This is a look back at news from the week of . We wrote it on November 11, 2026, from the sources listed at the end.
Whoop partnered with Natural Cycles, a fertility tracking app, in early August 2026. The app can now calculate a user's daily fertility status automatically from skin temperature recorded overnight by the Whoop 5.0 and Whoop MG, Wareable reported.
How it works
Body temperature shifts slightly across the menstrual cycle. Natural Cycles uses that pattern to estimate fertile days. Traditionally the user takes a reading with a thermometer each morning. A wearable that records temperature all night removes that step.
Why it mattered
Natural Cycles is cleared by the FDA as a form of birth control. Connecting it to a general fitness band is another case of a consumer wearable supplying data to a regulated product.
The accuracy of the result depends on wearing the device every night.
