The Galaxy Watch 5 and 5 Pro already released the temperature tracking feature, but the accuracy of the body temperature is yet to be seen. Apple, however, is so confident in the accuracy of its temperature tracking that it has added estimated ovulation dates based on the shifts of the wearer’s basal body temperature. Nightly shifts in the body’s baseline temperature can help with more than sleep tracking, which the Apple Watch 8 also does. It can give people a visual on their watch’s screen of when they likely ovulated, as well as cycle deviation, all complete with notifications so you can stay on top of their fertility tracking. The Apple Watch Series 8 has two temperature sensors, one on the back of the watch and the other behind the display; to accurately discern changes in body temperature versus changes in ambient temperature readings. For women’s health and people trying to conceive in general, this new feature in cycle tracking is an advanced resource for their reproductive health.
