What Elio does, and what it does not do

Elio does

• Track heart rate - HRV, SpO₂, skin temperature and activity continuously.
• Offer heart-rhythm trace on demand and sleep / recovery insights in the Chutex app.
• Sync measurements via Bluetooth to the Chutex app (phone required for setup and detailed review).
• Connect data to Aria (AI coach), reports and recommendations.
• Host health data in France under GDPR.
• Work with the Elder vest and Vita scale in the same Chutex ecosystem.

Elio does not

• Detect or physically protect against falls at the wrist (Elder vest, sold separately).
• Provide a medical diagnosis or replace advice from a healthcare professional.
• Guarantee detection of arrhythmia, sleep apnea or cardiac disease.
• Replace prescribed medical devices (Holter monitor, medical oximeter, etc.).

What is a health smart band like Elio?

A health smart band continuously measures your physiological signals and turns them into useful indicators: sleep - recovery, stress, energy and performance. Elio belongs to this new generation of distraction-free sensors, like Whoop or Oura, but designed and hosted in Europe.

Unlike a classic smartwatch focused on notifications - Elio focuses on deep health: it analyses several physiological signals continuously (heart rate, heart rate variability, blood oxygen, skin temperature, motion) to understand how your body works and recovers.

The band is worn day and night, including during sport and sleep. Light, waterproof and long-lasting, it disappears on the wrist and works in the background. The Chutex app then delivers simple scores: recovery - sleep, stress, readiness.

Elio suits athletes (running, strength training - CrossFit - HYROX, endurance) as well as active people who want to sleep better, lower stress, lose weight or simply track their health proactively, without being experts.

Recovery and HRV: know every morning if you are ready

Heart rate variability (HRV) is the best consumer marker of nervous-system recovery. Elio measures it overnight and combines it with sleep and resting heart rate to compute a recovery score.

Each morning - Elio shows a readiness index: green when your body is ready for an intense session, orange or red when it is better to recover. It is the equivalent of Whoop's recovery score or Oura's readiness, but connected to the Aria AI coach.

Tracking your HRV helps avoid overtraining, optimise rest days and observe trends that may correlate with fatigue, stress or recovery dips. Training load is tracked in parallel to balance effort and recovery.

Over the weeks - Elio establishes your personal baseline. Any deviation (falling HRV, rising resting heart rate, degraded sleep) is detected and explained, jargon-free, so you can act at the right moment.

Sleep tracking: stages - quality and personalised advice

Sleep is the first lever of recovery, weight loss and performance. Each night Elio analyses duration, stages (light, deep - REM), sleep latency, respiratory rate and skin temperature.

Elio assigns a sleep score and explains what influenced it: bedtime - regularity, alcohol, late workouts, stress. The Aria coach suggests an optimal bedtime and routine tips to gain deep, restorative sleep.

Deep and REM sleep tracking helps you understand the next day's energy. Combined with nightly HRV, it gives a faithful picture of real recovery, far more precise than sleep duration alone.

For athletes and stressed people alike, better sleep changes everything: better recovery, better weight management, mood and focus. Elio turns invisible nights into clear, actionable data.

For suspected sleep apnea or severe insomnia, clinical sleep testing remains the reference. Elio does not diagnose sleep apnea.

Sport and performance: VO2max - effort zones and training load

Elio is built for people who train. It estimates VO2max, tracks heart-rate zones, calories, training load and the recovery time needed after each session.

Whether you run, cycle, swim, lift, do CrossFit or HYROX - Elio recognises the effort and measures its intensity. You know if a session was too hard, well-dosed, or whether you can add one.

VO2max estimation and resting heart-rate trends are long-term markers of your fitness progress. Elio tracks them and shows your trends week after week.

The band is worn on the wrist or upper arm and stays discreet during effort. The band syncs via Bluetooth to the Chutex app on your phone during sport and daily wear. Chutex Care is a teleassistance service available in France only.

Aria, the AI health coach included in the Chutex app

Raw data is useless without interpretation. Aria, the Chutex artificial intelligence, cross-references your metrics (sleep - HRV, activity, stress, weight) and turns them into personalised advice in plain language.

Each week Aria generates a health summary, spots trends and proposes concrete actions: adjust your training load, move bedtime earlier, add heart-coherence breathing on high-stress days.

Unlike many competitors who reserve their AI coach for a separate premium subscription - Aria is included with Elio (annual plan, no monthly fee). You can also share your data with your doctor, coach or a loved one, deciding who sees what.

The more you wear Elio, the more Aria learns your rhythms and refines its recommendations. It is continuous, proactive guidance that turns health tracking into real progress.

Weight loss: Elio band + Vita scale in one app

Weight management is more than a number on the scale. Elio and the Vita body composition scale share the same Chutex app to connect activity, sleep, stress and body composition.

The Vita scale measures weight but also fat mass, muscle mass, body water, visceral fat and metabolic index via bio-impedance. Combined with the calorie expenditure and sleep tracked by Elio, it gives a complete view of your metabolism.

Aria links these data: degraded sleep or high stress slowing weight loss, falling energy expenditure, rising muscle mass. You understand what works instead of chasing a fluctuating number.

This ecosystem (band, scale and AI coach in a single app) is what sets Elio apart from isolated trackers. With the Vita body composition scale in the same app, Elio can display an experimental metabolic trend indicator, not a glucometer, not for diabetes diagnosis or treatment, and not medical decision guidance.

European alternative to Whoop - Fitbit and Oura: data practices by market

Your health data is among the most sensitive there is. Your data is hosted in France by Free Pro, a hosting provider with HDS (Health Data Host) certification. Read the privacy policy applicable to your country.

Against US players like Whoop - Fitbit (Google) or Oura, whose data often transits outside Europe - Elio offers a GDPR-oriented alternative for users who care about data residency.

Elio is an annual plan ($264, no VAT): the band, the Chutex app, updates and the Aria AI coach for 12 months of Chutex Health services, with no monthly fee and no hidden cost. Where some competitors lock the device without a subscription - Chutex relies on a complete ecosystem and customer service in France.

Choosing Elio means combining wellness tracking (HRV, heart-rhythm trace on demand - SpO2, sleep - VO2max trends) with a European product; some services are available in France only unless explicitly stated for your country.
