Rabbytte on your phone
Rabbytte installs straight from this page — no app store, no download file. It gets its own icon and opens full-screen like any app.
Burrow for Android — the browser
A real browser with Rabbytte as its engine. Download the APK, open it, and if Android asks, allow installs from this source — it lives outside the Play Store, so that one-time permission is normal.
Android & Chrome — instant install
Open rabbytte.com in Chrome, tap the ⋮ menu, and choose Install app (sometimes "Add to Home screen"). Chrome may also offer an Install button in the address bar — desktop Chrome and Edge included.
iPhone & iPad
Open rabbytte.com in Safari, tap the Share button, then Add to Home Screen.
Mac
The full Burrow browser — tabs, address bar, Rabbytte built in.
