I also like it. Too bad that leaving behind a comment on a post is not yet possible. But like you wrote the future looks bright, very bright for Appics.
At the moment I do consider it the Instagram of the Steem dapps. When posting one doesn't feel obliged to write a lot of text to comply to general (unwritten) steem rules.
The biggest problem they do have at the moment is the registration process, this should be their top priority at the moment. The app can be as brilliant but if people do need to perform a lot of action to register they will not use it.
