HerFlow — Perimenopause Copilot:  A

HerFlow — Perimenopause Copilot:  A patient-owned web app that helps women in perimenopause track symptoms, spot real patterns, and walk into doctor visits with clear, honest data.

The problem: Perimenopause can last for years and bring dozens of shifting symptoms like sleep loss, hot flashes, mood swings and brain fog. Women often feel dismissed at appointments because they can't show what has been happening over time. Most trackers focus only on periods.

The solution: HerFlow tracks the whole transition. A 30-second daily check-in turns into trends, symptom clusters and evidence on whether treatments work. It also produces doctor-ready reports and visit briefs. The data belongs to the patient.
