As part of its ongoing work to end violence against women and offer violence prevention and intervention tools, YWCA Canada, the country’s oldest and largest women’s multi-service organization, announced today the launch of the YWCA Safety Siren app. The unique safety siren is activated with a press of a button or a quick shake and turns an iPhone or iTouch into a multi-functional safety device. Part of YWCA’s Power of Being a Girl anti-violence initiative, the app is available for free in the App Store.
