Apple Watch users have been surprised by the new Vitals app, which reportedly alerts them when they’re getting sick before they even feel symptoms. The app tracks key health metrics like heart rate, respiratory rate, blood oxygen, wrist temperature, and sleep duration. After a watchOS 11 update, users started noticing the app’s ability to detect potential illness by identifying outliers in metrics such as wrist temperature. One user shared on Reddit how the app warned them of illness days before they started feeling unwell, sparking discussions about how useful the feature could be.
Several users commented on similar experiences, with some claiming their Apple Watch detected they were sick before any symptoms appeared. Although the feature has been praised for its accuracy, users are reminded not to rely solely on it for diagnosing medical conditions. Interestingly, the app’s blood oxygen measurement feature remains banned in the U.S. due to a legal dispute over patent infringement, but the app’s other capabilities continue to impress its users.
This new feature has brought attention to how technology is evolving to track and predict personal health, especially during cold and flu season. However, the app is a tool meant to complement, not replace, professional medical advice.
