Install

You'll need a running Suwayomi server. See Getting started.

Mobile

Android: download the universal APK below and open it to install. Smaller APKs for specific chip types are also attached.

iOS: the …-ios.ipa below is unsigned and has to be sideloaded. Add https://tsumiru.app/apps.json as a source in SideStore or AltStore to install it and get later releases as updates.

Which sideloading tool should I use?

SideStore signs and refreshes the app on the device itself, with no computer needed after setup. Best for most people.
AltStore expires every 7 days and only refreshes while a computer running AltServer is switched on and on the same Wi-Fi as your phone.
TrollStore installs permanently with no expiry, but only works on older iPhones and iOS versions with the required vulnerability.

With SideStore or AltStore the app is re-signed periodically, which those tools automate. There is no App Store build.

Desktop

Windows: download …-windows-x64.zip, extract it anywhere, and run tsumiru.exe.

macOS: download …-macos-x64.zip, extract it, and move the app to Applications. If macOS blocks the first launch, approve it under System Settings → Privacy & Security.

Linux: the Flatpak is recommended and auto-updates.

flatpak remote-add --if-not-exists tsumiru https://flatpak.tsumiru.app/index.flatpakrepo
flatpak install tsumiru app.tsumiru.Tsumiru

Existing Flatpak installs keep receiving updates under io.github.aaronbamblett.tsumiru; no data, settings or logins move. AppImage/deb also keep that ID.

For a portable option, download …-linux-x86_64.AppImage, mark it executable with chmod +x, and run it.
