FDA-cleared contraception platform Natural Cycles can now be integrated with the Apple Watch.

The contraception brand analyzes a user’s every day body temperature to find out their fertility status. Now, as an alternative of taking their temperature orally, users can depend on their Apple Watch. Apple added temperature sensors to its watch last September.

“The primary yr starting Natural Cycles, many individuals including myself said, ‘Oh, if only the Apple Watch would add a temperature sensor,’ then we wouldn’t should measure of their mouth,” said Natural Cycles cofounder and chief executive officer Elina Berglund.

In line with Berglund, when Apple announced it might add the temperature sensor to its watch, requests from Natural Cycles users flooded in.

“This became our number-one request from our users, so we began collecting data and performing clinical studies to validate it, submitted it to the FDA which they cleared a few weeks ago,” she told WWD.

In the course of the clinical evaluation, Natural Cycles, which received $7 million in funding from Samsung Ventures in February, analyzed 272 women and 505 complete menstrual cycles. As with an oral thermometer and the Oura Ring, Natural Cycles found when using the Apple Watch it was 93 percent effective at stopping pregnancy with “typical use” and 98 percent effective with “perfect use.”

When wearing an Apple Watch and using Natural Cycles, a user will allow Apple Health to trace temperature which may then be synced up with the Natural Cycles app, making the method more convenient.

“What really changes is the benefit of use,” Berglund said. “It’s just easier to sleep with it than to recollect to do something first within the morning while you get up.”

Before integrating with Apple, Natural Cycles also partnered with Oura. Through that integration, temperatures are recorded via the Oura Ring. In line with Berglund, the quantity of days that the temperature is tracked is outnumbered by those using the Oura Ring versus those taking their very own temperature. While that is the case, Berglund doesn’t think using thermometers will ever go away for the brand.

“Women are different they usually wish to have options, what suits them, so I do think that we’ll all the time have women using the thermometer,” she said.

With the success of the Oura partnership and the requests for the Apple integration, Berglund expects wearables to proceed to drive the business and maybe assist in acquiring latest customers who haven’t tried the brand because they don’t wish to take their temperature every day.

“We expect it to be big and we expect demand to be very high because we just see how often we get this request, that users wish to use Natural Cycles with their Apple Watch because we all know so many ladies on the market have an Apple Watch already, including a lot of our existing users today,” she said.

The brand, which nearly doubled subscription sales (subscriptions are $99 annually) between August 2022 and August 2023, plans to partner with additional wearable brands in the long run.

“It looks like an increasing number of wearables are adding temperature sensor capabilities, which is great for us,” Berglund said. “We wish to supply integration with the largest players on the market.”
