Cysta is the PCOS companion that actually scores your food. Log meals by photo, search, or barcode — every food gets a PCOS-friendly rating built for insulin resistance. Track your symptoms and your cycle (even when it's irregular), and walk into your next appointment with a doctor-ready report.
No account. No signup. Your data stays on your device.
