Fedilab on Android supports Mastodon, Pleroma, Pixelfed, & Friendica, according to the Play Store description. Reviews are a mixed bag. I have not tried it myself. Reviews sound like it does a semi-decent job at some things but it's missing a lot of little QoL things that people seem to expect. Though, to be fair, the whole fediverse thing was only like six people until about a week ago, so I suppose it's to be expected that these kinds of apps are in their infancy.
@ilovededyoupiggy thanks I'll check it out! True, it's so exciting to think about how new this all is!
I don't know of anything, but I would definitely be interested to hear if anything is in the works
