How does the Oura Ring integrate with the Natural Cycles app for fertility tracking?

The Oura Ring integrates seamlessly with the Natural Cycles app to enhance fertility tracking by providing precise physiological data that is crucial for predicting fertile windows. As a wearable device, the Oura Ring continuously monitors the wearer's body temperature, one of the key indicators of fertility, along with heart rate and sleep patterns. This continuous temperature monitoring enables more accurate detection of the slight rise in basal body temperature that accompanies ovulation. The information gathered by the Oura Ring is then synced with the Natural Cycles app, which uses an algorithm to analyze the temperature data along with menstrual cycle information entered by the user. This integration results in a personalized and refined prediction of fertile days, thereby assisting individuals or couples in planning or preventing pregnancy with enhanced effectiveness.
