I must say that this article kind of turns me off to iPhone development. They made a <i>huge</i> marketing push for that app. Somehow they got press coverage all over the web. They ran a laptop giveaway for people who retweeted the launch. Their website and blog had great marketing materials. It seemed like everyone clued into the web heard about Convert the day it came out. This all resulted in a big spike that quickly died off after earning them about $100k. Now that the app is about to drop off the Top 100 list and they're going to raise the price, I imagine that sales will plummet even further.<p>People in the comments mostly say things like "to be honest I don’t use it that much" and "I originally purchased convert to support great app design".<p>It really paints a picture of the App Store being about gimmicks or quick hits that grab a bunch of attention long enough to rake in some cash before they fade into the past and out of our collective memory.<p>I'd like to build something more lasting. I'd like my sales curve to look just like theirs, except flipped around the Y axis.
