Other than utilities (like Nova Launcher, Last Pass, and File Explorer), and reading apps (like Google Play Books, Kindle, Nook, Libby or Overdrive, and KOreader); I have only loaded Border Siege. It's on my Note(s) though. MY eyes aren't good enough to use it on my Nova Pro.

It's an Android game, there's no iOS version.
It's called Border Siege now.
Border Siege. I've always loved Risk. While the graphics are somewhat simple on this one, the configurability, maps, etc. make it a game that I have played longer than any other mobile game.
Lost Within. The art, gameplay, sound effects, story, etc. are all very well done. It keeps you on the edge of your seat, jumping at sounds, hesitant to walk around the next corner, etc.
World of Goo. Fun, intuitive, puzzle game with plenty of content. This is one that I have played through multiple times to the end. Many other games I never make it to the end, or if I do I am unlikely to re-play.
Sonic Racing All-Stars or Transformed. I enjoy cartoony, kart-racing games, especially if they can be played multiplayer, and these are the best I've found on Android.
"Border Siege" which is Risk with many different interesting maps.
