ScanWatch is a hybrid smartwatch designed to monitor health parameters, detect AFib, and help improve overall fitness.

Developed with professionals from world-renowned institutions, ScanWatch boasts clinically validated ECG capabilities, an oximeter for SpO2 measures, and an exceptional battery life of up to 30 days.

The appeal should be obvious to anyone who appreciates the classic design and wants to stay on top of their heart and sleep health.


Not many true smartwatches or fitness trackers contain quite as many health-monitoring features, from general activity to comprehensive sleep tracking.


Withings has got a lot right with the ScanWatch. It is an attractive hybrid watch that blends traditional aesthetics with some of the smartest technology available on any wearable today (smartwatches included).


More than ever, we need to take responsibility for our own health and the technology ScanWatch provides allows us to do that.

ScanWatch tracks heart rate every second during workouts to optimize training, and monitors daily and overnight heart rate to help improve health over time.

ScanWatch 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.

Note: ECG must be used under the care of a physician. ECG requires a free in-app activation process. ECG is not intended for use by people under 22 years old. Prescription Use Only.

How to record an ECG

To record an ECG, sit and rest, press the digital crown, scroll in the menu to find the ECG option, press again, then place your fingers on the front electrode for 30 seconds.

Withings app | Withings
Withings App | Withings

Your smartphone can display the live signal during the record, and will keep all measurements to view and share at any time.

How it works

ScanWatch is equipped with three electrodes: two are on the back of the case and the other is the metal ring around the watchface.

When you place your finger on the ring, it closes a loop that allows the watch to measure your heart's electrical activity. This method is called a one-lead electrocardiogram.

Why it matters

An ECG is a way to detect atrial fibrillation (AFib), a prevalent heart arrhythmia. It can be a serious condition that can go undiagnosed because it can show no symptoms and/or not be present during doctor’s visits because the episodes can be intermittent.

Sleep analysis

Lie down, breathe, dream.

ScanWatch computes numerous data points to measure sleep cycles, monitor breathing disturbances and then calculates your overall Sleep Score—automatically.

Scanwatch | Withings

Sleep tracking helps you understand your night and make choices that can improve them, such as changing daily activity. 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 tracks your sleep cycles (light and deep), duration of sleep, time to be asleep and wake up as well as interruptions, and logs it in the Withings app so you can view your trends to help manage your sleep quality.

Sleep Score

Overnight breathing disturbances

In addition to analyzing sleep, activating the Respiratory Wellness Scan can monitor breathing disturbances via the PPG sensor, and the accelerometer.

Sleep heart rate

Periodic 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 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 will wake you with a light vibration.

Fitness level

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.
