ECG
ECG measurement and AFib detection*
Atrial fibrillation, or AFib, is the most common cardiac arrhythmia, an anomaly of the heart’s electrical activity. It is caused by a disorganized firing of electrical impulses in the right atrium near the sinoatrial node, the natural pacemaker of the heart. Learn more
Atrial fibrillation (AFib) is thought to be responsible for approximately 30% of strokes. 90% of these events could be prevented if diagnosed earlier. ScanWatch 2 can record a clinically validated electrocardiogram and detect signs of atrial fibrillation—a form of arrhythmia that can be damaging to your health if left undiagnosed. ECG readings can be easily shared with your doctor via the Withings app, providing valuable information to help them track your heart health. Follow the best practices guide.**
When you receive a notification, the app will encourage you to record an ECG. The ECG may not necessarily be classifiable (if your heart rate is high or low), but the results of the ECG may help your doctor diagnose atrial fibrillation. You can view and share your results at any time within the Withings app.
High & low resting heart rate
Heart rate and rhythm are measured by the exclusive PPG multi-wavelength sensor, which uses light absorbed by the blood and skin to measure blood flow change in your wrist’s microvascular beds, made up of arterioles, capillaries, and venules. Learn more
By default, ScanWatch 2 triggers a measurement from time to time when you are stationary or walking. Note that your heart rate data is regularly transferred to the Withings app where you can see results. Learn more
If you have been inactive for at least 10 minutes (also known as a rest period) and ScanWatch 2vdetects a heart rate that is high compared to your usual heart rate, you will receive a notification. Similarly, if your heart rate falls below a certain value of beats per minute, ScanWatch 2 will send you a notification. Please note that any slight movement (such as reaching for an object) can 'reset' this rest period. The normal heart rate is between 50 and 100 bpm, but these figures may vary depending on the person. That’s why we make it easy for you to change the high and low heart rate thresholds in the Withings app. You can also turn this feature on and off at any time.
* Note: Feature availability varies depending on location*
* Available via Withings ECG App
Temperature
With ScanWatch 2, optimizing your physical performance is made easier via the workout zones feature. You’ll get key insights into your body temperature as it changes*. The three temperature zones have been carefully designated so you can understand and use them to support your well-being:
Warm Up Zone: This is the lowest temperature zone, that’s optimal for preparing your body before starting your workout. Spending the first few minutes in this zone helps to raise your body temperature gradually, priming your muscles for optimal performance.
Performance Zone: This zone is where you should stay for the majority of your workout. It provides ideal conditions for peak muscle performance, allowing you to workout efficiently and achieve better overall results.
Overheating Zone: This zone should be avoided whenever possible. Exercising in this zone can have negative consequences related to overheating — muscle cramps, nausea, headaches, dizziness, confusion, or even loss of consciousness. Ensuring you stay clear of this zone is essential for your well-being while you workout.
If your body temperature reaches the overheating zone, you should immediately slow down your physical activity and allow your body temperature to return to a lower zone, ideally the performance zone or a normal body temperature for you.
Disclaimer: In case of a fever, body temperature values will be inaccurate.
*You can find your body temperature variation data in the 'Daily Steps' view on your app.
SpO2
SpO2 stands for peripheral capillary oxygen saturation, an estimate of the amount of oxygen in the blood. More specifically, it is the percentage of oxygenated hemoglobin compared to the total amount of hemoglobin in the blood.
It is often considered to be the fifth vital sign, along with pulse, respiratory rate, blood pressure, and body temperature. Hemoglobin is a protein that carries oxygen in the blood to your organs. It is found inside red blood cells and gives them their red color. Once oxygen is in our organs, it acts as the fuel that allows our cells to work.
Women Health
Track your menstrual cycle over the long-term
Period irregularities and changes are very common. Tracking your symptoms, phases, and the length of your menstrual cycle month after month can help you understand your unique cycle patterns. Get notifications and be empowered by comprehensive data that allows you to make informed decisions regarding your menstrual health and build balanced routines.
Compare with other in-app data to help assess your overall health
It’s important to monitor your period because significant changes may be linked to other health issues. Comparing your menstrual cycle data with your other metrics like heart rate, respiratory rate or sleep quality can help you recognize connections between your reproductive health and the rest of your body’s systems.
Get a comprehensive health report to share with your doctor
Export all of your menstrual health data, including symptoms, duration, and phases, in a comprehensive PDF report that can be sent directly to your doctor. This report provides a holistic view of your data and can lead to a more accurate assessment of your cycle patterns. This may also facilitate earlier identification of signs related to developing health issues.
24/7 Tracking
Sleep tracking helps you understand your nights and make choices that can improve them. 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.
Sleep Cycles
ScanWatch 2 tracks your sleep cycles (light and deep), sleep duration, interruptions, and time taken to fall asleep and wake up. All data is logged in the Withings app so you can view and analyze your trends over time.
Sleep Score
Our exclusive algorithm automatically scores your night based on sleep cycles, duration, regularity and interruptions.
Overnight breathing disturbances
In addition to analyzing sleep, activating the Respiratory Scan can identify breathing disturbances, and provide an analysis of continuous blood oxygen levels (SpO2), heart rate, motion and breathing rate.
Sleep heart rate
Punctual measurements of your heart rate at night will help you understand your sleep heart rate, the average heart rate during sleep. It differs from resting heart rate which is a single measurement, usually taken just after waking up.
Smart Wake-Up
Because ScanWatch 2 knows if you are in a light or deep stage, it can choose the best time to wake you up according to your schedule. You simply set a wake-up time in the app, and ScanWatch 2 will wake you with a light vibration.
Timeless design & Clinically developed
With premium build quality and customizable features, ScanWatch 2 adapts to your style and mood while maintaining a lightweight, elegant design.
Phenomenal 35-day battery life
Experience freedom with ScanWatch 2 and its remarkable battery life. Say goodbye to daily charging—its long-lasting power ensures peace of mind and uninterrupted use. You’ll enjoy it so much you might forget it ever needs recharging.
