In the next firmware update for ScanWatch 2 coming this September, 2025, we will be launching HealthSense 4, a brand new operating system. This OS introduces advanced algorithms that monitor 35 health parameters with unmatched precision, delivering timely alerts to support energy levels and reduce fatigue. 

Specifically, the new algorithms in ScanWatch 2 offer advanced sleep and energy monitoring, providing highly precise tracking of sleep architecture, now including REM sleep, which is essential for memory, brain plasticity, and emotional regulation. It also includes accurate measurement of nocturnal respiratory rhythm for deeper health insights.

Note: Most of these updates will be fully activated with the next Withings App update, but you will be able to take advantage of new breathing exercises as soon as the firmware is updated.

Additionally, we will be launching the new Vitality Indicator, which combines data from heart rate variability, physical activity, body temperature, oxygen saturation, respiratory rhythm, and sleep quality to analyze energy levels and pinpoint fatigue causes. It sends personalized notifications to help users target and improve the factors that most impact their well-being.

 

Finally, we are announcing a new "Midnight Blue" color for our current ScanWatch 2 line, available for purchase exclusively on Withings.com as of September 5th, 2025, and at retail worldwide starting October 6.
