This personal safety app for iOS and Android is aimed at preventing attacks and safeguarding evidence of any incident. Once downloaded on a smartphone, the user simply touches “record” and the service broadcasts audio/video clips and automatically uploads the data to a secure cloud server. The video does not stay on the phone, so there's nothing any attacker can do to erase it. The app can also directly contact emergency services in 146 countries.
