Key insight: Generic period apps are essentially just calendars — the real value is in predicting *your* unique symptom cascade so you can negotiate your life around biology instead of being surprised by it.

The Problem

Most period tracking apps use generic cycle data and can't predict *when* specific symptoms (migraines, fatigue, bloating) will hit for individual users. Women waste time managing symptoms reactively instead of proactively scheduling life around their actual cycle patterns.

Target Audience

Women aged 18-45 with irregular or symptom-heavy cycles, especially athletes, executives, and people with chronic migraine who need predictability for performance and health management.

Why Now?

Cursor/Lovable can scaffold ML symptom classification in days; menstrual health is trending (Roe v. Wade aftereffect, athlete optimization focus); personalized health AI is expected by 2025.

What's Missing

Existing apps treat all cycles as standard 28 days; they don't use individual historical data to predict *personalized* symptom windows. This requires backend ML which VC-funded apps avoid (cost/complexity).
