As a fun project, I started developing an Android app for myself a few weeks ago, because I already missed Boost for Reddit, even though it's still usable. So I took Boost as an inspiration and started working. It's come quite far and I have decided to publish it on Google Play, in case others feel the same way. It's still lacking some features, most notably the ability to see when someone sent you a message or replied to your comments, as well as the ability to create posts, but for casual lurking it's already quite nice I think. It will hit Play Store in a fews days.
As the whole Lemmy and Fediverse ecosystem is mostly open source at least for me the usage of non open source reader apps is out of the question. It is about freedom so i would love to see this also as open source.
Fair point
