STOP THE SPIRAL IN SECONDS. When a panic attack hits, you don't have time to navigate complex menus or watch a 10-minute meditation. You need a rescue tool that works now. panic.btn is a "digital first aid kit" built by Eric (Franz) Richers, a Licensed Professional Counselor (LPC) and addiction specialist. It is specifically designed to provide immediate physiological intervention when your nervous system is overwhelmed. WHY PANIC.BTN? Unlike "zen" lifestyle apps, panic.btn focuses on the science of the "Physiological Sigh" and grounding techniques used in clinical therapy to lower your heart rate and cortisol levels instantly. KEY FEATURES: The Rescue Button: One tap launches a guided grounding sequence. Clinical Breathing Tools: 4-7-8, Box Breathing, and Vagus Nerve resets.

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.
