Sister Health

Built by women who live with these conditions. Symptom tracking made for endometriosis, adenomyosis, PCOS and PMDD — not generic wellness. Free to start.

Your body doesn’t follow the rules. Neither do we. Periods aren’t always predictable. Symptoms don’t always make sense. Sometimes you know there’s a pattern, but you just can’t quite work out what it is.

That’s where Sister Health comes in.

Sister Health helps you track symptoms, spot patterns and better understand your body. Whether you’re dealing with painful or irregular periods, symptoms associated with endometriosis, adenomyosis, PCOS or PMDD, or you simply want to understand what’s going on, Sister Health is designed to help you make sense of it all.

WHAT YOU CAN DO • Track pain, bleeding, mood, energy, bloating, sleep and more • Bring symptoms that can feel completely unrelated together in one place • Spot patterns over time that can be difficult to notice day-to-day • Turn what you’ve tracked into a clear summary for your next doctor or specialist appointment • Find straightforward reproductive health information when you need it

WHY SISTER HEALTH • Built by women, for women - with lived experience at its heart • Made with complex symptoms and non-textbook cycles in mind • Designed to grow with you through different stages of your reproductive health

Because you shouldn’t have to become an expert in your own health just to start understanding it.

Don’t just track it. Start understanding it.
