Optical heart rate sensor
Day and night the optical heart rate sensor keeps tabs on heart rate but conserves battery life by activating periodically around the clock. Continuous heart rate is activated and recorded when using workout mode.
Clinically validated Oxygen Saturation (SpO2)
To deliver the percentage of blood oxygen, or SpO2, ScanWatch uses a multi-wavelength PPG sensor to emit and measure red and infrared reflections of blood vessels in the wrist. Normal SpO2 values vary between 90 and 100%, and readings appear on the watch and in the app.
ECG readings
An ECG is the best way to detect atrial fibrillation (AFib), a highly prevalent heart arrhythmia. AFib often goes undiagnosed because it can show no symptoms and/or not be present during doctor’s visits because the episodes can be intermittent.
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.
Share with a doctor
All heart health data is compiled in the app and can be easily shared with a doctor, health coach, or loved one with a few taps via the Health Report feature.

In-depth analytics
Advanced Sleep Tracking
ScanWatch Horizon collects numerous data points to measure Sleep cycles, track breathing disturbances and then calculates your overall Sleep Score—automatically.

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 Health Mate app so you can view your trends.
