Window Magnet will change the way you work with your Mac! Easily snap windows into various sizes and positions by simply dragging them to the edges and corners of the screen. Maximize them, place them side by side or deploy them into all four quarters of your screen in the blink of an eye.
BetterSnapTool allows you to easily manage your window positions and sizes by either dragging them to one of your screens corners or to the top, left or right side of your screen. This lets you easily maximize your windows or position them side by side. In addition, you can set keyboard shortcuts in order to move and resize your windows the way you want.
Cinch gives you simple, mouse-driven window management by defining the left, right, and top edges of your screen as 'hot zones'. Drag a window until the mouse cursor enters one of these zones then drop the window to have it cinch into place. Cinching to the left or right edges of the screen will resize the window to fill exactly half the screen, allowing you to easily compare two windows side-by-side (splitscreen). Cinching to the top edge of the screen will resize the window to fill the entire screen (fullscreen). Dragging a window away from its cinched position will restore the window to its original size.
