iphone 6: Making some apps not need passcode On my iPhone6, I have set a passcode to unlock. On a locked home screen, the screen can be slid up to run some apps (e.g. flashlight, timer/clock, calculator, camera, YouTube) in the locked state. Is it possible to add some other apps to run while it is locked? 

For instance, I want the phone to have a passcode to unlock, but want to let the Dictionary app to be run without requiring to enter the passcode.

Is that possible?
With the exception of the Clock, Camera, and Calculator apps (which can be opened in Action Center (if you have it enabled in the lock screen)), there is no way to open any app without a passcode.

There is limited functionality with push notifications (but only on certain conditions, like, say, a tweet pops up in the lock screen and you can either retweet or favourite the tweet) and in Notification Center (if enabled in the lock screen), but that depends on whether or not the app has support for either one.
