Library no longer waits behind background syncs

The Library screen could stay loading for minutes while the app's AniList sync waited its turn in the background. It now loads right away.

Kaeri 0.2.2

Windows fixes

The Windows app no longer crashes on its second launch, and the starting screen shows as soon as Play is pressed. Pages show placeholders while they load, Search sits in the sidebar as on the Mac, the Calendar draws like the Mac's, and Home fills wide windows. Dates, numbers and WinUI's own words follow the app's language, and trailer previews hide their controls again.

Train

• Version: 0.2.2 (patch), committed as "Release 0.2.2".
• Branch: train/2026-11-03 from main, with fix/windows-start-and-width merged (it carries fix/windows-skeletons, fix/windows-calendar and fix/windows-spoilers).
• Outside desktop/windows: kaeri-ffi and kaeri-mpv-host ask mpv for the swapchain off the app's UI thread (swapchain_of), plus i18n/en/platform-windows-browse.ftl.
• Checked: built and validated on a Windows PC. Mac-side local checks were skipped at the maintainer's call; CI covers the rest.
• All 35 commits are signed and verified.

Sync between devices, watch party chat and skip times found from the audio

Your devices can now share where you stopped, your history and your settings. Pair them on the same network, or sync through a cloud folder you already use. A recovery key lets a new device read the history back.

Watch together has a chat. Send a line or a reaction during the episode, or hide chat in Settings if you'd rather not see it.

Kaeri can find an episode's opening and ending from the audio, by comparing it with the episodes before it. You confirm or undo what it found, and the audio prints it compares stay on the device.

Episode lists show each episode's synopsis, in the title page and in the player's Episodes panel.

Browsing has a few extras: a period for Trending, Surprise me, dub counts on the cards, and Go to episode for long series.

The player's starting screen now says what it is doing while it finds the episode, and offers a way out when a start takes long.

On Android, opening a title from the results shown while typing a search no longer crashes.

Terminal

The installers are the .pkg on macOS, setup.exe on Windows and the .deb on Debian and
Ubuntu. Each one puts kaeri on your PATH and adds a launcher, so you can type it or click
it. The launcher opens your terminal, because Kaeri runs in one.

On any other Linux distribution, use the AppImage: chmod +x it and run it from a terminal.
Nothing is installed. Every Linux build needs glibc 2.28 or newer.

The .tar.gz and .zip archives hold only the binary, for putting on your PATH yourself.
Once it is installed, kaeri --update takes each new release.

These builds are not code-signed. macOS stops the .pkg the first time it opens: choose Done,
then Open Anyway in System Settings › Privacy & Security. Windows SmartScreen warns about the
installer: choose More info, then Run anyway.

mpv and ffmpeg are not bundled. Kaeri drives mpv for playback and runs ffmpeg to mux
subtitles into a finished download, so install both first; see the
requirements.

Check a download against its .sha256 before running it.

Every package carries the licences of what it is built from in a third-party folder, the Rust
crates' among them, and kaeri-0.3.0-rust-licences.txt has those for all four builds.

Kaeri doesn't host any shows. You add your own sources. See https://kaeri.app/legal/.

Apps

Kaeri for Android phones and TVs, the Mac, iPhone, iPad, Windows and Linux, on the same engine as the terminal app. Like
it, the apps host no content and supply no sources. You add the sources you are entitled to use.

Android

kaeri-0.3.0-android-arm64.apk, for Android 15 or later on a 64-bit ARM phone or tablet.

Open the APK on the device. Android asks once whether the app you opened it from, your browser or
file manager, may install apps: allow it, then choose Install. The APK is signed with Kaeri's
release key, so each release installs over the one before and keeps your data. It is not on
Google Play, and Play Protect may offer to scan it. Once it is installed, the app updates itself
when you choose Update in its notice or in Settings › About. The first time, Android asks you to
allow it for Kaeri too.

Android TV

kaeri-0.3.0-android-tv-arm64.apk or kaeri-0.3.0-android-tv-armv7.apk, for
Android TV and Google TV on Android 11 or later. Most TV boxes, including the Chromecast with
Google TV, run a 32-bit system and take the armv7 file; the Nvidia Shield and newer boxes take the
arm64 file. If the install says the app is not compatible, try the other file.

Install it with a sideloading app on the TV, or with adb install and the file's name
from a computer on the same network. It is signed with the same release key as the phone app and
installs beside it. It is not on Google Play. Pair it with your phone from the TV's first screen.

Mac

kaeri-0.3.0-macos.dmg, for macOS 26 or later on a Mac with Apple silicon.

Open the disk image and drag Kaeri to Applications. The app isn't signed with an Apple
developer account, and it is not notarized, so macOS stops it the first time it opens:

1. Open Kaeri, and choose Done when macOS says it cannot verify it.
2. In System Settings › Privacy & Security, under Security, choose Open Anyway beside the message
   about Kaeri, and confirm with your password or Touch ID.

That is once for each version you download. Right-click › Open no longer skips the check since
macOS 15. From a terminal, xattr -dr com.apple.quarantine /Applications/Kaeri.app does the
same. Once it is installed, the app updates itself when you choose Update in its notice or in
Settings › Integrations, and macOS does not ask again.

After an update macOS may ask again whether Kaeri can use what it keeps in your keychain.
Choose Always Allow.

iPhone and iPad

kaeri-0.3.0-ios-unsigned.ipa, for iOS or iPadOS 26 or later.

The .ipa is not signed for any device. Install it with AltStore or
SideStore, which sign it with your own Apple ID as they install it. Add
Kaeri's source to either, and they offer each new release:
https://github.com/bitknox/kaeri/releases/latest/download/sidestore.json. They
use two of your Apple ID's App IDs, one for the app and one for its widgets, and an App Group the
two share. With a free Apple ID that signature lasts 7 days: AltStore or SideStore has to refresh
the app within that time, or it will not open until they do. Your data stays either way.

Windows

kaeri-0.3.0-windows-x64-setup.exe, or kaeri-0.3.0-windows-arm64-setup.exe for
Windows on Arm, for Windows 10 version 2004 or later.

Run the installer. It installs for your account only, with no administrator prompt, adds Kaeri
to the Start menu and to Settings › Apps, where you can uninstall it, and lets the app open
kaeri:// links. The installer is not code-signed, so SmartScreen stops it the first time:
choose More info, then Run anyway. A new release installs over the one before and keeps your
library and settings.

Linux

kaeri-0.3.0-linux-x86_64.AppImage, or kaeri-0.3.0-linux-aarch64.AppImage on
64-bit ARM, for systems with glibc 2.41 or newer: Debian 13, Ubuntu 25.04, Fedora 42 and later. It
carries GTK 4, libadwaita and the player.

Make it executable with chmod +x kaeri-0.3.0-linux-x86_64.AppImage and open it. The first
run registers it for kaeri:// links. The app updates itself: it downloads each new version,
checks it, and puts it in place of the AppImage when you choose Restart to Update in its notice or
in Settings. AppImageUpdate, AppImageLauncher and Gear Lever can update it in place too, from the
release's .zsync file. Without FUSE, run it with --appimage-extract-and-run.

Checking a download

Each file has a .sha256 beside it. With both in one folder, run
shasum -a 256 -c kaeri-0.3.0-macos.dmg.sha256 (or sha256sum -c on Linux).
