The Companion app (http://www.companionapp.io) is a free personal safety mobile app created by five students from the University of Michigan, MI, USA. It enables users to invite friends or family members to monitor their journey and check their safety via an online map, without the need for their friends or family members to install the Companion app. Companion is available on both iOS and Android.
Companion’s key features include:
Invite friends or family members as companions.
Live Map – friends or family members virtually monitor the user’s journey.
Nervous Button – when the user feels at risk, but without an explicit need for police, user can press the nervous button to call the emergency contact directly.
Smart 911 – user calls the police via “911” button and the Companion app instantly shares the GPS location.
