If you're a user of Google's Android OS on a tablet or phone, you can install the Citrix Workspace there to access applications by following the procedure below.
After you grant permissions, the app will open, and you'll get to the initial setup screens. Click 'Got It' and 'Get Started', and then enter the server name 'luapps.lehigh.edu' and enter your Lehigh username and password. If that goes according to plan, you'll see the favorites screen shown in the next step.
When you first log in, you arrive at your 'Home' screen, which will be empty. Tap the 'Apps' icon to see the apps available to you. Each 'app' has a 'star' button next to it. Click that to add that app to your 'Home' screen as a 'Favorite'. Remember to pay close attention to the gestures available -- for example, a 'three-finger tap' may be needed to display the on-screen keyboard. A 'pinch' may be required to zoom in or out.
