~~wefwef~~ Voyager is a neat mobile-focused client I found that is similar to the Apollo client for Reddit. It is a web app (and probably the best web app I have ever used), so it takes almost no space to install and works on many platforms (currently the interface is styled to look like an iOS native app, but they are planning on making an Android theme).

Recently, they also released mobile apps, which work better than the PWA sometimes.
