RUSafe is a free dangerous relationship assessment app serving the continental United States. RUSafe invites the user to answer a series of questions about her/his relationship. The app then calculates the responses and, if there is cause for concern, it will enable the user to directly call the Domestic Violence Hotline nearest them. If the user is in immediate lethal danger, she/he can call 911 directly from the app. RUSafe is based on the Danger Assessment developed by Jacquelyn C. Campbell, PhD, RN, FAAN of Johns Hopkins School of Nursing. Learn more at www.RUSafe.net.
