Fortnite APK is simply a file format used to install the Fortnite game on Android devices. APK stands for “Android Package Kit.” It is the same type of file used by Android systems to install apps. Normally, when you download an app from the Play Store, your phone automatically installs it. But when you download an APK file, you install the app manually. This is why many people search for Fortnite APK when they cannot find the game on official stores.
