tl;dr: They spent $14,800 on two weeks worth of advertising and got 8507 clicks, some feedback and a few connections with people they didn't have the creative juice to figure out a way to connect with. The app is 'free for the holidays', so one can't relate that to CPA.

It is a very pretty looking polished app. I'm not sure I'd spend money to buy it myself, but maybe others would. I suspect it will take a long time to make back the $15k in advertising.
