Downloads

Every build, every platform.

Pick the platform you will sit the exam on. The desktop apps update themselves after the first install; the phone apps come through the stores.

macOS

macOS 13 Ventura or later. Signed and notarized; drag to Applications.

The first macOS release is being published. Check back shortly.

Windows

coming soon

Windows 10 and 11, 64-bit. A signed per-user installer that needs no administrator, and an MSI for managed school machines. Everything the app needs is inside the installer, so it installs on a school network with no internet.

What to expect on Windows

Linux

coming soon

Debian and Ubuntu through an apt repository, Fedora through dnf, Arch through the AUR, an AppImage for everything else, and a Flatpak. Needs glibc 2.35 or newer and WebKitGTK 4.1 — Ubuntu 22.04, Debian 12, Fedora 43 or later.

Distributions, repositories and the Wayland note

iPhone, iPad and Android

in testing

iOS 18 and Android 10 or later. Both apps are in closed testing and reach the App Store and Google Play after review.

Web

Everything except the desktop exam room also works in a browser at your olympiad's site, and your Main Team account lives at auth.main-team.org.

All files

Checksums are SHA-256. The desktop packages also carry a minisign signature that the app verifies before it installs an update; the public key is on the verification section of each guide.
