Easily manage your windows

SizeUp is the bigger brother to TwoUp.

SizeUp allows you to quickly position a window to fill exactly half the screen (splitscreen), a quarter of the screen (quadrant), full screen, or centered via the menu bar or configurable system-wide shortcuts (hotkeys). Similar to "tiled windows" functionality available on other operating systems.

Additional features include moving windows from one monitor to another, from one Space to another, and restoring a window to its original size and position (SnapBack).

This app is utterly fantastic. I have been missing a window manager like this on the Mac for years. Bought it straight away.

After more than half a year using this, I can still say that it's been put to great use every day and I've never experienced any flaw in SizeUp ever.

Personally, I never use the quarter-screen (Upper L/R and Lower L/R) views, but the Full Screen, Centered Window views as well as half-screen (Upper/Lower Horizontal and Left/Right Vertical) views are essential.

This app is great. I didn't try it for a while thinking I wouldn't use it, but now I hate sitting down at a Mac that doesn't have it.

Exactly the tool I was looking for. Does everything I need it to do. Especially multi-monitor + spaces support and the ability to customize the window split regions are great.

Conclusion: Great tool for a fair price

Very, very nice. Also bought.


I'm very impressed and so will you! Guaranteed satisfaction.

I can't stress enough how much I was looking for an app like this that could deal gracefully with windows management on OS X, and with multiple monitors support.
Used it, bought it. It's just awesome. Happy release!

Killer feature is instant monitor switching for an app. Essential for any dual monitor setup. Bought!

Tested for 5 minutes, and immediately bought! One of the things you ask yourself why they are not integrated in OSX.
