The Hormone Method is personalized hormonal wellness for women navigating cycles, perimenopause, hysterectomy, or menopause. It's built around your actual stage, not a one-size-fits-all program. The Hormone Method offers a 7-day free trial, then continues as an auto-renewing monthly subscription ($9.99/month). Your subscription unlocks daily check-ins for symptoms, energy, mood, sleep, and anxiety, plus guidance that shifts with where you really are — whether that's a cycle phase, surgical recovery, or life after menopause. You'll also get a personal AI coach available anytime, a full library covering nutrition, movement, breathwork, and mindfulness, and a history and patterns view that turns your daily logs into something useful for you and your next doctor's visit. There's also a section written specifically for your partner, so they understand what you're going through instead of guessing. Your data is never sold. That's structural, not just a policy. The Hormone Method is for educational purposes only and is not a substitute for professional medical advice. Always consult your healthcare provider before making health changes.
