Tusky

https://tusky.app/

Tusky is a multi-account Android app for Mastodon. It also supports Mastodon forks and Pixelfed, though with Pixelfed it still has some bugs.

It supports all Mastodon features, like photos, videos, lists, custom emojis, ... and it's still quite simple. It looks a lot like the Mastodon looks in the web browser.

Fedilab

https://fedilab.app/

Fedilab is a multi-account Android app for Mastodon, Mastodon forks, Pleroma, Pixelfed, PeerTube, GNU Social & Friendica.

It has more features than Tusky, but is also a bit less tidy.
