A voice activated safety app

even works in your bag

no need to press a button for help


Feel Save. Be confident

If you're in danger and can not reach your phone, your panic scream automatically triggers the app.

- A text message and an automated call with your location is then send to your nominated contact. 

- The phone line stays open so they hear what's happening and get you help fast. 

You'll feel safer and more confident just knowing that help is there, should you need it. 



How One Scream works

1.     Activate the app and leave it to run in the background of your phone.

2.    The red bar will let you know that the app is activated. 


If you are in danger and you cannot reach your phone

1.    your panic scream triggers the app - even when your phone is buried in your bag

2.    We then send an automated message to your chosen contacts              

3.    and create an open line for your helper to hear real events.    



“How Do I cancel an alarm?”

We have carefully measured the qualities that define a true panic scream.

However, if the alarm does mistakenly activate, you have 20 seconds to cancel it before your contacts are notified. A push notification and siren will alert you that the alarm has gone off.


“Does the app listen to what I say?”

“One Scream can't understand words and the app does not record conversations; it is trained to detect panic screams only.

One Scream also doesn’t track your location.

We built One Scream to make you feel safe!”


“What happens if someone next to me screams?”

You can bump into friends and laugh as much as you like - the app only detects a panic scream, which is a very specific and complex noise.
