Hariette is hard at work to create an alpha release that is stable enough to start rolling out. Follow https://kbin.social/m/ArtemisApp (!ArtemisApp@kbin.social for you Lemmy users) for more updates and announcements on the app.
Hariette is also available at kbin: @hariette, and Mastodon: @hariette.
