I’ll second Firefox as I quite like the web app version of Lemmy. You can even add it to your home screen as a PWA which will remove the address bar and any sign that you’re just in a web browser

That said, I’m using the Sync app cause after updating my phone (I’m using Graphene), the PWA wouldn’t keep me signed in for some reason. It’s perfectly usable without a subscription; every few posts there’s an ad, but they aren’t super annoying and they all look like adds and not normal posts which goes a long way. You can make a one-time purchase to remove ads instead of a monthly subscription which is also nice.
