Know BeforeYou Train

Active physiological testing shows how you start, respond, and recover— measured against your own baseline, not population averages

Early access
COR5 wearable device

Cor is Latin for heart. 5 represents the five sensing modalities at the core of the platform. Five signals, fused into one picture

  • 1Cardiac
  • 2Vascular
  • 3Composition
  • 4Thermal
  • 5Motion

Measured together. Interpreted through your personal baseline.

WHY COR5

Because performance is not one signal.

  • MultiMulti-frequency BIA — body composition
  • 5Sensors fused in real time
  • 1Adaptive personal baseline per user
  • 10About 10 days to establish your initial personal baseline

Every COR5 score is built from real sensor signals.

The active testing difference

Watching your body vs measuring how it responds

Active testing

Test. Train. Re-test

Measure before, during, and after training — against your baseline.

  1. Test

    State before training

  2. Train

    Response under load

  3. Re-test

    Recovery after training

Passive monitoring

Wear it. Wait for the score

Tracks sleep, activity, heart rate, and recovery — automatically.

  1. Background

    Runs automatically

  2. Context

    Sleep, activity, recovery trends

  3. Trends

    Gradual changes over time

COR5 COMPARES YOU TO YOU

Every metric interpreted against your personal baseline — not what a textbook predicts for someone like you

Your body has a physiological signature

COR5 learns the patterns that are normal for you — across cardiac, vascular, composition, thermal, and motion signals — and how those patterns change with training, stress, and recovery

A three-dimensional cloud of small points, shaped like a human torso, turns slowly against a dark background. Groups of points brighten and fade in turn, standing for the cardiac, vascular, body composition, thermal and motion signals that COR5 records, and they settle into one repeating pattern that belongs to a single person. The clip loops, has no sound and shows no on-screen text.

Explore yours

  1. Built from your baseline

    Repeated COR5 tests establish the ranges and relationships that are typical for you.

  2. Changes with your state

    Your physiological response shifts with training, stress, hydration, and recovery.

  3. Gets more personal over time

    Each new test adds context to how COR5 interprets what your body is doing today.

Your baseline tells COR5 what is normal. Your Physiological Signature shows how your signals work together

Two signals.
Captured together,
beat by beat

By synchronizing ECG and pulse wave, COR5 sees more than either signal can alone — giving you a clearer picture of heart and vascular response

From this synchronized capture, COR5 derives:

Two traces scroll steadily from right to left across a dark grid. The upper trace is an ECG: a flat line broken by a sharp, narrow spike at every heartbeat. The lower trace is the pulse wave measured at the finger: a smooth, rounded rise and fall that follows each ECG spike after a short, constant delay. The two traces stay locked to the same rhythm for the whole clip. The clip loops, has no sound and shows no on-screen text.

When your pattern changes

Repeated checks help COR5 spot meaningful shifts from your usual pattern

  • Track Next card

    Notice
    the change

    A change across multiple tests is more meaningful than a single reading

    Build your reference

    Repeated checks establish your personal reference range. As more results are added, COR5 can distinguish normal variation from a shift worth reviewing.

  • Locate Next card

    See where
    it appeared

    COR5 compares responses across rest, posture, training, and recovery

    See the context

    Identify where the shift appeared — at rest, during posture change, under training load, or in recovery.

  • Notify Next card

    Know when something
    changes

    You get clear follow-up — notifications, retest prompts, and trend history

    Review the signal

    When a result moves away from your recent baseline, COR5 can prompt you to repeat the check or open your history. Each new result stays connected to the broader trend.

  • Guide Next card

    Know what
    to do next

    If the change persists, consult a qualified healthcare professional for evaluation

    Decide on the next step

    Repeat the check under similar conditions. If the change persists, review the trend and consider sharing it with a qualified healthcare professional.

Performance Lab overview

COR5’s most advanced analysis system

  • Built for bigger
    questions

    Go beyond one test or one session. Select the data and timeframe, then ask what changed and why.

  • Not a fixed
    report

    No fixed date window or report template. The report is built around the data you select.

  • History-aware
    interpretation

    COR5 uses prior tests, trends, and selected reports to explain readiness, recovery, body status, and training response.

  • Coach-ready
    output

    Clear findings you can review, share, and use in coaching decisions.

Frequently asked questions

When will COR5 be available?

We have not announced a delivery date yet. COR5 is moving toward its first production release, and Early Access members will be among the first to receive updates as availability and reservation dates are confirmed.

What does joining COR5 Early Access mean?

Joining Early Access keeps you informed as COR5 moves toward launch and gives you priority notice when reservations become available. There is no purchase commitment required to join.

Do I need to pay anything to join Early Access?

No. Joining COR5 Early Access is free and does not require a deposit or payment. We may offer Early Access members the opportunity to reserve a device once our production timeline is confirmed.

Does joining Early Access guarantee me a COR5 device?

Not yet. Early Access gives you priority notice when reservations open. A device is only secured once reservations become available and you complete the reservation process.

Will COR5 require a subscription?

COR5 will offer different software experiences depending on how deeply you want to test and analyze your training. Basic will cover the core readiness, training, recovery, and trend experience, while Pro will add deeper testing and interpretation. Final subscription packages and pricing will be confirmed before reservations open.

Do I need to wear COR5 all day or while I sleep?

No. COR5 is designed around short structured tests and targeted measurement around training. You use it when the measurement matters rather than relying only on continuous passive tracking.

How long does COR5 take to build my personal baseline?

COR5 begins giving you useful context from your first tests and builds a more personalized baseline through repeated, consistent use. The current experience is designed around establishing that baseline over approximately 10 days.

Is COR5 a medical device?

No. COR5 is a wellness and performance product for athletes. It is not intended to diagnose, treat, cure, prevent, or monitor any disease or medical condition.

What do Early Access members receive?

Early Access members receive priority launch updates and priority notice when reservations open. If you later purchase COR5, your device will include 3 months of COR5 Pro at no additional cost.

What is COR5 Performance Lab?

Performance Lab is COR5’s most advanced analysis experience. It lets you select tests, ARC checkpoints, dates, and a report focus — or enter your own question — and generate a custom longitudinal report from your COR5 history.

What is Training ARC?

Training ARC connects your state before training, your response during the session, and your recovery afterward into one complete performance picture.

Can COR5 work without an internet connection?

Yes. COR5 can record and store data on the device when a connection is unavailable, then sync the data when connectivity returns.
