For mobile phone client applications for Lemmy, I generally prefer using Boost for Lemmy and Summit for Lemmy.
The Boost app is proprietary, as it offers an ad-free version available for a small fee. The Boost Lemmy client app features a Material You color theme that aligns closely with Material Design guidelines. Additionally, I find the rocket icon particularly appealing.
I particularly appreciate the Summit app because it makes it convenient to capture screenshots or photos of posts directly within the app, without needing to rely on the phone’s built-in screenshot functionality.
None actually, it’s good enough on the browser I think. Which is definitely not something I can say about Reddit these days. (I still use it through a browser, and without an account, but it’s a major PITA.)
