Lunaception
Regulate your cycle naturally
Free · Designed for iPad
Track your menstrual cycle using the Lunaception method - a natural approach to cycle regulation through controlled light exposure. Privacy-first, no data tracking.
Discover Natural Cycle Regulation with Lunaception
Lunaception helps you regulate your menstrual cycle naturally using the scientifically-backed Lunaception method developed by Louise Lacey in 1975. By controlling your light exposure during sleep, you can work toward a more regular cycle without hormones or medications.
How It Works
The Lunaception method is simple: sleep in complete darkness most nights, and use a dim nightlight during your ovulation window (days 14-16 of your cycle). This mimics the natural light patterns humans experienced before artificial lighting, potentially helping to restore hormonal balance and cycle regularity.

The Science
Before electric lighting, women living together often experienced synchronized menstrual cycles that aligned with the moon's phases. Research suggests that light exposure plays a crucial role in regulating reproductive hormones. The Lunaception method recreates the light conditions that may have caused this natural synchronization.
Getting Started
Simply input your last period start date and cycle length during setup, and Lunaception will guide you through the daily light protocol. Track your adherence and watch as your cycle becomes more regular over time.
Note: Lunaception is not a form of birth control and should not be used to prevent pregnancy. Always consult your healthcare provider before making changes to your cycle management approach.
