Built for men who demand more from their bodies — and their data. VO₂ max tracking, strain scoring, testosterone proxy signals, deep recovery analytics, and cardiovascular intelligence calibrated to male physiology.
Every algorithm in Bionic Adam is calibrated to male physiology — giving you numbers you can actually act on, not averages pulled from female-majority datasets.
Bionic Adam measures cardiovascular and muscular strain across every workout and daily activity. Your Strain Score (0–21) scales with effort and is balanced against your recovery status to recommend whether to push, maintain, or rest — so you peak when it matters most.
VO₂ max — your body's maximum oxygen utilisation rate — is the single best predictor of long-term cardiovascular health and athletic potential. Adam tracks yours continuously using HR and movement data.
Your daily Recovery Score (0–100%) synthesises overnight HRV, resting HR, skin temperature, and sleep quality to answer one question: how much of your body's capacity do you have access to today?
Adam establishes your personal HRV baseline over 2–4 weeks, then alerts you when you're trending above (primed for a big effort) or below (body under stress — hold back). Your baseline, not population averages.
Deep sleep is where testosterone is released and muscle protein synthesis peaks. Adam tracks your deep sleep duration and quality with specific performance recovery thresholds based on male physiology research.
Based on your strain history, recovery trends, and goals, Adam suggests how to distribute your training load across the week — automatically adjusting when you're underrecovering or when a window of high readiness opens.
While Adam can't measure testosterone directly, it detects the combined HRV, resting HR, and sleep signature that correlates with high vs. low testosterone states — validated against morning blood serum tests in clinical study participants.
Continuous resting HR monitoring with long-term trend analysis. Atrial fibrillation detection. Blood oxygen saturation. Irregular rhythm alerts. All calibrated to male cardiovascular reference ranges.
Bionic Adam's algorithms are trained on datasets where male physiology is the primary subject — not an afterthought in a mixed-gender study.
Four finishes for every style. Grade 5 Titanium. Sizes 5–14. 3.5g. Built for everything you put your body through.
I've worn every major sports wearable on the market. Bionic Adam is the first one that told me I was overtraining before I got injured. The overreaching alert came on a Wednesday. I backed off. By Saturday I had my best long run in a year.
The recovery score saved my season. I used to just train hard every day. Adam showed me I was accumulating debt — my HRV was tanking every week. One month of following its recommendations and my bench went up 15kg.
As a cardiologist I'm sceptical of consumer wearables. The VO₂ max estimation on Bionic Adam is within 4% of our lab treadmill results. For a ring, that's extraordinary. I now recommend it to athletic patients as a primary tracking tool.
