The Apple Watch Series 8 continues Apple’s health-tracking legacy and offers standard features. A heart rate sensor, SpO2 monitor, and electrocardiogram ECG are available to monitor heart and blood health.
Aside from this, there are some fascinating new developments, the most notable of which is a skin temperature sensor that enables more precise menstrual cycle monitoring.
Unlike the sensor on the Galaxy Watch 5, Apple’s sensor works right away. It detects irregularities in a wearer’s basal temperature while sleeping. This includes temperature fluctuations after ovulation, which results in more reliable fertility statistics.
Using this temperature-tracking approach, Apple also enhanced its sleep monitoring technology. Series 8 now indicates the amount of time spent in each sleep zone, including REM and deep sleep, and records these changes over time, thanks to watchOS 9.
What colors will Apple Watch 8 come in?
Stainless Steel Apple Watch Series 8 The stainless steel Apple Watch Series 8 is expected to be available in the same three color options as the Series 7: gold, silver, and graphite – the same variety of stainless steel finishes that Apple has already provided for two straight Apple Watch generations.
