Nevou Band
On your wrist, day and night. Reads HRV, resting heart rate, sleep stages, SpO₂ and movement — the raw signals of how recovered you really are.

We show our
working.
Every score opens into the arithmetic that produced it. And when we have not measured enough, we show you nothing rather than a number we have not earned.
Your health data belongs to you. Always.
HRV 62ms
Sleep 7h32
Strain 12.4
Most scores are a black box.
Ours opens.
A recovery score of 61 tells you nothing on its own. Tap it and you see every part that made it: how much came from the variation between your heartbeats, how much from your sleep, how much from your resting heart rate, and which signal was missing that night.
One system. Three parts.
Built to work as one.
A band for your nervous system, a scale for your body, an app for the meaning. Each is good alone. Together, they see the whole picture.
Nevou Pod
A smart scale that reads more than weight: body-fat percentage, muscle mass, water, bone, and segmental balance — left vs right, arm vs leg.
Nevou App
The intelligence. It turns every signal into Recovery, Strain, Focus, Stress and your personal circadian rhythm — and explains each one in plain language.
Your day, modelled
Drag through your rhythm.
Nevou forecasts your energy across the day from a three-process model of alertness — then shows what you actually lived. Scrub the curve.

The morning verdict
Recovery, with the receipts.
Each morning Nevou weighs your overnight HRV against your own baseline, your sleep performance, and your resting heart rate — and tells you how much your body can take today.
- HRV vs baseline — the dominant signal of readiness
- Sleep performance — depth, REM, and time asleep
- Resting heart rate — how settled your night was

The engine
Science you can trust the why of.
Nevou's scores aren't arbitrary. They're built on the published physiology of the nervous system and sleep — then tuned for one honest read each day.
🌙
Three-process model
Your circadian forecast combines homeostatic sleep pressure, the body clock, and sleep inertia — the same framework sleep scientists use (Borbély; Åkerstedt & Folkard).
💚
HRV-led recovery
Readiness is led by ln(RMSSD) against your personal baseline — the most reliable overnight signal of autonomic recovery — with sleep and resting HR.
🔥
True cardiovascular strain
Strain uses Banister's TRIMP with exponential heart-rate-reserve weighting, so a hard hour counts far more than an easy one — compressed to a simple 0–21.
Every score links to a plain-language explanation of how it was computed.
The part nobody advertises
Here is what it does not do.
Every tracker has gaps. Most fill them with a number and hope you do not check. These are ours, in writing, before you buy anything.
Nothing at all for three days. Your body age estimate shows no number until day three, and we do not call it established until day twenty one.
Nothing, rather than a low score. When a night is too thin to score, recovery returns nothing at all instead of a number we would have guessed.
A written sentence, not a zero. A night we could not read shows a plain empty state, never "0 out of 100, poor".
A gap stays a gap. Sixty minutes without the band on breaks the line and draws the gap, instead of quietly joining the dots across it.
We tell you how we know. Food you weighed, food you scanned and food estimated from a photo are each marked differently, and a meal only counts as precise when every item in it is.

Good questions
Frequently asked
What exactly is Nevou? +
Nevou is a connected health system: the Nevou Band (a wrist wearable for recovery, sleep, HRV and heart rate), the Nevou Pod (a smart scale for weight and full body composition), and the Nevou app, which unifies everything into clear daily guidance — and explains the reasoning behind each number.
How is it different from my watch or other apps? +
Most apps and watches show you what your numbers are. Nevou explains why — it links recovery, sleep, strain, body composition and nutrition into one model and makes a single, honest call about your day.
What does Nevou measure? +
Recovery, heart-rate variability (HRV), resting heart rate, sleep stages, SpO₂, daily strain, a personal circadian rhythm, plus weight, body-fat %, muscle mass, segmental balance, body age and nutrition.
Is the science legitimate? +
Yes. The engine is built on published physiology — a three-process model of alertness for the circadian forecast, ln(RMSSD)-based recovery, and Banister TRIMP for strain — and every score links to how it was computed.
Is my data private? +
Your health data belongs to you. Nevou is privacy-first: keep, export or delete your data at any time.
