As an iPhone developer, I am always checking out the competition to see what the more successful applications are all about. I especially pay attention to reviews submitted by the users. What do they like about the game? What don’t they like? What suggestions do they have to make the application better?
This has nothing to do with copying someone else’s idea. It is driven by a healthy admiration and respect for the teams that created the apps, and it’s about trying to find out what the apps have that make them a hit. The reviews give me a direct view into the mind of the user. Traditionally, a company could spend millions of dollars on marketing research to get this information, but it’s available for free on the App Store!
