The reality
PMOS affects 1 in 10 women. Most are left to figure it out alone.
Up to 70% of women with PMOS remain undiagnosed worldwide. The average woman waits more than 2 years and sees 3 or more doctors before getting a diagnosis, and 85% are dissatisfied with the information they receive along the way.

Understanding PMOS
What is PMOS?
Polyendocrine Metabolic Ovarian Syndrome (PMOS), formerly known as PCOS, is a hormonal and metabolic condition affecting approximately 200 million women worldwide. It is about far more than ovaries. PMOS can affect your cycles, skin, hair, weight, energy, mood, fertility, and long-term metabolic health.
A PMOS diagnosis requires two of these three markers.
Irregular or absent ovulation
Cycles longer than 35 days, fewer than 8 periods a year, or no periods at all.
Elevated androgen levels
Visible as acne, excess hair growth or hair thinning, or confirmed on blood tests.
Polycystic ovaries on ultrasound
12 or more follicles or enlarged ovaries seen on imaging.
How Josie is different
Built around how PMOS actually works.
Josie is not a generic health app with a PMOS label. Every feature is designed around the complexity and variability of PMOS.
Symptom-first, not cycle-first
Most health apps put your period at the centre. Josie puts your symptoms there. Track 50+ PMOS-specific symptoms across 8 categories, from skin and hair to mood, energy, digestion, and cognition. Your cycle is part of the picture, not the whole picture.
Designed for irregularity
A 90-day gap between periods is not a missing cycle. It is a 90-day cycle. Josie's cycle tool is built around four named states — irregular, oligomenorrhea, amenorrhea, and medically regulated — so your experience is never treated as an error.
Your data becomes your voice
Josie turns your daily logs into structured appointment prep reports tailored to each specialist, from endocrinologists to dermatologists. Walk into your next appointment with a clear, evidence-based summary of what has been happening and what to discuss.
Every symptom matters. Even the ones no one talks about.
From acne and hair loss to brain fog, binge urges, and unrefreshing sleep, Josie covers the full range of what PMOS can look like. Log what you experience, rate the severity, and let the app find patterns you might not see on your own.
50+ symptoms across 8 categories
Physical, cycle, mood, energy, pain, digestive, appetite, and cognitive. Every part of your experience has a place.
Pattern recognition
Josie connects your symptoms to your cycle, medications, and lifestyle over time, turning daily logs into insight you can act on.

Still searching for answers
You suspect PMOS but do not have a diagnosis yet. You have been to multiple doctors and no one has connected the dots.
Diagnosed, navigating alone
You have a diagnosis, but your doctor has not prescribed digital tools or integrated care. You are managing PMOS on your own.
Dismissed but not giving up
A doctor has told you your symptoms are not serious, or that you should just lose weight. You know something is wrong.
Every screen tells part of your story
From symptom tracking to appointment prep, each feature is built to help you understand your body and feel more in control.

A few answers to help you understand how Josie works and what makes it different.
Polycystic Ovary Syndrome is a hormonal and metabolic condition affecting roughly 1 in 10 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.
Josie is a digital health companion for women with PMOS. It helps you track symptoms, understand patterns, prepare for doctor appointments, and manage your condition with evidence-based tools. It is not a generic period tracker. It is built specifically for the complexity and variability of PMOS.
Most health apps assume regular cycles and focus on fertility. Josie starts from symptoms, supports four different cycle states including absent periods, and generates specialist-specific appointment prep reports. It also includes advocacy tools for women who are still seeking a diagnosis or have been dismissed by their doctor.
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 tracking instead. Your cycle is one input, not the centre of the app.
