Ask HN: iPhone apps that didn't make money?

Recently we have been hearing a lot about the iPhone apps that are making 10-20,000 $/day, apps that shot to the top of the App Store within weeks. It seems that all you need to do is to think of a clever/neat idea, hack it in couple of weeks and start making money.

I am sure this is not the case for every app. Just like in every field, the success stories make it to the headline, but the failures usually do not, so we only see one side of the coin

So I am looking for stories of iPhone apps that didnt make money, that didnt go any where. It would also give me (and others) a good insight if this indeed is as simple as it sounds.
