Cystra is a compassionate journal for living with PCOS — built around your condition, not weight loss or fertility predictions.
LOG IN TWO TAPS
Record fatigue, acne, hair growth, hair shedding, pain and mood in seconds. There are no scores to win and no body goals to chase.
IRREGULAR CYCLES, NATIVE BY DESIGN
Log cycle dates without forcing a “normal” interval or pretending every cycle is predictable.
LABORATORY NOTEBOOK
Keep testosterone, AMH, fasting insulin, HOMA-IR, LH and FSH results with international units and the reference range printed by your own laboratory.
TREATMENTS AND REMINDERS
Record prescriptions and supplements exactly as agreed with your clinician, with optional reminders.
CYSTRA PRO
Explore lab trends and careful observations across symptoms, treatments and cycles. Prepare appointment questions, create a concise doctor PDF, export CSV and sync your journal through your private iCloud database.
YOUR DATA, YOUR CHOICE
The journal is local by default. Cystra contains no advertising and does not sell health information. Delete your journal from the device and iCloud in one step.
Cystra records and summarizes self-reported information. It does not diagnose, treat or replace professional medical advice.
