Android phones

Pets OS becomes your phone’s Home Screen. It runs on top of Android and doesn’t erase it, so your calls and apps keep working.

Tap Download on your Android phone.
Open the file. If Android says installs from your browser are blocked, allow it, then tap Install.
Open Pets OS, follow the setup, and choose it as your Home app.

Version 1.3.0 · 4.7 MB · Android 8 or later

iPhone

Pets OS opens from its own icon, full screen, and works offline. Apple doesn’t let any app replace the iPhone’s own Home Screen.

Version 1.3.0 · updates itself

Computers · preview

The full Pets OS for computers, as a preview. Pick the download for your computer. It doesn’t replace your computer’s system.

Open the Pets OS download page and pick your computer.
On a Mac with Apple silicon, open “Start Pets OS” and it starts in its own window.
On Linux, Windows or Mac, the easiest way to try it is the PC virtual machine disk in QEMU. A USB image for Intel or AMD PCs is there too, but it hasn’t been tested on a real PC yet.

Version 11.2 · preview · Mac (Apple silicon), virtual machines and PC (Intel or AMD)
