Doodle Zombies is a game for iPhone users in which a player hunts zombies.

“People like it, I guess,” he said. “It’s cool because you can voice chat with other players, and you can play in multiplayer [mode].”

Negotiating work contracts can be tricky, Alex said with a smile, revealing braces.

“I don’t like to tell people how young I am,” he said. “I’m 14, and I feel like they won’t take me seriously.”

But he has serious business initiative.

When Apple’s iPad came out last spring, Alex anticipated that users would want shiny new apps for their shiny new tablets, and he created Chalk—an app that simply allows users to draw on a virtual chalkboard with a virtual stick of chalk—which was listed as one of the top 100 selling apps for the device and made it to the Apple Store’s front page in April.

“With Chalk, it was mainly a hit because it was one of the first ones out there,” he said. “I try to do, like, three apps a season, and two or three games throughout the year.”

He added: “I started off doing mostly games, but I think it’s easier to get noticed if you have a utility or a photo application.” He recently launched Photo Booth Plus, an application that allows users to paste new or archived pictures from their iPhone’s photo library into a filmstrip background and upload them to Facebook and Twitter.
“Facebook and Twitter apps are huge,” he said.

While he has had successful sale figures, Alex said he views his program development as more of a hobby than a job.

“On the weekends, I try to do my homework pretty early in the morning, and then I spend like two or three hours a weekend on this,” he said.

The rest of his time is dedicated to being a ninth-grader.
