Is there a way to either add a calculator to the lock screen or to the quick setting panel? My work phone is a iPhone 6 and personally, (i.e. my opinion), is that I can swipe up from the bottom to access various apps like calculator, flashlight, alarm, etc... I know on my Note 5 I can already access the flashlight by swiping down from the top to open the quick settings panel. And I know that there is already a shortcut on the lock screen for the camera; however I can't find anything even related on the inter webs about adding the calculator. On my older S4 and Note 3 you could add widgets to the lock screen and calculator was one of them. Thanks in advance for the assist.
