Frequently Asked Questions

We replace estimates with exact measurements. Using breath-by-breath analysis, the device directly tracks the oxygen you consume and the carbon dioxide you expel. This raw data allows us to pinpoint your exact VO2 Max, Ventilatory Thresholds (VT1 and VT2), and fat-to-carbohydrate burn ratio at any intensity.

No. You use the mask for periodic assessments. The app then uses that precise baseline to set your zones and guide your daily, mask-free training via your phone, smartwatch, or tablet.

Yes, the PeakVO2 app pushes your dynamic zones to platforms like Garmin, Coros, Apple Health, and Strava.

No. But we believe you deserve access to the same tools that elite athletes use. Whether you are chasing a podium or simply optimizing your longevity, Peak VO2 provides the physiologic dashboard you need to benchmark your baseline and build a better engine.

Standard watches estimate, we measure. Watches and rings rely on optical sensors (PPG) to track heart rate and GPS to track pace, feeding that data into predictive algorithms to guess your oxygen consumption. Peak VO2 uses direct, breath-by-breath gas exchange—physically analyzing your actual O2 and CO2 ratios. It’s the difference between guessing your horsepower based on the speedometer, and plugging a diagnostic scanner directly into the engine.
