## Joii Period Evaluation Description
Joii is the first period app that actually measures your flow – no more guessing, no vague tracking.

Simply scan your Evaluation Pad with your phone and get real numbers on your period volume and clot size, powered by AI.

Whether your periods are light, heavy, or unpredictable, Joii gives you accurate, medical-grade insights you can share with your doctor - helping you understand your health like never before.

Why Joii?
• Measures your actual blood loss (not just “heavy” or “light”).
• Tracks clot sizes for better clinical conversations.
• Class I Medical Device (UK-certified).
• Backed by real science, designed for real people.

Because knowing your flow is power – and you deserve better data about your body.

Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. Do not rely solely on this app for medical decisions. Consult your doctor before making any decisions related to your health.
