I search for 'Balls' and got many hits, most irrelevant and uninteresting.
Then I searched for the exact title of your app and got about 13k hits. None of the first 100 which was your app. I downloaded it through iTunes eventually.
That makes me wonder: how do you promote (iOS) app discovery? There are plenty of analytics startups for this, but is anyone trying to improve this process?
edit: Searched around for curated app websites / stores. There are some, but lack in depth and quality. I'm starting my own.
