Hands-free safety alarm   

Women and girls shouldn’t be afraid to go out alone, but you feel safer when there’s someone there to help if you need it. Partners, parents and friends can worry less too.

One Scream is a new personal safety app for women and teenage girls that can stay with you wherever you go. 

If you panic scream - a louder, more complex sound than any other - the app detects it, even when your phone’s across the room or buried at the bottom of your bag.


Just as you instinctively recognise a cry for help as opposed to a playful scream, so does the app.
