I'm using Lemmy in a browser right now, are there any apps I can use for Lemmy on my phone and PC?

I have a GrapheneOS phone and Linux Mint on my personal computer.

Since noone else said it so far I want to kindly push back and ask why you would want to use an app in the first place. We have gotten too used to just download an app for every single thing and granting it all the permissions in the world. Sure the Lemmy apps are going to be open-source but still, I feel like we need to push the habit to just use a browser instead of an app more.
