Actually understand what's happening
Track your symptoms in a way that helps you see patterns and changes over time — not just log data.
The app
Everything you've been trying to figure out, in one place.
Track symptoms. Spot patterns. Finally feel supported.
Free on iOS and Android
The essentials.
What you log is yours — used to show you your own patterns and build your Doctor's Report, nothing else.
Information without the overwhelm
Explore clear, credible women's health information, written to actually make sense.
Find people who get it
Join the Sister Health Facebook community to connect, share and feel less alone.
Patterns you can actually use
See what tends to show up together and what changes across your cycle, based on what you log.
Take the bigger picture to your appointment
Turn what you've tracked into a downloadable Doctor's Report, with your cycle snapshot, patterns you've confirmed and potential questions to discuss with your healthcare professional.
Tracking that fits your life
Log symptoms in seconds, without it feeling like another task.
How it works
Four steps, from "something's off" to "here's what I've got."
1
Check in
Log how you feel, in about 30 seconds.
Rate your pain, mark where it is, and describe it — then add mood, energy and sleep if you want to. A few simple taps and the day is captured, so nothing gets lost between appointments.

Patterns & insights
See what keeps repeating — and confirm what's true.
As you log, Sister Health surfaces patterns from your tracking history and shows them back to you. You confirm what fits — these are observations from your own data, never a diagnosis.
Example insight: "You've been logging pelvic pain before your period starts — not just during it. This has shown up across 4 of your last 5 cycles. Keep tracking to see whether this pattern continues."

Doctor's Report
Walk in with evidence, not just "I feel awful."
Turn months of logging into a clear, one-page Doctor's Report — average cycle length, peak pain days and the patterns you've confirmed. Export it as a PDF and bring it to your appointment, so the conversation starts with your data instead of your memory.

Resources & Sister Club (soon)
Real answers, and people who get it.
Browse a growing resource library — pain, work, lifestyle, mental health, treatments — written like a human, not a textbook. And Sister Club, our in-app community, is coming soon — a place where you won't have to explain from scratch why this week has been hard. Until it opens, our community is on Facebook.
Built for the conditions that get dismissed.
Endometriosis, adenomyosis, PMOS (PCOS), PMDD — and any cycle that doesn't follow the rules.
Explore the conditions we support →Good questions.
Does Sister Health diagnose anything?
No. Sister Health helps you track your symptoms and shows you patterns in your own data. It doesn't diagnose or give medical advice — that's a conversation for you and a qualified healthcare professional, and the Doctor's Report is there to help you have it.
How does the pattern detection work?
As you check in over time, the app looks for things that recur — like pain that often appears on certain cycle days — and shows them to you as observations. You decide whether each one is true for you, so your report reflects your reality, not a guess.
Which conditions is it for?
It's built for endometriosis, adenomyosis, PMOS and PMDD — and works for general cycle tracking too. If your cycle is complicated, this was made for you.
What does it cost?
