Something that actually listens

Stop guessing what's wrong. Start understanding your body.

Track symptoms. Spot patterns. Finally feel supported.

Built by women who've lived it — and shaped with you from day one.

No spam. Just updates you'll actually want.

Free to join — takes 10 seconds, no credit card, no spam, ever.

Your data is private. We'll never share it. See our privacy policy.

You've been dismissed. Misdiagnosed. Told it's 'just hormones'.

If you've spent years searching for answers — you're not imagining it. You've been overlooked for far too long.

We know this feeling, because we've experienced it too.

Years without answers

Many women spend years trying to get answers. Endometriosis alone takes an average of 8 years to diagnose. It shouldn't take that long to understand your own body.

Feeling like no one gets it

Most health apps weren't built for complex hormonal or cycle-related conditions. So you're left figuring it out alone.

Too much noise, no real answers

Conflicting advice. Clinical jargon. Generic lists. It just leaves you more confused than when you started.

This is for you if…

  • You've been told "it's normal" — but it doesn't feel like it.

  • You've left appointments with more questions than answers.

  • You track symptoms in notes apps, spreadsheets, or your head — because nothing else fits.

  • You know something isn't right — even if you can't explain it yet.

  • You're tired of figuring this out alone — and ready for something that actually gets it.

Everything you've been trying to figure out — finally in one place.

Track your symptoms in a way that actually makes sense. Start seeing patterns. Connect with women who truly get it.

A glimpse inside

Something we've noticed

You might notice fatigue and bloating feel heavier around this time. If everything feels a bit more overwhelming than usual — you're not imagining it. The bloating and the exhaustion are connected, and your cycle is the reason why.

What makes this different

Not just tracking

Sister Health helps you understand what your data actually means — so you can see patterns, make sense of your symptoms, and feel less in the dark.

Not generic — built for conditions that get ignored

Designed specifically for endometriosis, adenomyosis, PCOS, PMDD, and more — not a standard period app with a pink theme.

Not overwhelming — simple, clear, actually helpful

No jargon, no endless data entry. Just a calm, clear space where you can log what you're feeling and start to see what it means.

Built with you from day one

You're not just a user — you're part of how we shape this. Your experiences, your feedback, and your voice genuinely matter here.

You deserve to understand your own body.

Not in years. Not after a dozen appointments. Now.

We built Sister Health so you can finally understand your body — without feeling dismissed, confused, or alone.

Sister Health mission statement

Our story

Why we're building Sister Health

Two different journeys. The same experience of not being heard.

Isabella

Diagnosed: Endometriosis, Adenomyosis, PCOS

I was 15 the first time I ended up in hospital with pain that stopped me in my tracks.

Doctors were focused on my appendix. My mum pushed them to check my ovaries. They were reluctant — but eventually, they did. That's when they found my first ruptured ovarian cyst.

That was the moment the words polycystic ovaries entered the conversation about my body. It would take over a decade before anyone actually listened to what that meant.

Jade

Diagnosed: Endometriosis

I remember sitting in the school nurse's office, in so much pain I couldn't move — sometimes even being sick from it.

I was told it was normal. That periods are just painful. That I'd grow out of it.

You're not the only one who's felt this way…

These are from conversations we've had with women in our community.

"I've been told it's normal so many times I stopped asking."

— Instagram message

"I don't even know what's wrong. I just know something isn't right."

"I've spent years Googling symptoms at 2am. I just want somewhere that actually gets it."

"Every doctor visit I leave feeling more confused than when I went in."

"I wish I'd had something like this when I was first trying to figure out what was happening to my body."

This is exactly why we're building Sister Health — and why we're building it with you.

Be part of something built for you — before we launch

A few things you might be wondering…

Is Sister Health free to join?

Yes — joining the waitlist is completely free. You'll be the first to hear when we launch and how to get involved.

When can I start using it?

We're currently building Sister Health and getting ready for our first early access release. If you join now, you'll be among the first to try it, shape it, and be part of it from the beginning.

Is this for my symptoms/condition?

Sister Health is for women navigating things like endometriosis, adenomyosis, PCOS, PMDD, fibroids — or just feeling like something isn't right. If you've ever felt dismissed, confused, or like you're figuring it out alone… this is for you.

What happens after I sign up?

We'll only email you about Sister Health — things like updates, early access, and ways to get involved. No spam, no selling your data. Ever. You can unsubscribe anytime. Read our privacy policy for more detail.

Do I need a diagnosis?

No. Sister Health is for anyone who feels like something isn't right — whether you have a diagnosis, are still searching for one, or just know your body well enough to know you deserve better answers.

What if I don't know what's wrong?

That's exactly who Sister Health is built for. You don't need to have the answers yet — that's the point. Track what you're experiencing, and over time the patterns start to speak for themselves.

How is this different from other apps?

Most cycle apps were built for typical periods. Sister Health was built for the messy, complicated, often invisible reality of conditions like endo, PCOS, PMDD, and more. It's not just about tracking — it's about understanding. And feeling like something finally gets it.
