Unveiling at CES 2027 · Las Vegas

Days Hours Minutes Seconds

Get to Know your macros utilisation without manual intervention

Your daily macronutrients made simpler, measured against your goals.

The EyvaX band seen straight on: the four-lobed module on its mesh strap.

Energy balance score

Your day, in one number. Your reasons, in four.

What you ate, how you slept, how you bounced back, how hard you pushed. One score, measured against your baseline.

  1. Four plates from above: sliced grilled chicken breast with kale, a broccoli and berry salad, avocado with nuts and olive oil, and quinoa with roasted sweet potato.

    Nutrition

    Nutrition 79

    Your macros and hydration, read from your body, not your meal log.

    79+4 vs usual

  2. Mountain climbers on a mat in a garden, the EyvaX band on the wrist.

  3. Sitting cross-legged on a garden lawn, eyes closed, the EyvaX band on her wrist.

    Rest

    Eight hours in bed isn’t eight hours of rest. This shows the difference.

    72−4 vs usual

  4. Swimming front crawl in an outdoor pool, the EyvaX band on the wrist.

    Recovery

    Did yesterday clear? Your heart’s small signals know before you do.

EyvaX on people

Wear it where you work hardest.

On the road, on the bike, under a bar. Light enough to forget mid-set, and reading you as closely at full effort as it does at rest.

          EyvaX

          A wellness coach, not a doctor. It won't diagnose, discuss blood sugar or medication, and it points you to a clinician when that's the right answer.

          One score, scoped to the window you're in.

          Four windows a day, each weighing a different set of signals — always against your own baseline, never a population average.

          EyvaX app home in the morning window: Energy Balance 70, driven by last night's sleep.EyvaX app home in the noon window.EyvaX app home in the evening window.EyvaX app home in the night window.

          Last night decides this number. Sleep leads, and EyvaX reads the depth and continuity of it before you've done anything at all — so the day opens with a target rather than a verdict.

          The product

          Sculpted to be forgotten.

          The EyvaX module from above: four rounded lobes on its mesh strap.
          1. 01 / Form

            A four-point body.

            Concave on every side, so it seats against the wrist instead of sitting on it.

          2. 02 / Finish

            Graphite, not gloss.

            A matte anodized shell that stays fingerprint-neutral through a full day of wear.

          3. 03 / Power

            Seven days, then ninety minutes.

            It drops onto the dock, the pins align magnetically, and it never misses a night.

          4. 04 / Fit

            Closes anywhere.

            Magnetic mesh with no notches, so sensor pressure stays constant on any wrist.

          Power

          Set it down. It finds the pins.

          Two gold contacts, one magnetic seat, and a halo that reads the state of charge from across the room.
