Annabelle, if this was your idea, how did you execute it? Did you write / design anything? Outsource the app? Who are your partners?
It looks like FIPLAB produced the app (http://www.fiplab.com/). The website describes the product as "Need advice on how to reach out to that amazing new girl you can't stop thinking about, or taking things further with that girl you've always had a crush on? We hear you, and that's why we've created 'Dating: Ask a Girl'."
No mention of any Annabelle the character and co-founder, which is a pretty significant piece of the marketing puzzle.
So what I'm guessing is the geniuses at FIPLAB built and spec'd out the app, and got an attractive girl to join their project after the fact (or some variation of this). I'm not saying this to be a dick, your marketing tactics are great, if you carry it through it should pickup some decent press coverage. But come on, this is HN here, you weren't going to get off that easy :D
