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.
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.
Most health apps weren't built for complex hormonal or cycle-related conditions. So you're left figuring it out alone.
Conflicting advice. Clinical jargon. Generic lists. It just leaves you more confused than when you started.
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.
Track your symptoms in a way that actually makes sense. Start seeing patterns. Connect with women who truly get it.
A glimpse inside
Designed for real life — not spreadsheets or guesswork.

Sister Health mission statement
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.
In the years that followed, I was passed from doctor to doctor, specialist to specialist. Appointments were expensive, often rushed, and rarely gave me real answers. My cycle was never normal. I had repeated ruptured cysts. My hormones were clearly out of balance. One doctor told me I had unusually high testosterone and joked that I had "strong blood like a boy."
I was 25 when I paid hundreds of dollars to see a gynaecologist, hoping — finally — for clarity. She glanced at a scan and told me it was impossible for me to have polycystic ovaries because my cysts didn't look like a "pearl necklace." She suggested I probably had endometriosis instead.
No follow-up. No clear plan. Just another possible diagnosis added to the list.
I kept being told to lose weight, eat better, try getting pregnant — because "pregnancy can help endometriosis." Nothing addressed the root cause. Nothing gave me answers. I felt like I was constantly chasing clarity inside a system that wasn't built to understand women like me.
Then everything changed.
I experienced an ectopic pregnancy that almost cost me my life. During emergency surgery, doctors had to remove my left fallopian tube. Before they put me under, I asked them to look for endometriosis. They told me it was unlikely they'd find anything. When I woke up, the surgeon told me something very different.
Stage three endometriosis. Lesions across my hips, bladder, and abdomen. And for the first time — after more than a decade — a doctor looked at me and said: "Now I understand why you've been in so much pain."
I cried. Not just from relief, but from grief for every year I'd spent doubting myself.
Even then, the endometriosis wasn't removed. The solution offered was the same one so many women are handed — hormonal birth control and a Mirena to manage symptoms. Not to fix. To manage.
Lying in that hospital bed, I didn't just feel the weight of my own journey. I thought about every woman who had been told her pain was normal. Every woman who had paid for appointments that led nowhere. Every woman who had Googled her symptoms at 2am, desperate for an answer, and found nothing reliable.
If navigating this system was this hard for me — someone who fought, who pushed, who kept showing up — what was it like for women who didn't have that fight left in them?
That question is why I built Sister Health.
Sister Health is for every woman who has ever been dismissed, confused, or made to feel like her pain was in her head. It's a place where information is clear, conversations are honest, and no one has to go through this alone.
Because no woman should have to spend years feeling unheard while trying to understand her own body.
And no one should have to almost lose their life before finally being believed.

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.
So I learnt to push through it.
I was put on the pill early on — not to understand what was going on, but to manage it. And for years, that's all it was. Managing symptoms. No real answers.
When I came off the pill, I thought I was doing the right thing for my body. Instead, the pain came back worse than I remembered — and with it came acne along my jawline that I'd never had before. My skin, my cycle, my energy — everything shifted at once. It felt like my body was speaking a language I didn't know how to read.
When I finally received my endometriosis diagnosis, it wasn't handed to me with a clear plan. It was handed to me with a prescription and a "good luck." So I did what so many of us end up doing — I figured it out myself.
I started tracking what I ate. Noticing patterns. Learning which foods triggered flares and which ones gave me some relief. Over time, I adopted an anti-inflammatory diet — not because a doctor guided me there, but because I listened to my own body, log by log, day by day.
Two years on, I'm still working through it. The jawline acne, the hormone shifts, the question of what exactly is triggering what — it's an ongoing puzzle. And honestly? Some days it's exhausting to still be figuring it out.
But tracking has given me more clarity than any appointment ever did. And I keep thinking — imagine doing this with other women beside you.
I would have loved a community. A place where I didn't have to explain from scratch why gluten wrecks my week, or why jawline breakouts might be a hormonal sign, or why I cancelled plans again.
That's the part no app ever gave me. And that's exactly the part we're building into Sister Health.
A space where you can track what matters, spot your own patterns, and find women who understand what you're going through — without having to prove how much it hurts first.

Get Early AccessThese are from conversations we've had with women in our community.
"I've been told it's normal so many times I stopped asking."
"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.

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.
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.
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.
