That's the conclusion of the 2023 international evidence-based PCOS guideline. We're a wellness app that took it seriously and built for women who self-manage their PCOS, on your phone.

We surveyed 113 women with PCOS and ran 35 user research conversations about what wasn't working. The same answers came up over and over.
It feels overwhelming trying to keep track of all the things my body is doing.
Too many fields, too many apps, too many reminders for things that don't even apply to you.
Every app just asks if I'm pregnant.
They assume 28-day cycles and have never heard of hirsutism, even though it affects 70–80% of women with PCOS.
Preset symptoms don't really match, and it's hard to add my own.
Generic symptom lists miss what matters for PCOS. Without the right variables, there's no way to tell if something is working.
I thought tracking would make my doctor take me more seriously.
Fifteen-minute appointments. No clear timeline of when things started or what changed.
You choose only the variables, meds, and supplements you care about. Enable acne and inositol? That's your entire check-in. The variables, the questions, the interface: all built for PCOS, inspired by peer-reviewed research.
See changes over weeks and months. Walk into your next appointment with real data on your phone, not a vague memory of when something started.
61% of the women we surveyed had tried tracking before. There's still no comprehensive tool built for them.
Turn on the symptoms, meds, and supplements you care about. Skip the rest.
Swipe through your cards. Smart defaults mean you only update what changed.
Watch symptoms over weeks and months. Walk into your next appointment with real data.
You enable only the ones you care about. Tracking categories were chosen to reflect the symptoms PCOS women actually live with, informed by peer-reviewed research.
By region and severity. Forehead, chin, cheeks, jawline tracked separately so you can see how different areas change over time.
4 REGIONS · GAGS SCALETrack shedding severity over time using a standardized scoring system.

Join the beta →We met at Columbia. After 35 user research conversations and a 113-person survey, we kept hearing the same thing: the research on lifestyle interventions exists, but no one has built a tool that helps women who self-manage their PCOS actually use it.
Columbia Business School MBA · ex-McKinsey · Co-founder & CEO
I started Sachi at Columbia Business School after surveying 113 women with PCOS and interviewing doctors who treat them. The same thing kept coming up: the research on lifestyle interventions exists, but nobody has built a tool that helps patients actually use it. So I'm building what I kept hearing should already exist.

I'm an epidemiologist trained at Columbia's Mailman School of Public Health. My job is making sure every variable Sachi tracks maps to peer-reviewed PCOS research, and helping pick which studies are worth surfacing to you.
We're a small team, still in beta, and our early users are shaping everything we build. If that sounds like something you want to be part of, we'd love to have you.
