Is there any app locking application available on wp 8.1

[Windows Central Question]

Is there any app locker available in wp store 8.1 so that i can lock individual apps rather than locking the whole phone. I have tried many apps but they all have the loop hole we can simply swipe left and can open any app f the main menu. Kids corner is also not that good, it security can be broken easilly. Guys pls help.
