We hope you'll never need One Scream  

But if you are in danger and cannot phone for help, we will detect your scream and send an automated message to 999, telling them who you are and where to find you.

One Scream has been developed to only respond to genuine panic screams. Just as your own ear hears real distress, our app can also distinguish a true panic scream from other screams and sounds.


A  PANIC SCREAM  is a woman’s natural response to danger. A scream is a universally recognised primal sound that humans make when in distress to call for help.
