I have been using the Thunder app. It's not bad. Definitely a hell of a lot better than the interface of using the desktop site on my browser. It low-key confuses me and I still struggle to navigate it but I'm just so used to reddit. I miss our snark as well but am glad we are here at least and I hope our regulars find their way over here
Jerboa is the official Lemmy mobile app, made by the platform's developers. It's pretty good, but like with Reddit mobile apps it's best to shop around. Other apps have different feature sets, different looks and feels and (whispers fewer bugs.)
