Guardian Angel

Your body has been
sending signals
your whole life.

Guardian Angel Women's Health turns your bathroom into the most consistent health tracker you've ever had — working every day, across every life stage, without you having to remember to use it.

What it does

Continuous. Passive.
Clinically validated.

A woman's health changes constantly — across the menstrual cycle, through pregnancy, into perimenopause and beyond. These changes carry vital information. But they happen in private, are rarely captured consistently, and are often dismissed or missed entirely. Guardian Angel changes that — passively, without friction, across your whole life.

Hormonal cycle & fertility

Understand your cycle — not just track it.

Urinary metabolites reflect oestrogen and progesterone fluctuations every day. Guardian Angel maps your cycle regularity, ovulation windows, and hormonal shifts — giving you insight into your fertility window, and the relationship between your cycle and your energy, sleep, and mood.

"Daily hormonal data, without a blood test or a strip."

Perimenopause & menopause

The transition, tracked continuously.

Perimenopause can last years, and the experience is different for every woman. Guardian Angel tracks your hormonal transition continuously — giving you real data on what's changing, when, and how it correlates with your symptoms. Instead of describing how you feel, you can show what's happening.

"Understand what's shifting before symptoms become disruptive."

Metabolic & chronic conditions

Data that advocates for you.

Conditions like PCOS, endometriosis, and autoimmune diseases are hormonally influenced, cyclically variable, and chronically under-researched. Guardian Angel gives women with these conditions a daily window into how their health fluctuates — and the longitudinal record to advocate for better care.

"Build a health record that speaks for itself when words aren't enough."

Who it's for

Every life stage.
One product.

Women's Health serves women across the full arc of their health journey — from reproductive years and fertility through perimenopause and beyond.
