Useless

This app is completely and utterly useless. As soon as you click on it, it asks you to sign in... But you have no option to sign up or create an account... You cant use it at all until you log in.. When I tried logging in,
(I tried using my email account and Apple account)
it said "Error. Username or password incorrect". So yeah, useless.. :/
