Many people who menstruate lack a reliable, science‑backed tool to consistently log cycle data, receive personalized health insights, and safely share information with partners or clinicians. Existing solutions often provide limited predictions, inadequate privacy safeguards, and do not contribute data to improve research on under‑studied female health conditions.
Clue offers a mobile‑first platform that records menstrual, ovulatory, and reproductive health metrics across iOS, Android, and watchOS devices. The app applies data‑driven algorithms to generate cycle forecasts, symptom trends, and fertility windows tailored to each user’s history. Users can switch between dedicated tracking modes for trying to conceive, pregnancy, and perimenopause, ensuring relevance throughout life stages. A premium subscription, Clue Plus, unlocks deeper pattern analysis, expert‑curated content, and the ability to share selected data with partners via Clue Connect. All data are anonymized and aggregated to support research collaborations with academic institutions, while strict GDPR‑compliant safeguards protect user privacy.
The primary users are individuals who menstruate and seek accurate, personalized cycle tracking—including those trying to conceive, pregnant, or navigating perimenopause—as well as clinicians who benefit from aggregated health insights.
