It would be interesting to see how your profits may differ if you were able to sell the apps on the Android Marketplace (without ads). I've been leery about trying ad-based monetization, but it looks like it is working fairly well for you.
I'm really embarrassed that I used the wrong number for the ROI. I fixed the article, but unfortunately I can't change the title of this link on Hacker-News. Hopefully I don't lead people astray making them think that MochiAds is a viable option for advertising their iPhone apps!
Has anyone had any success advertising their iPhone apps? I'm disappointed MochiAds didn't yield a higher ROI. It seems like their ads could be more effective, considering they are blasted at the user, in the center of the content they are looking at.
This is certainly an inspiration for developers that want to take the time to make a quality game, instead of trying to "game" the app-store with submissions like iFart, etc.
I agree...I want to see the algorithm for drawing rounded rectangles! I assume that he was able take his oval rendering code and use it for the corners of the square. Never mind, that would probably still leave the story unsatisfying.
