Withings Revamps Smartwatch with New OS and Enhanced Features
Withings has unveiled a revamped version of its ScanWatch 2 smartwatch at IFA 2025, introducing a new operating system called HealthSense 4. This update incorporates algorithms for 35 health metrics and offers predictive AI-powered alerts for health changes. The ScanWatch 2 boasts a battery life of 35 days, an improvement of five days over its predecessor, reports 24brussels.
The updated algorithms significantly enhance activity tracking, including step counts. Sleep tracking now features more precise breakdowns of sleep stages and respiratory rhythms. Additionally, Withings Plus members will benefit from a newly introduced Vitality Indicator, which aggregates various metrics—such as heart rate variability, activity levels, body temperature, and blood oxygen saturation—to assess energy levels and fatigue.
The smartwatch’s predictive capabilities include notifications for health events like the onset of a menstrual cycle or potential illness. While such features are increasingly common in the industry, Withings stands out as a smaller entity that has typically focused on lifestyle-oriented smartwatches with science-backed functionalities. The company aims to gain traction despite facing challenges in securing FDA approval for some advanced health features.
The new colors for the ScanWatch 2—blue and silver—will be available exclusively in the larger 42mm model. First-time buyers will receive a one-month free trial of Withings Plus, which provides access to an AI health assistant, the Vitality score, and the Cardio Check-Up feature, previously launched this year for cardiologist review of heart health data. The watches begin sales today, priced at $369.95.
