I'm particularly curious because I recently started a mobile contracting company for iPhone and Android applications, as well as websites. We've only been doing fixed price contracts so far, but we've been wanting to try our hand at writing our own applications too. We're just about done with our first three applications (in the process of getting one into the App Store, and two more are ETA to be done by the end of the week).

In case you're wondering what normal costs are for mobile application contracting: For simple apps, a fixed price would be in the $500 to $2000 range; something moderately complicated - say, an interface to a social network - would be in the $4000-6000 range; after that it usually goes on a case by case basis depending on what the customer wants.

(By the way, completely shameless plug: we're going to be done with our currently running contracts soon... so if anyone happens to be interested, contact info is in my profile. We build websites, Android, iPhone, and iPad apps, mostly.)
