Z Apple Watch se is becoming an increasingly interesting health monitoring device. New research conducted by experts from the University of Waterloo in Canada has revealed, for example, that these watches are even able to measure the user's stress level, and are also very good at predicting it. So we could expect these watches to become very sophisticated in the future.

Specifically, the scientists managed to find out that from the ECG measured by the watch, using specially created algorithms, it is possible to predict with a very decent accuracy how much stress the user will experience in the near future, which could control him in a certain way. The accuracy of forecasts, which can help in better coping with stress thanks to the possibility of preparing for its onslaught, also increases with the addition of additional data, such as sleep measurements and the like. However, in order for everything to work as well as possible, it is necessary to develop algorithms that are able to predict the level of stress from the data as accurately as possible, which will still take some time. However, just the fact that the current hardware Apple Watch stress monitoring enables them to hold great promise for the future.
Garmins too, although from something else and differently.
I have the opportunity to compare garmin and aw with the Athlytic app and the results are almost the same.
So they are not :D
… Garmins are much more accurate!
