I already did a hot or not app (with a twist) that got my whole town going including law enforcement and Apple took it down 7 days later. Nothing serious happened but they just were not happy. So now that that's gone, I might make something else after this semester is over when I need a break from coding SAAS. I was thinking about a trivia app perhaps. It doesn't have to be an exceptional idea because people are naturally passionate about the small demographic they come from and word travels quick. I want something simple that doesn't require too much code. What successful apps have you guys made for your high schools, colleges or small towns?
