Does anyone have a list of either iOS or Android based apps for RPG Character Sheets?

Looking for an app or apps that can support D&D 5e, Numenera, Firefly, Call of Cthulhu, Shadowrun, to name a few. I found one that looks ok (Sheet Yourself - iOS) but not sure how good it really is as there are zero reviews on it. Also, would like the apps to be pretty much "plug-and-play", similar to the "Fifth Edition Character Sheet" by Walter Kammerer (for iOS and Android). 

Any suggestions would be greatly appreciated.
