How can I make my GIF messaging app better?

Hey there everyone! About a year ago I had an idea for a GIF messaging app called Glyphic (it's on the iTunes store at the moment).

We did a soft launch at school in semi beta (basically just core functionalities) and had a great response.

Currently we're adding new features like posting on fb/twitter, sharing convos, group convos, usernames/easier to find friends (UI/UX changes).

I figured I'd reach out to HN to see what everyone thought we could improve on!

Much love
