I'm interested in a "Fog of World" equivalent for Android. I've found Umbra, but I don't think it has feature parity with Fog of World.
I know there is an app on the iphone called "fog of world" so i googled that and found this game

hopefully this is what you were talking about
(I'm on Android too, had just heard of the iOS app) After some more looking, Umbra seems to be similar for Android https://play.google.com/store/apps/details?id=org.unchiujar.umbra2
Haven't used it, and doesn't have a lot of installs/reviews, but it is what shows up when searching around the place for this kind of thing on Android
