Canonical has laid out its plans to release Ubuntu phones at some point in 2014 -- but you don't have to wait that long to get a little bit of Ubuntu flair on your current Android device. Unity Launcher brings Ubuntu's interesting swipe-in sliding app selector to your device without changing your current launcher setup.
When you first open up the settings of Unity Launcher, you need to set the sizing and position of the swipe area before you can use it. You have to edit the "edge width", which essentially tells the app how much of the screen to have "reserved" to recognize when you're swiping. As the app indicates, the smaller the area the better because it will make that portion of the screen unresponsive to normal UI touches. I made the area on my Nexus 4 almost as small as the slider goes without any ill effect on the functionality of Unity Launcher or other apps I was using. It does take some getting used to once you make the area so small, but it quickly becomes a natural gesture.
Beyond the width of the swipe recognition area, you can also change how high the area is, it's color, sensitivity and position on screen - left, right, top bottom and everywhere in between. Once you've got it set up and working as you'd like, you can edit how long to have the tray visible when you swipe it in (default 1200 worked fine for me), the animation delay and the background styles of both the tray and individual app icons themselves.
There's a free version of the app with very limited functionality, but luckily the paid version is only $1.99 to unlock all of the bells and whistles. If you're interested in trying out a little slice of the Ubuntu phone OS on your current device, it's certainly worth a try. Download here.
