Trust in science to support you

• NC° partner view lets you choose to allow your partner to follow your pregnancy planning journey.
Monitor your pregnancy
• NC° Follow Pregnancy starts when you log a positive pregnancy test, and monitors your baby’s developmental stages.
• Get tailored pregnancy guidance, with trackers for morning sickness and other symptoms.
• Track the exact date of ovulation that you conceived to add your predicted due date to the calendar.
Get postpartum support
• NC° Postpartum supports you after pregnancy with daily check-ins and articles with expert guidance.
• Understand your body as it changes with trackers for mood, symptoms and post-partum bleeding.

More than a period tracker
• The NC° app adapts to your unique cycle, tracking even irregular periods and ovulation days on a calendar.
• Most period trackers assume you have a 28-day cycle, when most women don’t. Our tracker gives you tailor-made guidance based on your menstrual cycle.

• Receive an NC° Band with an NC° Annual subscription.
Subscription service
• Subscribe to our monthly or annual plan to unlock core features and personalised fertility guidance.
Every Natural Cycles subscription includes our advanced data protection program. Some free period tracking apps don’t have the same level of accountability. Your privacy is a priority. Natural Cycles is designed to keep your data safe.
The NC° app is more than just a period tracker, it’s a medical device. Join 6 Million+ women who use our ovulation tracker and daily fertility updates to prevent pregnancy, plan pregnancy and more.
Natural Cycles connects with Apple Health to read and write your health data, including medications, body temperature and cycle information.
