Calibre Breath Tracker in Use at the Gym

Breath Calorimetry: What is it?

Calibre™ is the first wearable of its kind, but the science behind it is well known and established. Breath measurement is considered by medical experts as one of the most accurate ways to understand your body but has been widely unknown to the public.

Breath calorimetry, a.k.a. indirect calorimetry, measures gas exchange (oxygen intake and carbon dioxide output), which is then analyzed to determine the amount of energy and type of nutrient fuel used at any given time.

Long story short: your breath says a lot.

So why Calibre™?

While breath calorimetry has been relied upon for decades, there was no easily accessible device for ordinary people to use in order to tap into this biometric gold mine. Historically, this type of data could only be found in high-end sports labs and hospitals, where subjects would be tethered to tubes and heavy equipment. The entire process would be expensive and inconvenient, only available to competitive athletes or special patients.

Enter Calibre™: the first wearable fitness and metabolic tracker using real-time breath calorimetry.

Measuring 50 times per second, Calibre™ reads and captures oxygen intake, carbon dioxide production, respiratory flow & volume, and more. Taking these measurements and complicated formulas, the Calibre™ app is then able to help determine a multitude of metrics like the calorie burn rate, %carb vs. %fat burned, and minute volume, VO2, and more.

Calibre™ is designed to be used anywhere, anytime, and by anyone.

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.

Unlock the data in your breath and master your respiratory metrics and metabolism.
