Prana is the first wearable combining breath and posture tracking in one compact device for reducing stress. Building on recent medical studies and ancient Yoga traditions, Prana supports the interconnection between good breathing and good posture. By monitoring breath patterns, diaphragmatic breathing, and posture, Prana offers a new holistic view into the quality of our breathing, and provides tools to change it for better health. Prana is a sleek and stylish tracker worn near the waist, and connects to most smart phones to provide a gamified engaging app experience. Prana offers both passive tracking and active training modes so that you can learn how you currently breathe and sit, and then do something about it to actively improve these vital aspects of health.
