Ross Waycaster designed the first of his four mobile applications as a high school senior in Tupelo, Miss., a game called "Super Marrio Jump" that's been downloaded from the Apple store more than 20,000 times, earning him more than $16,000.
"I have an entrepreneurial spirit, so we'll see where that takes me," said Waycaster, 21, who's now a junior at Mississippi State University in Starkville.
It could lead him to a top-paying job in a sizzling new industry, one that might provide the United States with a big opportunity to increase its exports in coming years. While the overall economy still lags, the "app economy" has created nearly 500,000 U.S. jobs since 2007, when there were none.
Companies even worry that the nation isn't moving fast enough to produce new talent for thousands of unfilled jobs as consumers demand more and more gizmos and gadgets for their smartphones.
As a result, salaries are rising quickly: Mobile apps developers can expect pay increases of 9 percent next year, among the highest of any jobs, putting them in the range of $92,750 to $133,500 a year, according to a survey by the staffing and consulting firm Robert Half International.
Curbing the trade deficit
If the United States can maintain its dominance in the industry, many say the app economy could make a big dent in the country's trade deficit. Last year, for example, more than 20 percent of the apps downloaded in China were made by U.S. developers.
"There is unprecedented opportunity for America to capitalize on exploding international markets," Peter Farago, the vice president of marketing for Flurry, a high-tech startup company in San Francisco, testified in September before the House Subcommittee on Commerce, Manufacturing and Trade.
