We are truly the first device to democratize the use of the gold standard of metabolic rate measurement “breath/indirect calorimetry”* This science has been utilized and vetted for decades but simply has not been available due to system limitations, size and high cost.

Calibre has eliminated the barriers to access and finally made it possible to measure with ease and accuracy outside of a sports performance laboratory or clinical setting.
