Calibre Breath Metabolic Tracker

Calibre was inspired by a belief that access to meaningful, reliable data can improve everyday health and performance. Calibre packs a suite of gas and pressure sensors into a tiny, portable, wireless electronics module that clips to a comfortable face piece. It is comfortable, functional, aesthetic, and lightweight, featuring adjustable Velcro tabs and the right pressure for a comfortable fit around the nose and mouth. A precise tracking app visualizes the data from multiple gas sensors to measure composition of breath flow in real time.
