Ebb & Flow is a perimenopause and menopause tracker built for irregular cycles - predictions get honestly wider as your cycles get less regular, instead of fake-confident.

One-tap symptom logging (47 built-in symptoms). Cycle calendar with perimenopause-aware predictions. Pattern and trigger correlation insights from your own data. A one-page doctor-visit report (PDF or email) - top symptoms, frequency, timing - so appointments start from facts instead of vibes. Relief library with paced breathing, symptom heatmap, community.

Why I built it: every cycle app assumes a tidy 28-day cycle, and perimenopause laughs at that. The doctor-visit report is the feature I actually care about - you walk into a 10-minute appointment with data.

Free tier includes tracking, cycle calendar, community, and one doctor report per month. Plus is $7.99/mo or $4.99/mo billed yearly.

It's in beta and I'm at the "does anyone want this" stage - brutal feedback welcome. It organizes your observations; it is not medical advice or a diagnostic tool.
