Introduction to Natural Cycles
Are you looking for a reliable, hormone-free birth control option? Natural Cycles is changing the way women approach contraception by combining advanced science with user-friendly technology. As the world’s first FDA-cleared birth control app, Natural Cycles offers a personalized, non-invasive solution for those who want to take control of their fertility—naturally.

How Does Natural Cycles Work?
Natural Cycles uses a unique algorithm to analyze your daily basal body temperature and menstrual cycle data. Here’s how it works:
- Daily Temperature Tracking:
Each morning, you take your temperature with a basal thermometer or compatible wearable device. - Data Entry:
Enter your temperature and any other relevant symptoms into the app. - Fertility Prediction:
The app uses your data to predict fertile and non-fertile days, helping you avoid or plan pregnancy.
Why Temperature Matters
Your basal body temperature slightly increases after ovulation. By tracking these changes, Natural Cycles can accurately pinpoint your fertile window.
