I landed here after RIF stopped working on my device and followed RIF link. This will be my new place to find content and see aggregation. Here it is to the end of reddit that starts today! 🍻
There are several. Unfortunately, they are all in early alpha. Lemmy wasn't quite ready for the mainstream, so the developers are scrambling a bit. That said, the improvements, even over just the last week or so, are impressive. Even if the apps are currently a bit threadbare and buggy still.
Jerboa is available on the app store. I'm personally using Thunder, though you need to download it from GitHub right now to use it. There are several more out there, but I've not played with them yet.
I think the apps will drastically improve in the next month so I'm just using a mobile browser until I see which one becomes the best. The mobile browser is already way better than reddit on a mobile browser so it's not bad.
Currently using Connect for lemmy which feels pretty close to RiF, though the Dev of Boost is making an app for android that looks just like RiF from the screenshots so that looks promising! The next couple of months will likely be a period of trial and error for a lot of folk. Exciting times.
