Want some inspiration on how to build a business out of an app idea? Check out this great interview with the creator of GoodNotes. I love the way Steven grew the app and ended up building a team to take it to the next level. GoodNotes is a superb app and you can learn tons from this interview. Definitely, a must read.
Steven estimates he dedicated a solid six hours of coding every day when he was first developing the app, not knowing where it would go and whether it would be well received.
