I have a pretty good idea for an app that I'd like to make and I'd like to apply. However after reading through the article it seems as if the deadline has already passed?? Would I be applying for Spring 2017? Also, any advice on what constitutes a strong application (in other words: I don't yet have a working product, can I still apply? )
