    Silent wake at the right moment

    VEYRO senses the end of a light-sleep cycle and vibrates instead of an alarm. No cortisol spike, no groggy hour.

    Recovery briefing over espresso

    HRV is up 12% vs. baseline. The app flags her as ready for high-stakes work — board call and term-sheet review get moved to the morning.

    Stress nudges before the meeting spirals

    A subtle haptic during back-to-back calls cues a 90-second breathing protocol. Continuous skin temperature confirms the drop.

    Readiness gate

    Resting HR is 4 bpm above baseline and HRV is suppressed. VEYRO converts today's planned intervals into a Zone-2 hour. Injury avoided.

    Live load, not guesswork

    Heart-rate strain and SpO₂ stream to the app. Pace targets adapt every 5 minutes so he stays under the lactate ceiling.

    Recovery window quantified

    Body temperature elevation and breathing rate map a precise refuel window. Carb timing, cold plunge length and nap duration come from the ring.

    Taper, perfected

    Four weeks of trends predict peak readiness for Sunday 07:00. Diego sets a personal best by 4 minutes — and beats it again next race.

I don't believe a protocol until VEYRO shows me the delta. The ring is my null hypothesis.

    Establish the signal

    Seven days of untouched data — sleep architecture, nocturnal HRV, skin temperature, SpO₂ — set a personal baseline before any intervention starts.

  2. 02Protocol A

    Magnesium glycinate, 21 nights

    Deep sleep grows 23%. Resting HR drops 3 bpm. VEYRO surfaces the delta against baseline with statistical confidence, not vibes.

  3. 03Protocol B

    Sauna 4× per week, 8 weeks

    Resting HR continues to drop. HRV trend climbs into the top decile for his age band. The ring quietly verifies what the literature predicted.

  4. 04Quarterly review

    What to keep, what to cut

    AI summarises 90 days into a one-page report: keep magnesium, keep sauna, drop late caffeine. Compounding gains, zero guesswork.
