There's this near little app called Handy. It's a drawing reference tool for hands and heads. You turn them at any angle and move the lighting around. I don't think it's free though.
I like the 8tracks app. Users create music playlists for pretty much anything you can think of. Anime, video games, sleep, ghibli, lots of different tags to explore.
For a game, I recommend Ridiculous Fishing. It isn't free, but it's a pretty fun game.
I've been playing To The Moon (not a iOS game). It's a pretty incredible, little game. I bought it during Steam's summer sale.
Been playing Lightning Returns too. It's not great. xp I just wanna see how this series ends.
