"Withings announced at IFA 2025 today that it's revamping the operating system of its ScanWatch 2 smartwatch. Called HealthSense 4, the update adds new algorithms for 35 health metrics as well as predictive AI-powered alerts when a user's health changes. The ScanWatch 2 also gains two new colors and improved battery life of 35 days - a roughly five-day increase from the original."
"In its press release, Withings says the updated algorithms improve activity tracking and step counts. Sleep tracking will also include more accurate breakdowns of sleep stages and respiratory rhythms. Withings Plus members also get a new Vitality Indicator, which adds up various metrics like heart rate variability, activity, body temperature, and blood oxygen saturation to estimate energy levels and fatigue."
"As for the predictive AI features, users will now get notifications ahead of health events like the beginning of a menstrual cycle or when they may be falling ill. This isn't particularly new for the industry, especially as AI-branded health features are now all the rage. Oura has a similar feature called Symptom Radar, while predictive illness warning features on wearables have been in the works ever since the start of the covid-19 pandemic."
