Concept
Siren is an update for Siri, which acts as your personal guardian angel. With the Siren update, Siri can be programmed to respond to key phrases or words to send for help when the user is in a vulnerable situation. When a key phrase activates Siren, selected family members or the authorities are alerted of the distress along with the GPS location of where Siren was used.
