The French government has launched a free smartphone app to alert users about possible security incidents, including all major natural, technological and terrorist-related risks. Users will be able to view alerts for up to eight geographical areas. The app, called SAIP (Système d’alerte et d’information des populations), is available in English and French. You can download the app by entering the term ‘SAIP’ in the Apple App store or Google Play
