You can access the app independently, but we recommend you use either for a better app experience. For example, when you choose to login, we use your Facebook likes to customize your teams and leagues on the app.  In addition, if you forego logging in via Facebook or G+, you may be required to log into to either social network later.  Using Facebook or G+ to login from the start can save you both time and any hassle.   Keep in mind: We will never share your personal information without first receiving your consent.
