This looks interesting but I first went to the link and couldn't figure out what it was. Shouldn't you put the description you have here on the landing page?

The first thing I see is "Book the Test", "Data Hub". What?

Also, instead of leaving how to use the data up to the imagination, I expect you can get an accurate VO2 max from this. If that is so, that would be worth mentioning since I don't think there is an alternative easy way to get an accurate VO2 max measurement.

Also, VO2max is a very marketing-oriented indicator! But you’re right: the most accurate way to measure VO2max is breath-by-breath gas analysis during a maximal test. Wrist wearables (Garmin, Apple Watch, etc.) infer VO2max from HR/pace/power models it's convenient, but estimates and sport-dependent. Running vs cycling VO2max can differ for the same athlete.

Our device measures breath-by-breath VO2, VCO2 in real time and resolves individual breaths, which may unlock new respiratory metrics for researchers. The accuracy of threshold value measurements is equally important: ventilation threshold 1, ventilation threshold 2, tidal volume etc.

Sorry, this page isn't ready yet. The main page only has basic info. We've got a really tech team (4x PhDs) and we're testing real athletes and doing research, but that makes sense, and we'll definitely add more later! Thanks for your comment!

Really cool direction. Love seeing VO₂/CO₂ tech get smaller and more accessible.
