Sachi Health Daily Check-In

Sound familiar?

We surveyed over one hundred women with PCOS about what wasn't working. These 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.

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.

So we built Sachi differently.

You choose only the symptoms, 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 from day one, grounded in 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 asked had tried tracking before, but there's still no comprehensive tool built for them. PCOS affects 1 in 10 women of reproductive age.

Pick what matters. Track it in 30 seconds.

Medication adherence and insights

What you can track

You enable only the ones you care about. Our variables come from peer-reviewed PCOS research.

Your symptoms

Acne

By region and severity. Forehead, chin, cheeks, jawline tracked separately so you can see which areas respond to treatment.

Hair loss

Log shedding severity over time.

Hirsutism

Track unwanted hair growth by body area. Most period trackers don't even include this as an option, despite it affecting 70 to 80% of women with PCOS.

Your cycle & body

Cycle

Built for irregular cycles. Won't assume 28 days.

Body composition

Weight, BMI, waist-to-hip ratio, body fat, and muscle mass. Syncs automatically with Apple Health so you don't have to log manually.

Your regimen

Medications

Spironolactone, metformin, birth control. Track adherence with reminders.

Supplements

Inositol, omega-3, vitamin D, spearmint, berberine. Log daily.

In development Mood tracking, personalized lifestyle recommendations, exercise, sleep, and nutrition.

Why we're building this

Daniella Ueki
Co-Founder & CEO

I started this at Columbia Business School after surveying over a hundred women with PCOS and interviewing doctors who treat it. The same thing kept coming up: the research on lifestyle interventions exists, but nobody has built a tool that actually helps patients use it.

My co-founder is an epidemiologist (also Columbia, MPH) who makes sure the variables Sachi tracks are grounded in published evidence. Between her research background and my experience in strategy consulting at McKinsey, we're building what we kept hearing should already exist.

We're a small team, still in beta, and our early users are shaping everything. If that sounds like something you want to be part of, we'd love to have you.
