Using the websites as PWAs is perfect IMO. I'm using the Kiwi browser (any chromium-based Android browser should be able to do this, as well as Firefox etc.).
Go to whatever instance you're using (like lemmy.world or lemmy.one etc.), go to the drop-down for settings, and find "Install App" or "Add to Homescreen". This should install it as a PWA (there you can also choose if you want it on your home screen, in the app drawer, or both), so if you click the Lemmy icon on your home screen/app drawer, it should be a fully proper app now (no address bar, could in theory support notifications, offline usage, etc. depending on how the PWA was coded).
I also tried Jerboa, but using lemmy.world directly as a PWA has been a great experience.
