I'm a dirty Android user. But remember that Lemmy is ActivityPub.
If you have a Mastodon account (like the one I'm using right now to send you this!), you can follow Lemmy communities. I just put the link to the community in the Mastodon search bar and a "profile" showed up for me to follow. Then I followed it and posts from users show up in my Mastodon client.
It's not perfect - the Android Lemmy app actually does a better job, generally. But it's honestly a reasonable workflow and it makes my Mastodon feed more interesting too.
