I just launched my app last week, I've been working on it for several months and I would love to get some feedback

My app is called SumMeUp and it analyzes a persons Facebook profile to find out a bunch of stuff like:

-Who forgot your birthday(and vice versa who did you forget?) -Who likes your posts the most? -Which is your most liked photo? -What do you talk about with your friends? -How good of a friend are you?

Long or short feedbacks, doesn't matter, any opinions are highly appreciated.
