Totally worthless app. I would give it zero stars if possible. I have an account but the app just won't allow me to login. When trying to login it says no account with that email, when I try to register it again it says the email address is already registered. When trying to login using a one-time code, it's being sent to my email but when entering the code it says it can't find an account. I can login on my pc using my email, but the app just won't let me, no matter how I try to login.
