One Scream is a new handsfree personal safety app for women and teenage girls that can stay with the user wherever she goes.

If the user panic screams (a louder, more complex sound than any other), the app detects it, even when the phone’s across the room or buried at the bottom of her bag. 

Once a panic scream is detected, the phone vibrates and plays back a loud siren before an alert is triggered. The user has 20 seconds to cancel it if she is safe. 

One Scream then sends a message with her name and location to whoever she chose for support. The phone line stays open so she can speak hands-free.


When my children started attending school emails containing warnings to be vigilant during school runs suddenly became part of my life.

Conversations about muggings and the feelings of helplessness and fear that those life changing events can leave behind were exchanged among mums. 

In 2015, I initiated the development of an app to help women in those situations where she has no viable option to make a call to ask for help. One Scream was born.

It feels great to turn something dark into a force for good!

Even from a young age, girls can begin to modify their behaviour. By making women feel safer they have more agency over deciding where they will happily go alone, what to wear or how late they should travel.


"I envisioned One Scream to be an uncomplicated, invisible helper that is there for you to feel safer or even get help fast if you need it. It is not another monitoring app intruding your life, watching every step you do."
