Withings has unveiled a significant update to its ScanWatch 2 smartwatch at IFA 2025, focusing on enhanced health tracking and predictive AI capabilities. The new features are set to revolutionize the way users monitor their health.
The centerpiece of the upgrade is the new HealthSense 4 operating system, which incorporates advanced algorithms designed to monitor and analyze 35 different health metrics. A key feature of HealthSense 4 is its predictive AI, which provides users with alerts about potential health changes. These alerts can range from notifications about the start of a menstrual cycle to warnings about possible oncoming illness. This functionality places Withings in a competitive space with other wearables offering similar AI-driven health insights, such as Oura’s Symptom Radar.
Beyond software enhancements, the ScanWatch 2 boasts an improved battery life, now lasting up to 35 days on a single charge, an increase of approximately five days compared to its predecessor. The update also refines activity and sleep tracking. Updated algorithms are designed to provide more accurate step counts, and sleep tracking now offers detailed breakdowns of sleep stages and respiratory rhythms.
For Withings Plus members, a new Vitality Indicator aggregates various metrics, including heart rate variability, activity levels, body temperature, and blood oxygen saturation, to provide users with an estimate of their energy levels and fatigue. New color options – blue and silver – will be available exclusively on the 42mm model of the ScanWatch 2.
Withings is offering new users a one-month free trial of Withings Plus with the purchase of the ScanWatch 2. This trial grants access to an AI health assistant, the Vitality score, and Cardio Check-Up, a service that allows cardiologists to review the user’s heart health data. The updated ScanWatch 2 will be available for purchase starting September 5th, priced at $369.95.
