TL;DR · WeSearch summary

The data is sent to a companion app on a paired iPhone. While existing smart rings rely purely on biophysical data extracted from sensors like those embedded into the Apple Watch, this ring also tracks chemical biomarkers by analysing sweat … Today’s smart rings work in exactly the same way as the Apple Watch, using exactly the same sensors. These enable the collection of an impressive range of data, including resting heart rate, heart rate variability, respiratory rate, temperature, cardiovascular age, activity, sleep cycles, and more.
