My experiences with the Calibre Biometric Tracker (regular VO2Max and FatMax testing)
1 week ago (edited)
I ordered the Calibre Biometric Tracker (US) from Germany and will receive it today (shipment duration approx 10-12 days with default Fedex shipment option). My goal is to analyze VO2Max and FatMax in the context of cycling on a regular basis. If any of you are interested in the device, feel free to ask questions or comment on your experiences here.
By the way, ordering directly from Calibre Biometric (US) was easy, but keep in mind that you will have to pay additional import duties and processing fees. For me, that was 102.29 EUR. But still a fair investment compared to VO2Master or similar devices. I am looking forward to my first test sessions.

€443,95 EUR + 100 EUR + in fees sounds a lot but FatMax and RMR (Resting Metabolic Rate Protocol) are special and maybe worth the money... I´d love to have a good VO2Max Tracker that i can wear all the time... What do you all think about the Apple Watch VO2Max Tracking quality?
@andy O2Max numbers from smartwatches are only "calculated" base on heart rate (and performance metrics, e.g. power measurement on the roadbike). If you want real numbers you must use a device based on respiratory gas analysis.
Curious to hear how satisfied you are with it! It would be great to compare it against a proper spiroergometry test at some point to gauge its accuracy.
I did one on an ergometer at years.co two weeks ago, but to be honest, it wasn’t the best experience given my current training routine. I usually lift heavy weights twice a week and do 2x Zone 2 and 1x VO2max interval run per week, so using a bike felt quite off. My legs got sore quickly since the stimulus was very different from my usual training, mostly targeting my lower body.
In Germany, a lab-based spiroergometry usually costs around €199–259. So if the device turns out to be within 3–5% accuracy of that, it would still be a really solid value.
