Calm Stone
See yourself calm.
Stress can be hard to recognize until you're already feeling overwhelmed. Calmstone gives you a simple way to slow down, practice relaxation, and see how your body responds in real time.
What it is
Calmstone is a portable, handheld biofeedback tool that monitors palm temperature changes via an infrared sensor. As you relax and blood flow increases, the device provides visual feedback by changing light colors from red to white.
Who's it for
Ideal for individuals dealing with anxiety, chronic stress, or feeling overwhelmed. It is also an excellent tool for therapy clients and practitioners who want a tangible way to practice slow breathing, mindfulness, and real-time relaxation.
