Apple Watch Vitals can now predict someone is going to fall sick, days in advance

Apple Watch users are singing the praises of the new Vitals app, introduced in the watchOS 11 update, for its impressive ability to predict illness even before symptoms appear. Just a month after the update’s release, users are sharing stories of how the app flagged health anomalies, giving them a heads-up that they might be falling sick.

Recent posts on Reddit highlight the app’s accuracy. In one post, a user reported that the Vitals app had alerted them to potential health changes three days before they felt any symptoms. They mentioned feeling “off” in the morning, with symptoms creeping in by the evening.

Their post included a screenshot from the Vitals app, showing unusual spikes in wrist temperature in the days leading up to the illness.

Another Reddit user echoed this experience, calling the Vitals app “spot on” and praising it as a “super useful feature.” They also shared an image from their Apple Watch Ultra, showing temperature outliers recorded overnight, reinforcing the app’s predictive abilities.

The Vitals app works by monitoring various metrics during sleep, including heart rate, respiratory rate, blood oxygen levels, skin temperature, and sleep patterns.

When these data points stray significantly from the user’s usual range, they are marked as outliers, triggering a notification.

While the app doesn’t diagnose illnesses or instruct users to seek medical attention, it alerts them to these unusual patterns, encouraging them to be proactive about their health.

This predictive feature is quickly becoming a favourite among Apple Watch users, particularly for those using the latest models like the Apple Watch Ultra. It provides a deeper understanding of the body’s signals, helping users stay ahead of potential health issues.

As stories of its success spread, the Vitals app is shaping up to be one of the standout features of watchOS 11, adding even more value to Apple’s popular wearable.
