Organize your apps with folders
Use folders to keep your apps organized and easy to find. Two tips to keep in mind when labeling folders: Don’t be vague, and keep the folder name short and simple. Try to keep similar items together, like "Movies," "Music," and "Reading." If your folder evolves over time, you can always rename it later, so don't be afraid to play around.
Android: If your Android phone is running on the 4.0 version of the operating system, also known as Ice Cream Sandwich, you can create a folder by selecting and holding the home screen. A new folder will appear. Now you can drag and drop apps to it. On the 4.4 OS, a.k.a. KitKat, just slide an app icon over another and drop it in the folder. After a new folder appears, you're prompted to name it. After naming it, just drag and drop icons into it. If you need to go back and rename a folder, just open it and touch its name.
iOS: As when you're deleting an app on iOS, select the app you want to move into a folder until it begins to jiggle on the screen and grays out. Then, still holding the app you’ve selected, slide it over another app and drop it in the gray box that's appeared around it. To rename a folder, just open it, click and hold your finger over the title, and select the X next to the folder name. Then you can start typing. Just don’t forget to keep it short, as a folder can only fit 10 characters on the screen after you collapse it.
Windows: Out of the box, Windows phones don't come with a way to create folders, though there are apps you can download, such as App Folder, to create them. And you can still get more organized by "pinning" apps to the Start screen. Pin an app, also known as a tile, by tapping and holding the tile you want to move until it pops into the foreground. Then you just drag the tile to where you want it, and select the Start button when it’s in the right place. To unpin a tile you don’t really use, simply tap and hold the tile you want to remove, and click Unpin.
You can also enlarge your tiles to make the important ones stand out or shrink them so that you can cluster them into groups. To resize a tile, click and hold it until the Resize arrow appears. Then tap on the arrow until the tile changes to the size you want. When you're done, select the Start button.
But before you pin, unpin, and resize things, keep in mind that you only want to pin the apps you use every day. These could include your email, a social-networking app, an exercise app for that other New Year’s resolution, and your favorite photo album of your loved ones.
