Cystra brings your whole PCOS picture into one place — symptoms, cycle, labs, medications, food and movement — so you actually understand what's happening in your body, not just your weight.
WHY CYSTRA
Most PCOS apps hand you a diet plan and call it done. Cystra starts from the medical reality: PCOS affects your hormones, insulin, cycle and skin all at once, and managing it well means seeing the whole picture — not chasing a number on a scale.
TRACK WHAT ACTUALLY MATTERS
• Daily symptoms: acne, hair, mood, energy, sleep, cravings, bloating, pain
• Cycle tracking built for irregular cycles, with a realistic prediction range instead of false precision
• A labs vault for testosterone, fasting insulin, HbA1c, AMH and more — see your trends over months, not just one draw
• Medication & supplement tracking for metformin, inositol, spironolactone and more, with reminders and adherence
• Food and calorie tracking with PCOS-aware targets (calories, protein, carbs, sugar) built from your body and goals — a tool to inform you, not a rule to follow
Everything above is free to use — no trial, no paywall before you've even tried the app.
CYSTRA PREMIUM
• An AI coach that answers your questions grounded in your own data — and always shows its sources
• A growing library of PCOS-friendly, insulin-resistance-aware recipes and meal plans with grocery lists
• Illustrated, timer-based workouts you can adapt to your equipment, with exercise swaps
• Pattern reports that connect your symptoms, cycle, labs and medication adherence — export a clean PDF for your next doctor's visit
Cystra is built for understanding, not diet culture. Calories and weight are optional data points you're always free to hide — never a mandate, never the point.
Cystra provides educational content and is not a substitute for professional medical advice, diagnosis, or treatment. Always talk to your doctor about your PCOS care.
