The Cydia Tweak NCPop has been officially released and works with devices that have iOS 9 or higher. NCPop is a new jailbreak tweak that adds a 3D animation to apps when launching Notification Center. As you open it, the app behind it will start to shrink in size. The other important thing you should note is that NCPop only works for apps in the Notification Center. So it does not work when you launch Notification Center from the Home screen or lock screen.
The tweak comes with a couple of customization options that can be accessed via its preferences pane in Settings. You can enable or disable it on demand, adjust the amount by which the app shrinks, configure the sensitivity level and define the fade percentage.
If you’re in to give this tweak a try, NCPop jailbreak tweak is available for free from BigBoss repo. Simply install the tweak on your device and configure it the way you want to use it from the preference pane which you can access from Settings app and then you are ready to make the best use of it. To install this program requires a jailbroken device (see if and how you can do the jailbreak to your iPhone by clicking here) and you need an Internet connection to download the package.
