Upscale is a tweak that will allow you to change the screen resolution of your iDevice. You can for example, implement the resolution of the iPhone 6+ or the iPhone 5s.
After you have installed a new section in settings where you can choose several different resolutions: that of the iPhone5/5s, that of the iPhone6/6Plus. You will also have the option to apply a custom resolution, but be careful no to put anything. Otherwise, you end up with an iOS which is unusable.
