PCOS symptom quiz.
One question per screen, about 3 minutes. Ends in a profile of where your symptoms cluster and which chapters cover them.
Start the quiz →Cycle & ovulation calculator.
Estimate your current phase, fertile window and next period from three inputs — with honest notes on why PCOS makes estimates fuzzy.
Open the calculator →Insulin-resistance risk checker.
A screening approximation from waist, BMI and history questions — the mechanism behind many PCOS symptoms, explained as you go.
Check your risk →BMI calculator, with PCOS context.
The most-used reference metric, and the most misunderstood — with interpretation written for PCOS, not for everyone.
Calculate BMI →Tools are a guide. The Companion is the plan.
The 46-page guide and 32-lesson course explain the why behind every number here.

Notice: these tools are educational estimates, not medical devices. They never diagnose PCOS or any other condition, and nothing you enter is stored or sent anywhere — every calculation runs in your browser. Only a clinician, with labs and your history, can diagnose.
