Track perimenopause and menopause symptoms, HRT doses, and cycle changes in one place — then generate a doctor-ready PDF report before every appointment.

TRACK - Hot flashes, night sweats, mood, sleep quality, brain fog (0-5 severity) - HRT and supplement doses, with type and amount - Period and spotting days through the perimenopause transition UNDERSTAND - 14-day trend charts per symptom - Automatic "most frequent symptom" summary SHARE - One-tap PDF health report - symptom averages, peak severity, cycle days, and full medication log for the last 30 days PRIVATE BY DESIGN Your data stays on your device unless you choose to export or share it. HormoneSync+ unlocks unlimited history, Apple Health sync, and unlimited PDF reports.
