PROVIDENCE – Web-services firm Creative:Interactive Inc. has released a Red Sox opening-day countdown iPhone application.

The app displays the number of days, hours, minutes and seconds until the first games of Spring Training and Opening Day. The Red Sox will open their season at home against their rival, the New York Yankees, on Sunday, April 4.

The application also features a slideshow of photos of Fenway Park and Red Sox team members. Half of the proceeds from the 99 cent app will be donated to the Red Sox Foundation.

The mission of the Red Sox Foundation is to serve the education, health, recreation, and social service needs of children and families in New England. Since its establishment in 2002, the foundation says it has become one of the most successful charities in Major League Baseball in addition to being the largest professional sports charity in New England.

Creative:Interactive also offered another charity-related service in November 2008, when it created an online Ocean State Trivia game, the proceeds of which were donated to the Amos House, a nonprofit social-services agency.

Creative:Interactive, Inc. was founded by Ian Bohorquez in 2001 in New Hampshire. Bohorquez, who is a graduate of the Rhode Island School of Design, moved the company to Providence in 2006. Creative:Interactive has a number of well-known clients including The TJX Companies Inc., as well as other firms in the fashion, financial, travel, entertainment and technology industries.
