Questions we hear most
A few answers to help you understand how Josie works and what makes it different. Nothing here is medical advice: if something about your health worries you, talk to your doctor.
Understanding PMOS
Polyendocrine metabolic ovarian syndrome (PMOS), formerly known as PCOS, is a common, long-term hormonal and metabolic condition affecting around 1 in 8 women of reproductive age. It can cause irregular cycles, acne, excess hair growth, hair thinning, weight changes, fatigue, mood changes and fertility challenges, though symptoms vary widely from person to person.
In 2026, after an international consensus process with patients, clinicians and researchers, the condition was renamed to describe what it actually involves: several hormone systems, metabolism and the ovaries, rather than cysts. Your diagnosis, the diagnostic criteria and treatments stay the same. Both names will be used during a transition of about three years.

Josie is a PMOS companion app that helps you track your symptoms, understand your patterns, prepare for doctor appointments and build a record of your health journey. Whether you are newly diagnosed, still looking for a diagnosis or managing PMOS long-term, Josie is designed to work for where you are.
Josie is built for PMOS from the start, not adapted from a period tracker. Irregular or absent cycles are expected, symptoms are tracked across the whole body, and your history becomes a Visit Brief or Evidence Report for your appointments. The articles in the app are reviewed by clinicians on our editorial board.
No. Many women with PMOS have highly irregular or absent cycles. Josie works just as well if you focus on symptoms, mood, energy or medication. Your cycle is one input, not the centre of the app.
Now. Josie is available on the App Store and Google Play.
Your data and safety
Yes. Your data is stored securely in the EU, encrypted at rest and in transit, and belongs only to you. Josie complies with GDPR, including the protections for health data. You can export or delete your data at any time. We never sell your data.
No. Josie is a wellness and symptom-tracking tool, not a medical device. It is designed to help you understand your body, spot patterns and prepare for conversations with your doctor. It is not intended to diagnose, treat, cure or prevent any disease.
Yes, when you choose to. You can download a Visit Brief or Evidence Report as a PDF, or share it with a secure QR link. You decide the reporting period and sections first, and your clinician does not need the Josie app.
