The purpose of this tool is well described inside its title. APK Installer is a straightforward application that allows you to install APK files on your Android smartphone or tablet. It has the capability of finding all the APK files stored on your device and you can see a list of detected applications inside the user interface. And since we are on this topic, the UI rocks a minimal layout and there's not much to say regarding its design.
With the help of the integrated search function you have the ability to find specific APK files. Each found APK comes with additional information such as file name, version, size, logo and installation status. You are allowed to select multiple items and remove or install them on your device. This list containing your APK files can be sorted by name or size.
Another task handled by this simple tool is to show how much free storage space your device has.
