RequestSOS is a medical emergency alarm that when activated, alerts people nearby to your location so that they can help you in the event of a medical episode.
Simply open RequestSOS from the iOS app or on your Apple Watch and activate the emergency alarm to alert people around you to your location. The alarm will even be activated from your Apple Watch when your iPhone is locked!
Once the alarm sounds, the alarm screen will display information about you, your medical conditions, your medication and any contacts you have added, with the ability to contact them. This allows anyone around you who hears the alarm to help you in a medical emergency and inform paramedics about your conditions on arrival.
