Women deserve better tools for navigating their health.
We track more about ourselves than ever before. What we eat. How we sleep. How we move. Yet we’re still left trying to understand what it all means.
The most revealing patterns often emerge between signals, not within a single one.
01 — Get the known right.
If the evidence exists, use it. Female-specific reference values, age and life-stage adjustments, appropriate nutrition targets, and cycle calculations grounded in what we actually know.
02 — Never invent the unknown.
An estimate should say it’s an estimate. Missing data should stay missing. Evidence should show its strength. Patterns would rather tell you “we don’t know” than quietly fill in the blank.
03 — Let your history earn the insight.
Patterns doesn’t assume something is true about you because it’s common in women or associated with your cycle phase. Personal findings come from your own record, once there’s enough evidence to support them.
04 — Look at the whole record.
Nutrition, cycle, sleep, mood, symptoms and movement can tell a different story in context than they do alone. Patterns was built to analyze across them, rather than treating each as a separate health score.
Patterns started with one I missed in myself.
Since I was a teen I had symptoms that seemed disconnected: physical changes, severe mood swings, extreme stomach pain, and I didn’t quite feel like myself for a few days every month.
I tried to understand it the way most of us do: I spoke to doctors, I journaled, tracked, searched and started cross-referencing dates against my cycle. It was an enormous amount of work, made harder by the fact that the days I most needed to observe clearly were the days I was least able to.
When my mood shifted, my dad noticed before I did. He’d ask if my period was coming, which annoyed me. But he was right. His observation ultimately led to my PMDD diagnosis and the idea behind Patterns.
Sometimes the missing piece isn’t more data. It’s a second set of eyes.
But a doctor, friend, or family member can’t watch every meal, symptom, night of sleep, workout, mood shift, cycle change, or life stage with you. And no one should have to manually stitch all of that together across apps, calendars, and journals themselves.
I built Patterns to work with the information we’re already collecting about ourselves.
Not to tell us what’s wrong. To help us see our own health more clearly.
A note on PMDD
Premenstrual dysphoric disorder is a real, diagnosable condition affecting an estimated 3–8% of women. Marked mood swings, physical symptoms such as pain and bloating, and a sense of being overwhelmed in the days before a period are all among its criteria in the DSM‑5. Which is to say the disconnected list above is, to a clinician, one thing. PMDD was not added to the DSM‑5 until 2013, and the World Health Organization did not list it in the ICD‑11 until 2019.
Patterns is not a treatment for PMDD or for anything else, and nothing in it is a diagnosis. If this sounds like your life, it is worth raising with a doctor.
