Yes. However you can install a PWA (progressive web app) via chrome and firefox (perhaps other browsers but those are the ones I use). The PWA allows you to use lemmy when logged into your instance of choice and it acts like a mobile app. To install, go yo your instance in a browser, then check our options. For chrome, it says add to home screen. I believe firefox it says install app. https://lemmy.world/pictrs/image/4ddba9db-456a-460d-9736-ff166e30c85d.png
