With Screens running on your iOS device, follow these steps:
Tap the Settings (gear) icon.
Select Screens Connect.
Enter your Screens ID and password.
Tap the Next button.
Upon signing in, you should see every Mac or Windows PC you've installed Screens Connect on.
The next time you connect to this computer, Screens will determine whether your computer is available on your local network. If it's not, Screens will query our Screens Connect server for the computer's network information. This process is all seamless, and you shouldn't see a difference between connecting via local network and connecting via the Internet!
