How to promote an iPhone app (productivity / goal-setting)
Press packages are a start but the press gets tons of those. There's no way of knowing, but you could be one of several developers that sent a press kit for a similar application. 

You should definitely have a website for the product to promote it in the way you feel is appropriate. 

Also, going to developer, mobile, and computer conferences and meeting with Apple, relevant press folks, and interested users is a good way to get attention, just be sure to have business cards and promo codes handy for when you meet people and want to show them your app.

There are many articles and books that cover this aspect of iPhone development including strategies on working with the App Store as well, most going beyond the scope of the Q&amp;A format of this site.
