Zansors makes medical-grade wearable health sensors and mobile apps to help capture your personal health analytics. Our technology is evidence-based and developed in conjunction with medical researchers, clinicians and biostatisticians to identify and treat real health problems. Zansors’ wearable health sensors and apps are tools, not toys. Many of today's health trackers are toys—they may provide interesting information, but often it's inaccurate and doesn't help you resolve your health issue. Our sensors and apps are clinically-tested and allow you to tune into your personal bio-signals and privately collect and interpret daily data from your body. Our products help you to know yourself and improve your health easily, affordably, and privately. Respa has been released! Check out our IndieGoGo campaign to see the world's first acoustic breathing sensor: 5e.fnd.to/respa For more information on Zansors, visit us on the web at www.Zansors.com or call us at 571.303.1915.
