PITTSBURGH — Pittsburgh Steelers cornerback William Gay is working with a women’s shelter to promote the national debut of a mobile app designed to help victims of domestic violence.

The “RUSafe” app has been available in Pittsburgh for several months and will be made available nationally on iPhones and Androids beginning Nov. 1. The free app, designed by the Women’s Center & Shelter of Greater Pittsburgh, gives users a brief questionnaire and uses GPS technology to help the user locate the nearest domestic violence hotline or 911.

The app has already been used 1,000 times and helped more than 20 victims in Pittsburgh get the help they need.

Gay has become a leading advocate for domestic violence victims in recent years. His mother, Carolyn Hall, was killed by her husband when Gay was a child.

“She didn’t have a chance or someone to help her or a hotline to call,” Gay said.

Gay praised the NFL for taking a harsher stance on domestic violence following Baltimore Ravens running back Ray Rice’s indefinite suspension for hitting Janay Palmer.

“I’m just glad we’re talking about it from the top of the league to the bottom,” he said. “Our goal is always to try to broaden or get the awareness out everywhere.”
