HormoneOS
Understand your body.
Own your health.
A weekly report on what your body is actually doing — written like a friend who reads your data, not a doctor reading a textbook. Built for the women who got tired of being told it's nothing.

How it works
Three small things, one big picture.
Apple Health, read-only
HormoneOS reads your cycle, sleep, HRV, heart rate, and temperature. We never write to Health, and we never ship your raw data anywhere.
60 seconds of voice, on-device
Tap the mic and talk about your day. Apple's on-device speech transcribes it locally — your audio never leaves your phone. We only send the transcript. Or fill out the daily details by hand.
A real weekly report, every Sunday
Based on an analysis of 28 days of your data, you'll see the patterns — calibrated, specific, with the exact questions to bring to your doctor.
Why this exists
Because "you're fine, it's just stress" isn't an answer.
Perimenopause arrives a decade before most of us are told it exists. The hot flashes, the 3am wake-ups, the brain fog, the mood swings — all of it shows up in your body's data days, sometimes weeks, before it shows up in the appointment.
HormoneOS notices. It looks at your cycle, your sleep, your HRV, what you said about your day, and finds the threads that connect them. Then it gives you the specific words to bring to your doctor — because you should walk into that appointment with a list, not a hope.
You're not imagining it.

HormoneOS describes patterns in your data. It does not diagnose, treat, or cure any condition. Always talk to a qualified doctor about anything that feels off.
