There's an iPhone game that you have to dodge the red and orange squares what is it?

I've seen people recommending this game as an app that you should have on your iPhone, you are navigating through a course that is filled with red, orange and (possibly) yellow squares, if you hit any of them you die and you have to just see how far you're able to get. I can't find the name of this game anywhere, I'm hoping someone can help me identify the name or know what game it is I'm referring to, I really would appreciate any help you're willing to give me to help me locate this game.
