I forgot my password AND email for twitter..I'm only logged on in the app.?

Well If you don't know your email or password then there isn't anything you can do. Sites like twitter or Facebook try to avoid accounts being hacked so without those two critical log-in items, you cant get into the account. (Unless you have a mobile number attached to the account, but if you have a twitter app then I don't see why you would)
Advice, Don't ever log out of twitter from your phone, or don't delete that twitter app. If you do then you will permanently lose access to the account. Hope this helped :/
