If I'm ever setting up a new version of macOS, this is one of the first things I install. I've been using this app since Yosemite when macOS did not have window splitting in the operating system (this came along in El Capitan). Now I'm on Mojave but I've kept using this app over the built-in macOS window resizing functionality because it more closely mirrors the windows resizing in Windows and Linux (common distros like Ubuntu). One of the key distinctions here is that you can make it resize in your current desktop with key shortcuts. The built in OS window splitting implies that if you want to move a window to a side, you have to pair it in half with another window (meaning you have to know which window you want to split half the desktop with) or you have to have it full screen.

My favorite parts about the app are the ability to assign keyboard shortcuts to moving the windows and it runs with a subtle and clean icon in the top bar making it almost feel built in with OS.

Love the app - use every single day

I love this app. I can effortlessly have email opened on the left side of the monitor and any other app on the right. Fits perfectly on the screen every time. I use an LG thunderbolt display, so a lot of screen real estate is available. This app makes use of all that space. Tried an alternative program (can’t remember the name) which gave more options, but that software was not capability with some of the other software, so i had to uninstall.

My only recommendation is for the programmers to make this app go completely in the background. The frustrating thing is realizing that you have accidentally QUIT the program, so all your keystrokes do different things which gives odd effects that you aren’t expecting until you try and remember the name of the app and re-open. I have this already as a default startup option, but would like the app hidden (not just put in background), so I can’t easily quit it.

Really like this app. Makes me love my mac even more.

P.S. FOR THE USERS WHO DON’T WANT TO BUY THIS APP, there is a built in OSX feature that does almost the same thing. Just press and hold the green dot on any window, and it will automatically split the screen. However, I don’t use that, since it takes the computer into full screen mode which I don’t use most of the time. So, while they do similar things, the OSX feature is not a substitute for this app exactly.

Pretty perfect for my needs

Sometimes I watch youtube/netflix/hulu and use a browser at the same time. Sometimes I use onenote and a browser at the same time. Sometimes I use sublimetext and reference github at the same time. Sometimes I clean data w/ textwrangler and upload data using filezilla or the terminal window at the same time. Etc. etc. This app lets me do all that quickly and efficiently.

I’ve been using the splitscreen app almost since it was released, and have yet to find a better solution to using and manipulating two screens/apps at the same time. I introduced it to my colleagues a few years ago and we’ve all been using it since.

addendum: I do mostly back-end work, so usually only need one monitor.
