For those that don't know: Hawaiian Words is a 1600 word translation dictionary. It has ads that can be removed via an in-app purchase, music and customizable backgrounds, and purchasable text-to-speech for the Hawaiian words. It also has word of the day.<p>It might not be for me or for you, but if people are buying it, I assume there's a niche market for this kind of thing.
I'm the developer of this app. The critique was really useful; I'm already starting to implement some of the suggestions.<p>Feel free to ask me any questions. I have a lot of data on which marketing techniques have paid off and which haven't. I just started running an online and print ad campaign in Hawaii Magazine.
