iPhone incompatible game is still broken

Was a great game when I could play it but every update makes it more incompatible with my iPhone 4s its gotten so bad I cant play at all. It takes 2 minutes to load then when my trainer comes into view it immediately crashes. I cant play at all anymore. Nantic screen shows up stays there for 2 minutes and then crashes. Does not work at all
