I use it a lot, just a heads up for anyone interested, on google play the app is paid, but the app is free on F-droid and uploaded by the same devs, no features missing to my knowledge.
Think of the google play app more like a donation (or if you are like me, buy it because you are too lazy to got to F-droid) but be aware the app is actually free and one of the best when it comes to mastodon.
A feauture it has is that it lets you have as many timelines as you want, be it for instances or even tags so that you are not restricted to your subscribed, local and all but you can just choose a random instance and save their timeline to browse whenever you want.
Edit: forgot to mention, technically it supports the entire fediverse, but you will be restricted to your mastodon UI if you follow lemmy or kbin accounts, which means you will see likes and boosts instead of upvote/downvote. It is not ideal, in fact I would recommend having a separate lemmy app, but you can do it.
