Its missing one thing...
I really think you need to do a better job of describing (for example) what an adverb is and maybe give a few examples on how its used in a sentance.
Other then that I think its a wonderful way to keep your mind sharp. I would have givein you guys 5 stars. Do as I sudjest and youll get them. It is a great app though! Good job!
