Please also try to support #Friendica when you can, its a really underrated project and currently lacks a good mobile client that supports all of its features. Fedilab is the only app I could find on #fdroid that said in its description that it supports friendica, so this is my last hope of having a good friendica client on mobile.....
You can make long posts, as long as you want
Ability to format the text (bold, italic, underline).
Supports Markdown so you have full access to that.
You can add inline media.
With the above you can create proper blog posts.
