Amino is an app where you can join things called "aminos" and meet people of a similar interest, there are aminos for almost every subject you can think of. You can join chat rooms and you can make friends. You can post things like tasty fanfics, but not too tasty if you know what I mean ( ͡° ͜ʖ ͡°). You can post your art and you can even do polls on subjects. There are legit endless things to do. You just gotta keep it within the guidelines. Its really fun!
