This is probably the first HN readers have heard about your app, and it doesn't appear to be backed by a larget company, so they probably just skimmed the link in the new list and didn't even click on it. One suggestion would have been to title it "Show HN: My first iOS app, real life scavenger hunts, covered in Geekwire", so at least it would make this ask section, where the links get a little bit more of a chance for upvotes. Neither of your submissions had any upvotes, so I'm guessing it just got pushed off by a rush of other news. In particular, for the last few weeks here, the front page has been overwhelmed with one story in particular, so startup launches and programming topics are going to fall by the wayside - it may have just been a bad time to launch on HN.
