See What Customers Are Saying

“As a medical professional who performs respiratory testing and breath calorimetry in a hospital - as well as an exercise enthusiast - I am absolutely thrilled with Calibre. I think this is one of the most exciting innovations in personal wearables we have seen in years…” 

— Karla S. (Beta Tester) Senior
  Clinical Exercise Physiologist

“It is awesome to have this sort of data. Clients ask me all the time how many calories I think they burn, and I can’t give them a concrete answer. Measuring caloric burn rate through breath like Calibre, that is the most accurate way to know.”

— Mike G. (Beta Tester) Owner and Head Coach Fit4 Personal Training

"I have been devoted to exercise, nutrition and metabolic wellness a for many years, and I can say that Calibre is hands down the most accurate and insightful metabolic tracker  to hit the market. It gives you real-time markers that, as far as I know, no other wearable can measure. And it's so lightweight and breathable, you could almost forget you're wearing it."
