Once install the tweak on your iPhone, go to the tweak’s settings panel and you can choose what apps you want to appear in the notification center so that you can quickly launch them… The tweak adds a fourth tab alongside Today, All and Missed in Notification Center for opening apps directly from the notifications pulldown. An unlimited number of apps can be added to Apptray, configurable from the tweak’s dedicated menu in the Settings app…
Apptray has a few other interesting options, including a slider for adjusting icon opacity and a toggle switch for enabling or disabling the tweak entirely. In order to ensure the security of iOS devices, the tweak cannot open apps from the Lock screen when a passcode is set. In that instance, tapping on an app icon will simply do nothing.
