Unlock a whole new way to use Natural Cycles, with our latest app experience: NC° Perimenopause, helping you decode hormonal shifts and navigate the next stage of the journey with confidence. Read on to learn how NC° Perimenopause supports users in the lead-up to menopause, the latest features available, and how to access this new mode in the app.

Our mission at Natural Cycles has always been to empower women with knowledge about their health. There is a wealth of misinformation around perimenopause, and this pivotal life phase remains a mystery to many of us, even as we travel through it. NC° Perimenopause aims to change that, offering you a new way to navigate the changes happening in your body.

Understand what stage you may be in

This newest app experience uses the first-of-its-kind NC° Menopause Algorithm to estimate if you’re in early, mid, or late perimenopause. These stages tend to be associated with different hormonal patterns that can happen in the lead-up to menopause, when periods stop entirely.

The NC° Perimenopause Assessment analyzes your symptoms, looks at cycle changes, and considers factors such as age when determining perimenopausal stages. This assessment is a useful tool that helps facilitate informed discussions with your healthcare provider.

Your symptoms make sense here

Fatigue. Night sweats. Brain fog. These are some of the most common symptoms of perimenopause, but they are not always the first signs. There are so many symptoms associated with perimenopause, from hair loss to joint pain to insomnia — everyone’s experience is different.

A large part of decoding hormonal shifts is understanding our own relationships with our symptoms. NC° Perimenopause includes extensive tracking and even lets you input potential triggers, such as caffeine and alcohol, so the app can help you see how your lifestyle and symptoms may affect one another. In addition, the app analyzes key biometrics to help you see the bigger picture.

Symptoms, treatment options, and fertility goals look different for everyone, and NC° Perimenopause is built to reflect this. Even within this app mode, you can customize your journey in several ways. For example, you can use the app to track alongside hormone therapy, or as a tool to prevent pregnancy.

Backed by clinical research and leading menopause experts

NC° Perimenopause is packed full of informational content, informed by the latest research, and reviewed by healthcare professionals in this space. We worked with experts from our own Medical Advisory Board, including Dr. Barbara Levy, to create an experience that supports your journey with science-backed data.

In addition to extensive symptom tracking, you’ll be able to view any atypical cycle changes as they are flagged in the app. All this is neatly summarised in your bespoke Cycle Report for easy sharing with your healthcare provider. Whether you use these insights to start building a care plan that fits you, or to monitor emerging patterns in your cycle, NC° Perimenopause puts you in control.
