I installed it back in April and uninstalled it tree days later :) because it was just too slow (but they had this feedback already and might have fixed this by now).
I do like the layout of it and it was pretty easy to navigate as a user.
The publishing process was not as intuitive though and quite confusing. I don't remember the details but I made a few mistakes and I'm not sure if I ever ended up publishing or if I gave up :)
Persionally I would prefer if it were a webpage like steemit rather than a separate app.
