The ECG feature alongside other measurements in the [Apple Watch](https://appleinsider.com/inside/Apple-Watch) can act a basic stress detector, claims a new study.

Back in 2020, the then forthcoming [Apple Watch Series 6](https://appleinsider.com/inside/Apple-Watch-Series-6) was rumored to include features for monitoring [mental health issues](https://appleinsider.com/articles/20/05/01/apple-watch-series-6-may-add-anxiety-monitoring-and-sleep-tracking), most specifically including anxiety. Apple has not included such an anxiety or stress app as yet.However, a limited new study claims that the Apple Watch is already useful for predicting stress, because of what else it is intended to detect.
