A gentle, private tracker that helps you discover what actually affects your symptoms — from your own everyday logs. No more guessing, no more being brushed off.
Gentle to use, genuinely useful — built around what actually helps with PCOS.
Cysterly studies your own logs to surface honest patterns — like “bloating runs higher on dairy days.” Personalized to you, never generic.
Tap how you feel, log your cycle, and snap a meal photo. Quick and gentle — even on your hardest days.
Snap a meal and a top-tier AI model reads the calories & nutrition for you — no tedious typing.
Set a kind, at-your-own-pace goal and cheer yourself on with encouraging progress — never shame.
Turn weeks of logs into a clean PDF of your symptoms, cycle & patterns — then send it straight to your doctor’s office in one tap. Walk in already prepared.
Everything lives on your phone. No account, no cloud, and we never sell your health data to anyone.
Three gentle steps — most days take under a minute.
Symptoms, food, cycle, sleep, weight — whatever feels right. Skip what doesn’t.
After a couple of weeks, Cysterly reveals what lines up with your symptoms — from your own data.
One tap sends your report straight to your doctor’s office — your appointment starts with evidence, not a scramble to remember.
Cysterly shows you correlations found in your own logs to help you have better conversations with your doctor. It does not diagnose, treat, or claim to find the cause of PCOS — and it never will. Just honest, personalized insight you can trust.
One subscription unlocks everything. Cancel anytime.
Yes. Your logs are stored only on your phone — there’s no account and no cloud, and your health data is never sold. Optional features you turn on (like AI meal-photo calories or weather) securely process only what they need, when you choose to use them.
No. Cysterly is a wellness tracker, not a medical or diagnostic tool. It surfaces patterns in your own data to help you and your doctor — it does not diagnose, treat, or determine the cause of PCOS.
No account, no sign-up, no password. Just download and start tracking. Everything stays on your device.
Cysterly runs a careful statistical analysis on your own logs to find reliable correlations — for example, a symptom that tends to be higher after certain foods or habits. It only shows patterns it’s confident about, and always frames them as correlations, not causes.
Cysterly is built for iPhone and Android. (Currently in final testing — see “Support” below to get in touch or hear when it launches.)
