Lab-grade accuracy at a fraction of the cost.

Tech has gotten more capable and less expensive, but not much has changed with existing respiratory and metabolic measuring devices.

Calibre took the gold standard method, breath calorimetry, coupled it with a new disruptive design and created a game changing device that perfoms to the standards needed in a research performance lab yet was able to price it at a fraction of the cost.

Issues with traditional metabolic carts

For years, healthcare professionals and athletes relyed on metabolic carts to monitor oxygen consumption (VO₂), resting metabolic rate (RMR), and other vital metrics. While some are accurate, these systems are often:

Expensive:

With prices starting at tens of thousands of dollars, traditional carts are cost-prohibitive for many.

Complex:

They require extensive calibration and specialized training to use.

Bulky:

These large devices are only practical in labs or clinics.

Limited in Scope:

They can’t easily scale to reach broader audiences due to their complexity and high costs.

Calibre Biometrics: smarter, simpler, more acessible metabolic cart

Whether you're a professional in the respiratory and metabolic field or a consumer who's spent time and money on tests in a lab, Calibre gives you a cost-effective and easy way to access this valuable data on your own terms.

If you're just starting to explore personal data collection—like learning about VO2 Max as a key indicator of longevity—or maybe you're curious about tracking your metabolism regularly, you'll find that a single lab test can cost as much or more than Calibre.

With Calibre, you can use the device whenever you want, as often as you need, giving you more freedom and insights.

Precision you can trust

Although relatively new to the market, Calibre has certainly demonstrated its ability for acuracy. Calibre was included in a published study done by Maastricht University that was conducted to test the accuracy of multiple respiratory and metabolic devices. You can see in the graphs here how well Calibre stood up against most of the well known (all more expensive) devices in the market.
