Founding members get early access to the iOS beta and help shape what we build. Tell us what matters to you, explore wellness programs inspired by peer-reviewed research, and build daily goals around them.
That's the conclusion of the 2023 international evidence-based PCOS guideline. Sachi was designed for women who self-manage their PCOS, every day, on your phone.
Most PCOS apps give you a period tracker and call it a day. Sachi is different. Tell us what you care about (acne, hirsutism, hair loss, weight, irregular cycles), and explore peer-reviewed studies related to your wellness interests.
See why a program caught your attention, learn what the study involved, and try daily wellness goals inspired by that research: nutrition targets, exercise plans, supplement schedules, sleep habits.
Wellness insights inspired by peer-reviewed research. Not medical advice. Always discuss changes with your provider.
Tracking categories were chosen based on peer-reviewed PCOS research. Track only what matters to you. The rest doesn't appear.
Log lesion counts by region: forehead, cheeks, chin, jawline, chest, back. See how different areas change over time.
Score unwanted hair growth across 9 body areas. Most apps don't even include this, despite it affecting 70–80% of women with PCOS.
Track thinning patterns over time using a standardized scoring system.
Log bleeding, flow, and cycle length. No predictions, no assumptions about when your period should come.
Track your prescriptions and supplements (inositol, vitamin D, spearmint, berberine, omega-3), not just a generic "supplements" checkbox.
Swipe to confirm nutrition, exercise, sleep, and mindfulness goals. Track streaks. Celebrate milestones. Mark flare days without breaking your streak.
Steps, sleep, workouts, and weight auto-sync. Goals auto-complete so you don't log twice.
See your week at a glance: goal progress, medication adherence, and program insights. Watch your data change over weeks and months.
Survey of 113 women with PCOS, plus 35 user research conversations. Same answers, over and over.
Every app just asks if I'm pregnant. They assume 28-day cycles and have never heard of hirsutism.
Survey · 113 women with PCOS
Preset symptoms don't really match. Without the right variables, there's no way to tell if something is working.
Survey · 113 women with PCOS
It feels overwhelming trying to keep track of all the things my body is doing across too many apps and spreadsheets.
Survey · 113 women with PCOS
I wish I could see all my PCOS data in one place without juggling three different apps.

Daniella Ueki (CBS MBA, ex-McKinsey) · Alishah Khan, MPH (Mailman School of Public Health)
Sachi is built by two women who met at Columbia. Daniella runs the company and the product; Alishah is the epidemiologist behind every variable we track. Between us, we make sure Sachi stays grounded in peer-reviewed PCOS research.
