Health bracelets and health trackers are all the craze now. People love being able to conveniently track their steps, mileage, and other health info right on their wrist. Well now, health tracking just became a little bit more convenient with Spire, a health tracker that attaches directly to your clothes. How does it work? Well, Spire uses respiration to track health data. They state "Respiration is the only autonomic function you have direct control over. Spire feeds your breathing data to algorithms that de-noise and classify it according to the way you normally breathe (what's calm for you is different than calm for another person)."
