An iTunes application created by two University students has topped Apple’s charts in just two weeks on the market.

Hayden Kramer and Wesley Miller, juniors from Atlanta, developed Studio App, which sells for $7.99 and allows iPhone and iTouch users to record song tracks with their own vocals.

“The main function of the application is to record vocals through a microphone-type headphone, in real-time,” said Miller, a biology major. “You can sing, rap, or do whatever you like to do.”

With Studio App, users can choose from more than 30 instrumentals, or beats – some created by Kramer and Miller and others donated by producers worldwide, including Atlanta-based producers Lazy Mane and Kosherbeets. Users can record their voices over the beats and mute, delete or layer vocals in a single song.

“The average user may want to make songs for fun,” Kramer said. “But if [people] are serious, the producer and title [of every beat] is listed. We encourage users to look [producers] up and ask them if they want to collaborate.”

The application can be purchased through Apple’s App Store – an online database of applications for mobile devices. Studio App is a top seller in the United States, Canada, Europe, Japan and Australia. It is ranked No. 6 on the “Top Music Application” list and was featured in the “New and Noteworthy” section of iTunes.

“You get on the list based on how much money you are making,” Kramer said. “[The list] is updated every one or two days.”

Studio App has only been on the market for two weeks, but already 3,000 users have downloaded it to their mobile devices.

“Every day we get hundreds of new users and hundreds of people buy it,” Kramer said.

Though Kramer and Miller admitted they are making a decent profit off of the application, they did not want to divulge their total profits.

“We don’t feel comfortable releasing that info to the University,” Kramer said. “We’re not comfortable with people knowing.”

Kramer and Miller came up with the idea for Studio App in high school. They created a business, Krasidy LCC, so they could sell the idea to Apple.

“In high school, [we] had a computer with a mixer and [we] used it to record [music] for friends,” said Kramer, a nutrition science major. “We were doing it for fun. But [the beats] got circulated and people asked for $50 per track. We saw that there was a new demand for it.”

Originally the application was intended to be in the form of a Web site, but when Apple’s App Store launched, Kramer and Miller changed courses.

They started working on Studio App in August 2008 and finished it in December 2008. In those four months, Kramer and Miller had to go through a tedious process to publish the application.

“We had to go through the Secretary of State’s office,” Miller said.

He said they had to create a business and complete an article of incorporation, or written declaration, that they were chief executive officers of their business. They also had to pay a $125 fee to register the corporation with the state.

“We have to be credible and [Apple] checks to see if our company is real. The Apple Store is based on individual development,” Miller said. “You develop it yourself and Apple gets 30 percent [of the profit] because they market it, and you get the other 70 percent.”

Kramer said he and Miller are not sure if they will pursue app-making as a full time career, but they “do plan on making many other apps under the company.”

“We would like to keep the company going,” he said. “As of now, we would like to stick to [making] music [applications] because it is based on our interest.”

Despite the application’s rise to success, it hasn’t caused much change in the daily lives of Kramer and Miller.

“We haven’t gotten very much feedback,” Kramer said.

“Personally, the fact that we did this means a lot and is very encouraging. In my head it seems like there is no way me and my friend could pull something like this off, but we put forth an effort and we did it.”

The duo is currently working on an update to their current version of Studio App.
