To start, you can either login with your Twitter credentials or continue without signing in. Certain features are only available if you sign in.

To create or view a Twyn, you can select a Twitter ID from the Featured, Most Liked and Most Viewed lists. You can also enter a Twitter ID via Search.

You can also see how similar Twyns are via the Compare feature. You can select Compare from the left hand menu, or select the Compare icon at the bottom of a Twyn page. You can also add a Twyn using the Quick Search.

After you have viewed a Twyn or Comparison, you can share your discovery with your friends via email, SMS, Twitter, Facebook and many other social media sites.
