Natural Cycles, the company behind a controversial FDA-cleared birth control app, is replacing its thermometer with a wristband that measures skin temperature, heart rate, and movement during sleep. The newly-launched wristband costs $129.99 and syncs with the Natural Cycles app, which uses an algorithm to determine a person’s “daily fertility status.”
