However, there is one missing feature which can be a deal-breaker for some users. Don’t be fooled by its price, as it goes head to head with our top pics. Spectacle is an open source window manager app for macOS, so it’s completely free. If you are looking for a high speed and accurate window manager, this will be your best bet. However, one thing which goes in its favour is that it is more affordable. The only reason it did not top our list is the absence of the ability to customize the size of the app window. An app window can be resized in the top, bottom, left or right halves or to a quarter of your screen size in either of the four corners. You can use both keyboard shortcuts and trackpad to resize your windows. Magnet is the most reliable and snappiest window manager app of all the apps I tried. This feature along with its snappy performance took BetterSnap Tool to the top of our list. This is a very handy feature to have as you can set the window size as per your preference. There is no restriction while designating the area and the size of the app window. Basically, users can predetermine the size of the app window and assign a designated area to which the window will be snapped.

One of the major features which are lacking in other apps on our list is setting up customized snap areas. The same configurations can also be achieved by hitting the user customizable hotkeys. Dragging it to the top will make an app go full-screen. To initiate split-screen mode, just the drag the app window to the sides of the display. You can drag an app window in either of the four corners to resize them in a quarter of the screen size. Firstly, you can use both trackpad and keyboard to interact with the app. Although it received a tough competition from our second and third place apps, there are certain features which gave BetterSnap Tool an edge over the others. After using more than 20 window manager apps on my Mac, I came back to BetterSnap Tool to use as my personal tool.
