Want to exercise your mind and your body simultaneously?

There's an app for that.

Louisville, Ky.-based Humana Inc. is launching the first of several iPhone applications that are designed to promote cognitive health and physical activity.

Available at the iPhone App Store for $2.99, Colorfall requires players to arrange cascading colored tokens in the order of the colors of the rainbow. Players can rack up higher scores by walking around and snapping pictures with their iPhone cameras and incorporating them into the game.

The game, which is part of Humana's Games for Health program, was produced in partnership with Persuasive Games L.L.C., an Atlanta-based company that designs computer games for social change, instruction and persuasion.

“We're excited to be the first health insurance company to offer people fun, healthy mobile games that challenge their minds and bodies while encouraging healthy behaviors,” Paul Puopolo, Humana's director of consumer innovation, said in a statement.

In addition to its healthy iPhone games series, Humana offers a host of free mobile services and smartphone applications for health plan members. They include an application that enhances a person's ability to make health care decisions at the point of service, such as finding urgent care centers; check their health care account balances; and get instant access to the information found on their member identification cards.

Additional mobile applications are in the works and will be released throughout the summer.
