It is specifically designed to provide immediate physiological intervention when your nervous system is overwhelmed. WHY PANIC.BTN?

FROM THE FOUNDER: "I built this app for my clients to use between sessions. In a moment of crisis, you don't need a coach—you need a tool. panic.btn is that tool." — Eric Richers, LPC, MA, CADC III.
