A new piece of technology aims to curb the number of victims of sexual and violent crimes across the globe every day. The Whistl case, which is currently at the funding stage on crowdsourcing platform Kickstarter, connects to a smartphone (specifically the LifeShel app) to deter foes and warn friends of any danger. The gadget comes with three crime deterrents – a 120dB alarm, a 90 lumen strobing LED and automated message alert. CEO Jayon Wang, who leads the US-based LifeShel team of so-called “survivors and engineers”, explains more about the safety device.


Was it a personal experience that inspired to create Whistl?
Whistl's concept was a result of our engineering team responding to the attempted assault of one of our close friends Leah Yingling (she is now LifeShel's Director of Community Outreach). Also we we began to see opportunities for community safety arise from the data our smartphones are generating.


How can the gadget deter the assailant?

The LED has the capability to blind an attacker if shined directly into his/her eyes. The noise alarm is intended to scare assailants away by attracting attention to the incident.

That's why you choose the name Whistl?
Yes, we intend to replace every old rape whistle with our smartphone age Whistl case.

Is it easy to deal with the panic mode button even when frightened?
Absolutely. We have designed the button to be a press button, that requires intentional force to set into panic mode.

And what is the efficiency of this gadget? Is it really reliable?
The main efficiency is the exterior, with its easy to access emergency button. It's never been implemented before to have a single button initiate an emergency response with data delivery.
