Belle Health (Belle App) is on a mission to close the women’s health gap by improving recognition, care, and daily management of cyclical disorders such as Premenstrual Dysphoric Disorder (PMDD). The company builds evidence-informed digital tools that help people understand their symptoms, access practical coping strategies, and communicate medical information clearly to clinicians.

Belle provides a clinically‑backed mobile app and product ecosystem that combines customizable PMDD symptom tracking, medically-endorsed reports for healthcare providers, and evidence-based CBT techniques and exercises to reduce symptom burden. The platform emphasises data privacy and security (GDPR-compliant, two-factor authentication), uses consented user data to support female health research, and fosters community involvement through a public roadmap, courses, and support resources.
