lock screen/homescreen app launcher?

So, need some help. Was watching a video review of either the S6 or Marshmallow a few weeks ago, can't remember which, and saw an app that allowed the user to gesture from the corner of the phone both from the lock screen and the homescreen to generate an app menu that consists of most used or favorite apps. Trying to figure out what app does that... anybody know?

i am using swipepad but it only works from the home screen. i do not know of any app that works like that from the lock screen
