Yeahhh... Out of all those I tried, that was by far my favorite. So much so that I didn't even remember how unintuitive the regular website was til I had to shoot someone a quick message, fumbled uselessly through my chats, and realized I really had to google how to find my inbox on a site I've used every day for four years.
Despite his stated disinterest, there's apparently been talk about the dev re-releasing it for Lemmy instead and I can't tell if there's truth to that or not. The app store listing seems like some unnecessary work for just a placeholder.
......but I don't use lemmy, so I'll just have to see what Artemis is about.
