Sorry - very basic question.

I loaded Sky Demon on my old Nexus last November. It worked fatastically here and in Florida. I've a feeling it was always accessible from my recent apps menu.

I haven't used it sinced then. And now I can't get to it. It doesn't appear on any menu I can find.

It's still there because I can see it on one of the settings screens. But I can't find anywhere that invites me to run it.

Anyone know how to use Android?
