Carla Kay White was one of these people. She had an idea for a "Gratitude Journal", where you keep track of the everyday things you're grateful for. It's a great concept, and it can keep your spirits up when a prescription antidepressant fails you. Carla was writing her gratitude into a paper journal when she realized that her iPhone was just the platform for this tool. One problem, though – Carla didn't have any iPhone programming skills.
What she did have was a good idea, a background in project management, and some minor funding to bring her concept to light on the iPhone. Inside Secrets to an iPhone App is a short (88 page) tome that not only tells the story of how she brought Gratitude Journal (click opens iTunes) to market, but how anyone with an idea for an iPhone app can do the same.
