Start with the signs
The signs of PCOS.
PCOS means your ovaries make more androgens than usual, and most women with it also have high insulin. Those two things drive nearly every sign. You do not need all of them, and they often show up years apart. Tap the signs you have to see why they happen.
Nothing you tap is stored. This is a mirror for you, not a form for us.
Not all PCOS is the same
The types of PCOS.
There are four medical types of PCOS, named A to D, based on which of the three diagnostic signals you have. You will also see informal labels like insulin-resistant, adrenal or post-pill PCOS. Those describe what is driving your symptoms rather than a diagnosis. Tap a type to see what it means and where a plan would start.

Types A to D are the medical types from the 2023 international guideline, based on which Rotterdam signals you have. The other labels are informal. They describe the driver behind your symptoms, and many women fit more than one.
What the evidence says
What the common PCOS claims get wrong.
PCOS is a common and manageable reason for irregular ovulation, and many women with PCOS conceive. No diet makes it go away, and the 2023 guideline puts sustainable habits first. Where weight loss is relevant, 5 to 10 percent can help ovulation return. The pill is one tool among several, and PCOS reaches well beyond the cycle.
These summaries reflect the cited research and will change if the research changes.
What's driving your symptoms
How the PCOS cycle works.
Follow the cycle around once to see how each step feeds the next, and where daily habits can reach it.

Where daily habits can help
Insulin is the one part of this cycle that nutrition, strength training and sleep reach directly. When insulin sensitivity improves, cycles often become more regular, cravings ease and energy comes back.
The Rotterdam criteria
How do I know if I have PCOS?
PCOS is diagnosed with the Rotterdam criteria. There are three signals. In adults, having any two of the three is PCOS, once other causes such as a thyroid problem or high prolactin are ruled out. Tap each signal to see what it means.
Nothing checked yet. Tap each card that matches, and the verdict updates as you go.
This is a learning tool, not a diagnosis. Each signal needs proper testing to confirm it. For teenagers, only the first two signals count, because the ovary pattern is normal at that age.
Now the part you control
Six habits that improve insulin sensitivity.
Lifestyle is first-line care in the 2023 guideline. Strength training does the most for insulin sensitivity. Tap a habit to see what to do.

In the 2023 guideline, a 5–10% weight loss, where relevant, is linked to better ovulation, androgen and insulin markers, and habits you can keep matter more than any single diet.
What we track
Progress you can actually measure.
The first three are yours to track, and the last comes from testing. These numbers show progress even in weeks when you do not feel it.
Cycle length Ovulation signal
- What it is
- Your cycle length is a free signal you can track every month. For most adults a cycle runs 21 to 35 days.
- Why it matters here
- Cycles over 35 days or fewer than 8 a year point to irregular ovulation, the most visible sign of the underlying pattern.
- How we move it
- As insulin sensitivity improves, cycles often become more regular. This is the marker we watch most.
