Tammy developed an app that discreetly calls for help when you say a specific word. Can an app that’s always listening keep people safe? And more importantly, is that cool?

“This app is hard to detect and easy to use. And because you record your own word and program your own alert partners, your assailant will never know that help is on the way.”
