Women Can Now Track Their Fertility with Apple Watch

Knowing when to get pregnant may be one of the most important pieces of personal health information. Yet, a recent study conducted on 3,000 men and women across the US, UK and Sweden, reveals that less than 30% are aware of how the female body works.(1) Natural Cycles, the clinically-tested fertility app, aims to change that and announced the launch of their Apple Watch app. Women will now be able to access the key features of the Natural Cycles app on their Apple Watch, such as seeing their current fertility status (red and green circles), receiving personalized messages and even add today's data using the digital crown.

"One's fertility is something really intimate. We are humbled and proud that Natural Cycles is the preferred fertility monitor of so many women across the globe. With Apple Watch we have the missing piece of the puzzle, bringing our app closer to women, making it a natural part of her everyday routine and ensuring that she is always informed about her fertility status," says Natural Cycles’ CTO & co-founder Elina Berglund Scherwitzl.

This is how Natural Cycles works: a woman wakes up in the morning, measures her temperature in her mouth and enters it into the app. A proprietary algorithm analyzes the data and returns to the user a red or a green day depending on whether she is fertile. A green day is to 99.9% not fertile according to clinical studies.(2) During red days, the woman may be fertile. A year after launching the app, Natural Cycles already has 100,000 users, also called Cyclers, in 90 countries, with the majority living in the Nordics, Brazil, US and Germany. On average, Cyclers use the app five out of seven days per week and it appeals to women who want to take control over their fertility by understanding how their unique cycles work.

"This is probably one of the smartest decisions I’ve made in my life! I’m now starting my sixth month with Natural Cycles. I take my temperature every morning and add the data to the app. I'm so happy with it, and I love how it natural is! I actually look forward to the personal in-app messages. They're full of information and always put a smile on my face’, says My Annika, a 29-year-old Cycler from Sweden. Julia, a 22 year old Cycler from California writes: ‘I’m using Natural Cycles to avoid getting pregnant. In the future, I'll switch to plan a pregnancy. After 3 months, I’ve already learned so much about my body!"

Natural Cycles is available to download from the App Store, requires iOS 6.0 or later and is compatible with iPhone, iPad, iPod touch, and now Apple Watch.

About Natural Cycles
Natural Cycles was founded by husband and wife, Elina Berglund and Raoul Scherwitzl. With PhD’s in physics, they applied their mathematical techniques to developing the Natural Cycles algorithm. Elina was a researcher at CERN and was one of the physicists that discovered the Higgs Boson, which lead to the Nobel Prize in 2013. The Natural Cycles app was launched in August 2014 with a mission to educate and empower women to take control of their fertility and future around a vision where every pregnancy is wanted. Beyond the app offerings, the company advances scientific research in the field of contraception.
