Every now and then I type "skateboarding" into the app store and trawl through the pages of "xtreme downhill stickman sk8r" games in search for something new.
Found this yesterday and it's really good:
https://itunes.apple.com/gb/app/skate-champ-finger-skateboard/id719200961?mt=8It's online games of skate - top down finger flicking like True Skate and Touch Grind. What's really clever about it is that you learn tricks. So the more you practice a trick the more likely you are to land it. Also the controls make the difficulty pretty real - e.g a kickflip is easy, 360 flip much harder and a bigger risk in a game of skate.
