Got an idea for a mobile app? Now is the time to cash in on that idea. According to Gartner, Inc, consumers will spend $6.2 billion in 2010 and mobile application revenue is predicted to grow to $29.5 billion by the end of 2013. That’s an increase of over 450% making the mobile app industry one of the fastest growing technology industries since the internet boom of 2000.

Success stories of mobile developers making fortunes off apps have emerged almost overnight. Stories like that of Ethan Nicholas, whose iPhone app iShoot earned him over $900,000 in eight months. Stories like that of Ge Wang, owner of Smule, who reported iPhone app profits of over $1 million for 2008. In addition to these stories, the Android has proved itself equally as lucrative for developers like that of Kim, a former Volkswagen engineer and co-founder of San Francisco-based startup Picwing, who now earns over $13,000 each month off an Android app called Car Locator.

“The mobile app market is somewhat of a gold rush right now and small time developers are making big fortunes off of relatively simple applications. It is truly amazing to see mobile app developers become millionaires in the matter of months,” says Andrew Gazdecki, president of GetAppQuotes, a company specializing in connecting entrepreneurs and companies with mobile app developers.
