PMOSense for PCOS and irregular cycles
A PCOS cycle tracker built for irregular patterns
PMOSense helps you record the cycle signals that matter to you in one place, rather than relying only on a standard 28-day calendar assumption.
Free to use. No subscription required. Available on iPhone and iPad via the App Store, or as a web app in your browser.

Why multiple signals matter
Why PCOS cycles can be harder to track
Cycle length and ovulation timing can vary for people with PCOS, so calendar dates alone may not offer enough context. Logging the signs you notice over time can give you a more complete personal record to review.
This is general health information, not medical advice. The World Health Organization’s PCOS fact sheet describes irregular menstrual periods and abnormal ovulation among possible features of PCOS. It does not endorse PMOSense.
Your record, in one place
What you can track with PMOSense
Choose the information that is useful to you, then keep it alongside your cycle history instead of scattered across photos, notes and calendars.
Symptoms and daily context
Keep symptoms, mood and stress, medication, supplements and notes beside your cycle record.
History and patterns
Review cycle history and logged patterns across days, weeks and multiple cycles.
A clearer distinction
More than calendar predictions
PMOSense brings together what you log and provides estimated cycle and fertility context from those signals. Keeping the difference clear helps you use the app as a tracking tool—not a medical test.
Observed or logged information
- Period dates and flow
- LH test results
- BBT and cervical fluid observations
- Symptoms, mood, stress and notes
PMOSense estimates and context
- Period predictions
- Estimated fertility context
- Pattern interpretation from logged data
- Ovulation-related context, where applicable
Built beyond one average
Designed for irregular cycles
PMOSense does not ask you to treat every cycle as if it follows the same 28-day pattern. It helps you organise the signals you log and compare your own history over time, whether cycles are long, skipped or simply variable.
Understand patterns over time
A longer personal history can make appointments and your own reflections easier to prepare for. It does not identify medical conditions or replace clinical assessment.

Medical boundaries
Tracking, estimates and context—not diagnosis
PMOSense uses the information you log to provide tracking, estimates and context.
It does not diagnose PCOS or PMOS, provide medical diagnosis, medically confirm ovulation, or replace professional medical advice. Speak with a qualified healthcare professional for medical concerns, diagnosis or treatment.
