One really annoying thing is that I ran thru the whole story and added my habits... then wanted to save by creating a profile. Typed in my email address and preferred password.
And then it stopped working. Both the buttons didn't work, clicking on the greyed-out area didn't work either.
You had a great app there buddy, but just lost me and potentially many others.
