OK so you built a small utility app in a crowded space- see:

You released on May 18th only in the Mac app store with no other marketing and decided to withdraw on August 7th, i.e. less than 3 months later. What were you honestly expecting to happen? Did you really think that there was some pent-up unmet demand for your app? What compelling advantage(s) did it offer? Who did you think would be looking for it and how did you think they might evaluate options?
