My app is http://www.cliniko.com http://www.cliniko.com I used the "likes" targeting in the facebook ads demographics to target occupations that my product is aimed at. I also targeted relevant english speaking countries. I have tried quite a few different styles of ads, but individual ads for each occupation that were specifically targeted has the best results. I guess I would advise creating many ads, and wording them specifically for each demographic you want to target. I also tried various pictures, but ultimately a screenshot of my app was the most successful. The majority of my users so far were acquired via the facebook advertising, it has been my most successful strategy.
