Why it matters

In most cases, a lower heart rate is the result of better cardiovascular fitness. Track the evolution of your heart rate over time and use it to improve overall health.

What’s behind the tech

Steel HR collects data on heart rate using photoplethysmography (PPG). Unlike other trackers, the HR sensor is protected by a scratch-proof sapphire glass to ensure accurate measurements over the long term. In order to optimize energy consumption, Steel HR will monitor heart rate at a varying frequency, according to your real-time activity.

Daily activity tracking

Steel HR automatically counts steps and recognizes walking, running, swimming or sleeping. Steel HR is water-resistant to 50m.

Why it matters

Setting a step goal is generally associated with an increase of physical activity which can help you hit your target weight, strengthen your heart, and get a better night’s sleep.

What’s behind the tech

To guarantee the viability of the data in all situations, our proprietary step tracking algorithm has been calibrated using a large set of diverse people moving on various terrains to account for different walking styles.

Automatic sleep monitoring

If you wear Steel HR to bed it will automatically track light and deep sleep cycles, duration, and sleep quality via the Sleep Score. Plus, the Smart Wake-up feature can get you out of bed at the best time according to your sleep cycle.

Why it matters

Sleep tracking helps you understand your night and make choices that can improve them.

What’s behind the tech

The accelerometer, paired with heart rate, allows a comprehensive and detailed analysis of your night. Our proprietary AI has been calibrated with a sleep laboratory in Manheim, Germany and with Beclere Hospital in France, using polysomnography, considered to be the gold standard for sleep analysis.

Fitness Level assessment

Steel HR Sport can assess your Fitness Level when you run or walk based on the maximal oxygen consumption (VO2 Max) estimation.

A key indicator of fitness

VO2 max is defined as the maximum amount of oxygen an individual consumes over one minute during intense physical effort. The more oxygen consumed, the harder muscles can work, and therefore the higher the VO2 max level.

What’s behind the tech

The algorithm to calculate VO2 max has been developed by Firstbeat, a company which is the reference on the market. It is proven to be 95% accurate compared to laboratory measurements.

Record battery life

With a rechargeable battery life of up to 25 days, you can spend more time moving and less time charging.

Smart
notifications

You can stay in-the-know on the go with a vibration and smartphone notifications right on the embedded digital screen. Steel HR supports calls, texts, events and all the apps you choose.

Data at your fingertips

Steel HR seamlessly syncs with the free Withings app. You can access your data in the app or on the web with your personal Withings account. See your progress, share your data, and more.
