It is an easy to use, drag and drop for fill and submit forms. It seems to make it very, very easy to amend the built-in templates, deploy the form to your audience and then analysis the responses.
As far as I can see, it currently does not allows scripting. Since it is not pitched as an advanced development tool requiring programming skills, I doubt if it will ever have scripting ability. So things like calculations, dynamic changes are out. However for a "fill and submit" type form it certainly fills a gap.
