Ranked in these QuestionsQuestion Ranking
Pro Simple & GUI based
While you can set keyboard shortcuts, Moom has a very easy to use GUI to get it going right away.
Pro Snaps to edges
In addition to using the grid or the overlay, Moom can move and zoom windows by dragging them to screen edges.
Pro Quick powerful keyboard shortcuts
Moom comes with many preset keyboard shortcuts already set plus the user can go into the graphical settings of the app and change any one of them to a different combination of keys.
Pro Zoom button for all apps
Moom adds an overlay zoom button to the corner of all apps which allows any app to go full screen or be placed to certain section of the screen such as the top, bottom or sides. This works even on apps that do not normally allow for full screen views.
Pro Multi-monitor support
Pro Save window position and size
Users can set per app window position and size which allows for a great way to set up a tiling window experience.
Con UI for settings can be confusing
The settings for the app are pretty jumbled and are hard to get a grip on, especially for first time users. While all the settings one would need are there, they are difficult to find or understand, which requires a good bit of just playing around with the settings in order to get a feel for them and what they offer.
