Rabbit Hole works better as an app

No app store, no download, no account needed. It takes about ten seconds and gives you a proper icon, a full screen with no browser bars, and lessons that keep working when your signal doesn't.

Works in Chrome and Edge. Safari on Mac uses File → Add to Dock instead.

Look in the address barThere's a small install icon on the right — a monitor with a downward arrow.
Click InstallOr use the three-dot menu → Cast, save and share → Install page as app.
It opens in its own windowNo tabs, no address bar. It'll be in your applications list like anything else.

What you actually get

A real icon, and a full screen with no browser bars
Lessons you've already opened keep working offline
Your progress is stored more durably than in a browser tab
Still no trackers, no ad networks, no third-party cookies

It's the same site either way — installing doesn't create an account or send us anything new.
