I have a GrapheneOS phone and Linux Mint on my personal computer.
There are a bunch. I tried Jerboa and then Voyager on android. Jerboa is the official one, I found Voyager to be a bit nicer, but in the end I find it better to use a browser including on my phone. I sometimes think of writing my own client to reorganize the UI to be more like a usenet client, or maybe even just write a Lemmy to NNTP gateway. I don’t understand why it wasn’t done that way in the first place.
My personal pick is Thunder. Probably has less bells and whistles than some other choices, but it still has everything I need and then some. Looks pretty nice as well and follows the revised Material aesthetic so it should fit in nicely with the rest of the Graphene UI.
And as a cherry on top it’s both libre and gratis!
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.
I have actually decided to set it up as a browser on my phone since I tried everything and didn’t really like them, and I’ve set it up as a web app on my PC.
I would advise against using Voyager since it tries to track link shares by first directing you to their website first. It made me uncomfortable so I switched to Summit. I had tried interstellar but wasn’t a fan of the layout or how they didn’t have the ability to handle going into cross-posted links on android at least. Also, had to use obtainium to install it. Summit on F-Droid supports the full fediverse. I had tried a fourth but can’t remember its name, I dropped it because it lacked support for piefeed.
What do the apps give you that Lemmy’s default UI doesn’t?
I enjoy Voyager for mobile.
I use Summit. I used to use Sync, but I think it’s been abandoned. At least that was the sentiment when I last used it about a year and a half ago.
You can also try boost.
I recommend this site to compare all the apps across various platforms
I think Interstellar and Voyager are available on both android and Linux
Personally I would suggest picking different apps on each, since it’s all the same backend data. A mobile focused app may not behave as nicely on desktop.
You can likely also run some of the alternative UIs as PWAs or full apps, but I haven’t explored that yet
In this thread: everyone suggesting a phone app and not answering the question.
Two different ones would also work
Ah I totally missed that detail in the original question! Is there an app that does both desktop and mobile?
You can technically use Voyager on desktop and mobile. You can access the web client here: https://vger.app/
You might as well just continue using whatever web browser and access your home instance directly at that rate.
It’s also a standalone app as a flatpak, if that makes a difference: https://flathub.org/en/apps/app.vger.voyager
Oh hey! That’s cool to know!
I think that’s the question OP is asking too. You could do some convoluted shit to get an emulator running and just use whatever phone app on both I guess.
