PMOS doesn't pause between appointments.Cyster doesn't either.
Private care between PCOS (now PMOS) appointments. Make sense of labs and cycles, prepare for the next visit, and manage the daily decisions in between.
Three surfaces, one thread.
- 01
Atlas
Tap any symptom. See which other parts of your body it connects to.
- 02
Pattern
Twelve questions. Find out which arm of PMOS may be loudest today.
- 03
Companion
Carry your labs, cycles, and questions across visits — privately.
Care happens in the days no one is watching.
For women with PMOS (or PCOS) — newly diagnosed, decades in, or somewhere between.
A PMOS appointment may last fifteen minutes. Cyster is built for the time in between, so the next clinical conversation starts further along than the last one ended.
- 01
Preserve the context
Keep the details that usually disappear between visits: changes, flares, questions, labs, decisions, and what you tried.
- 02
Understand the longer arc
Not every symptom matters every week. Cyster helps make the longer arc easier to understand.
- 03
Prepare the next conversation
Plain-language guidance helps turn lived experience into better questions, better notes, and better clinical conversations.
One body. One map. The wiring behind your symptoms.
PMOS does not show up as a single symptom. It shows up as a system. Start anywhere; follow the lines.
Open the Body AtlasEvery node grounded in current evidence and reviewed for clinical clarity.
Twelve questions. One named pattern.
Twelve questions translate how PMOS feels into a clinically informed read. You leave with a named pattern and a way to bring it into your next visit.
Take the Pattern AssessmentA private companion that holds the thread.
Cyster remembers what your appointments forget: labs, cycles, the question you meant to ask. It does not push protocols.

Lab context.Helped surface what may be worth asking about, instead of assuming every symptom is “just PMOS.”
- 02
Medication questions. Helped organize side effects and possible interaction questions for a clinician or pharmacist.
- 03
Daily decisions. Made food and energy choices feel neutral, practical, and easier to act on.
Mary makes sure Cyster can actually help.
Every surface Cyster ships is reviewed for clinical clarity and safety before it reaches a member.

- Pattern logic is grounded in peer-reviewed evidence.
- Companion responses follow content standards Mary writes herself.
Cyster does not diagnose, treat, or replace your healthcare team.
Meet the foundersThe space between appointments is where PMOS actually lives.
Pattern is not a cure. It is what gives the next decision a shape. You begin to read your body the way Cyster reads the research.
Managed, not just monitored.
Care that travels with you, between visits.
