You should also be sure to check out !lemmyapps@lemmy.world, where you can find discussion and connect with devs.
There is a pinned post at the top that lists all of the active apps. iOS especially has a couple that have not received updates in a while, although they may be still useful.
On a larger screen, you might benefit from using a web app. There are several good ones with very active development.
Is that a lot?
