#### Learn with flashcards, studied offline and synced between your devices

Halkyon is a spaced-repetition app for your own material: studysets of
flashcards, notes, learning paths and PDFs, reviewed on an FSRS schedule. Every
studyset is made by its learners: build yours for any subject, or copy one that
someone published. It works offline and syncs between your devices.

Learn from what you watch: play films and shows from your Jellyfin server,
and every subtitle line is split into dictionary words, with readings above
and the translation below. Tap a word, and it is a flashcard.

Dictionaries for Japanese, Chinese, Korean, German, Greek and English; kanji,
hanzi and Hangul written by hand, each stroke checked; exam plans for the
JLPT, HSK and Korean levels, with a daily pace to your exam's date; and
studysets published to Explore and copied, later releases coming in as
merges that keep your own edits.

You sign in with SimpleLogin, by Proton, or with an email address, a
password and an authenticator app. It connects to halkyon.li, the project's
instance, or to any other: everything an instance needs is in the repository,
to run your own. The app is AGPL-3.0 and the server SSPL-1.0, so all of its
code is public.

## Enable snaps on openSUSE and install Halkyon

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.

Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions.

### Enable snapd

Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.

You need first add the *snappy* repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.

Tumbleweed:

```
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
```

Leap 15.x:

```
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
```

If needed, Swap out `openSUSE_Leap_15.` for, `openSUSE_Leap_16.0` if you’re using a different version of openSUSE.

With the repository added, import its GPG key:

```
sudo zypper --gpg-auto-import-keys refresh
```

Finally, upgrade the package cache to include the new *snappy* repository:

```
sudo zypper dup --from snappy
```

Snap can now be installed with the following:

```
sudo zypper install snapd
```

You then need to either reboot, logout/login or `source /etc/profile` to have /snap/bin added to PATH.
Additionally, enable and start both the *snapd* and the *snapd.apparmor* services with the following commands:

```
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
```
