Garmin announced today it has partnered with fertility/birth control app Natural Cycles to share temperature data from the Garmin app to Natural Cycles. To use this feature, you’ll need a supported Garmin watch. Currently, these include the Fenix 8, Forerunner 570 and 970, Venu 3 and 3S, Venu 4, and Venu X1. (The full list of compatible devices is here.)

Those are all pricey watches—the Venu 3S is the cheapest among them, and will still run you $350—so I don’t expect anyone will rush out and get a Garmin just for the Natural Cycles integration. That said, Garmin is offering a discount to Natural Cycles subscribers, though the amount of the discount hasn’t been announced. Natural Cycles says it will send a discount link to new subscribers, and existing subscribers can access it through the “Buy Extra Supplies” page of the Natural Cycles app. 

What is Natural Cycles?

Natural Cycles is a fertility and birth control app for people who ovulate that tracks which days you’re most likely to be fertile. Body temperature tends to rise slightly with ovulation, so over the years, Natural Cycles has evolved from an app that asks you to use a thermometer to measure your temperature, to one that links to temperature-tracking wearables. The Oura Ring already has a Natural Cycles partnership (there are temperature sensors on the ring) and Natural Cycles launched their own specialized band for nighttime temperature tracking earlier this year. 

The price of a Natural Cycles subscription is frustratingly difficult to find on their website (I had to fill out a lengthy questionnaire and sit through several ads before being told I need to enter my email to get a price quote) but Apple’s App Store page for the Natural Cycles app lists in-app purchases as $28.49 monthly and $194.99 annually.
