1. Have An Idea – A Good Idea

How do you know if your idea is a good one? The first step is to even care if your idea is solid; and the second step is to answer the question does it have at least one of the indicators of success?



Does your app solve a unique problem? Before the light bulb was invented, somebody had to shout out “Man, reading by candlelight sucks!” Figure out what sucks, and how your app can make the life of its user more comfortable.
Does the app serve a specific niche? Though there aren’t any stats on the App Store search, the usage of applications is certainly growing with the explosion of App Store inventory. Find a niche with ardent fans (pet lovers, for example) and create an app that caters to a specific audience.
Does it make people laugh? This is a no-brainer. If you can come up with something funny, you are definitely on the right track and your idea may be the golden one. Heck, I hit a red “do not press” button for 5 minutes yesterday.
Are you building a better wheel? Are there existing successful apps that lack significant feature enhancements? Don’t be satisfied with just a wine list, give sommeliers a way to talk to their fans!
Will the app be highly interactive? Let’s face it, most of us have the attention span of a flea. Successful games and utilities engage the user by requiring action!
