The Vitals app monitors several metrics of oversleeping, including heart and respiratory rates, blood oxygen levels, skin temperature, and sleep patterns.
Now, Apple Watch users are singing the praises of this new feature, an app called Vitals, in the watchOS 11 update. This feature is capable of predicting illness even before the symptoms have begun to manifest.
Just a month after its release, stories of how the app flags health anomalies have been shared, which gives the user a heads-up that he or she might be falling sick.
Recent posts on Reddit show that the app is relatively accurate. For instance, a user claimed Vitals picked up possible health changes three days before the symptoms began appearing.
They felt “off” in the morning and said full-blown symptoms had started by the evening.
Their post was supported by a screenshot from the Vitals app showing unusual spikes in wrist temperature in the days leading to the sickness.
Another user shared the same experience on Reddit: “It’s spot on, super useful feature,” they say.
They shared a photo taken with the Apple Watch Ultra where the temperature outliers recorded overnight would further support the predictions from the app.
The Vitals app tracks sleep and tracks all these metrics: heart rate, respiratory rate, blood oxygen levels, skin temperature, and sleep patterns.
Whenever these data points become remarkably off from the user’s norm, they are termed outliers, and a notice is triggered.
The application never diagnoses an illness or instructs its users to seek medical attention, but it alerts them to these patterns and advises them to take proactive healthcare.
