DOMINO application is developed as part of the EU-co-funded DOMINO project (DOMINO - Educational Mobile Application for Prevention of Domestic Violence). DOMINO project aims to provide knowledge and education for current and future social- and healthcare professionals in Higher Educational Institutions (HEIs) for prevention and early intervention of domestic violence by developing an educational DOMINO mobile application. The longer-term aim is to improve the physical and mental well-being and care of victims and perpetrators by improving the early intervention and prevention of domestic violence. The application was developed in close cooperation with social- and healthcare specialists, allowing the application to have carefully selected methods and tools to teach and prevent domestic violence.
