A crest icon on your home screen or dock that opens straight to the classroom — full-screen, with no browser bar, and it keeps the pages you've opened available even offline. No app store, nothing to download.
Safari
Apple offers this only in Safari, not Chrome, on iPhone and iPad.
Chrome
If you don't see a prompt, use the ⋮ menu and look for "Install app" or "Add to Home screen."
Chrome or Edge
Safari on Mac doesn't install web apps; use Chrome or Edge, or just bookmark the site.
The app is the same Lyceum Mundi site — installing simply gives it its own icon and full-screen window. You'll always sign in with your usual account.
