- Pop-up palette
- Hovering over a window's green button shows a palette of move and zoom actions. It can be customized with up to 61 actions, including folders, layouts and grids.
- Saved layouts
- Save the positions of a set of app windows and restore them later, for example when a laptop connects to an external display. Any-window layouts apply to the most recently used windows instead.
- Snap and drop zones
- Drag a window to a snap zone to move and zoom it. A saved layout placed in a snap zone turns its window positions into drop targets.
- Custom actions and chains
- Custom actions can be chained to run as one combined step or as a loop that advances each time it is used, and organized into nested folders.
- Hover
- Hold a set of modifier keys and move the mouse to move or resize the window under the pointer, even one in the background, without clicking.
- Keyboard control
- With the keyboard features enabled, windows can be moved, resized, centered and placed on an on-screen grid without the mouse, and custom actions run from a hot key.
SizeUp
- Split and quarter actions
- Fill the left, right, top or bottom half, or a quarter, of the screen with the frontmost window.
- Multi-monitor and Spaces
- Move a window to another monitor, optionally resizing it, or to another Space.
- SnapBack
- Restores a window to the size and position it had before SizeUp changed it.
- Margins
- Reserve space at screen edges or add gaps between windows.
- AppleScript
- Build custom actions such as thirds or anchoring a window to an edge.
- Global shortcuts
- Trigger every action from configurable keyboard shortcuts in any app.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
