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.
