A mother and son from Brighton have launched an app to help keep members of the LGBTQ+ community safe on nights out. Luciana and Nicholas Cousin set up the Back Off. Back Up. (BOBU) app and it is currently operating in Brighton. The technology aims to provide safe spaces, such as bars and restaurants, where users can go if they feel in danger of being attacked. According to the charity Stonewall, hate crimes on the basis of sexual orientation have increased by 112% in the last five years. The app shows restaurants and bars where staff have been trained to support people who feel in danger.
