I am using the Memmy beta from TestFlight (IOS). It is inspired by the Reddit app Apollo.

I tried pretty much every Mastodon app on iOS at the time I moved over from the Birdsite to Mastdodon, and I settled on Toot! I like the UI and it does everything I need. I still use the web portal sometimes if I happen to be on my laptop.

Megalodon for android

Ice Cubes. It lets me follow other server's local feeds. Really handy.

Moshidon which is like Megaldon

I use Trunks, it's really great in terms of UI/UX.

I've been a happy user of Tusky (Android). I have my edit button, and I can jump between multiple profiles. So I'm a happy camper.

Ivory. Using it across iOS, macOS and iPadOS. As a former Tweetbot subscriber I love the interface and design.
