He isn't the youngest kid to write an iPhone app, but 11-year old Cameron is wise beyond his years. He is donating a substantial part of the proceeds from his drawing app iSketch to the Mattel Children's Hospital UCLA.
Writing to Crunchgear, Cameron's father explains the situation:
My son Cameron is 11 years old and, last year, he had a medical problem that prevented him from participating in the physical activities he otherwise enjoys. (He is nearly fully recovered.) During that time, Cameron became interested in computers, and he began to read anything he could get his hands on. He watched Stanford University professors on iTunes, scoured the web for articles on programming and taught himself several different programming languages. (Neither my wife nor I have any idea how to program.) Cameron began to focus on the iPhone and iPod touch devices as the "apps" offered for sale for use on those devices seemed really cool to him. He began to work on a few different apps. After completing some summer camps on programming and continuing to read and learn, Cameron finalized an app, which he calls iSketch, and submit it to Apple. The app, which is a painting/drawing program, was approved by Apple for sale on its App Store in December. (He has since updated it several times..)
Inspired by the care he received at Santa Monica-UCLA Medical Center and Orthopaedic Hospital, Cameron has dedicated a substantial portion of the proceeds from his sales to purchase entertainment and electronic items for Mattel Children's Hospital UCLA's Child Life/Child Development programs in Westwood and Santa Monica so that pre-teens and teens will have additional age-appropriate options available to them during their Hospital stays. Cameron's sales so far have been good, but he hopes to accelerate them so that he can donate even more to the Hospital.
Damn, that is humbling.
Despite Cameron's age, iSketch looks like one of the better drawing apps in the App Store. Even if you aren't interested in drawing on your phone, the 99 cent price tag is going to be worth every penny. [iTunes and iSketch via Crunchgear]
