Unity iOS Graphics are bad

I just got unity ios, and I made a new project, and I have a character with a gun, but the problem is that everything has horrible graphics. I have seen ios games look way better. how can I get the graphics to look better. I realize this isn't a lot of information, but I cant really give you guys anymore. It runs smoothly on my ipad and iphone, so what do you think is going on?

Did you use the mobile shaders?
