NEW YORK (Reuters Life!) - Fifty years after John F. Kennedy's inauguration, a new iPad application dedicated to the late president's life aims to be a multimedia museum for history buffs.

The app, by New York City-based historian and publisher Marc Schulman, includes a new biography titled JFK History Maker - A Fifty Year Retrospective as well as photographs, video and audio clips, the text of major addresses, letters, and his calendar.

The paper book is limited, in that you can't see all the supporting documents, videos and photographs, said Schulman, who simultaneously created the app as he was writing the biography.

Schulman gives the example of someone wanting to learn about Kennedy and civil rights. The user could look into his meetings on the issue and how much time he dedicated to it, watch video clips and read the full text of Kennedy's speeches.

There are lots of different levels. With the app you can really dig deeper, and do your own research, you don't have to rely just on my voice as the biographer, said Schulman.

The app, JFK Historymaker, was released this month. Schulman's Civil War app, which was published last summer, is being used in schools, he said.

Kennedy remains the most popular modern U.S. president. A November Gallup poll found that Kennedy continues to earn the highest retrospective job approval rating -- 85 percent -- from Americans.

One thing I've really come to appreciate over the years of researching him is that JFK was an extraordinary president, and not just because he was assassinated, Schulman said.
