Tried it out on my iPhone 6, got a bit of feedback (maybe these points are already addressed in the newer Android version?):

• Interface is nice, but it needs to have a landscape mode, especially for typing replies to posts. I just can't type fast in portrait mode.
• Is there a way to view your feed? I couldn't figure out how to do it.
• Italic text doesn't render properly in posts.
• Would be awesome if you could implement a favorites / bookmarks feature. I often come across interesting posts and either don't have the time to read them completely, or want to re-read them again later for reference. It's painful trying to remember how to navigate back to those posts later on.
