What is Allura?

Allura is an AI-powered period tracker designed specifically for people with irregular menstrual cycles. Unlike traditional trackers that assume a 28-day cycle, Allura uses machine learning to predict periods for cycles ranging from 21 to 90+ days. It's 100% private—all data stays on your device.

How is Allura different from other period trackers?

Irregular-cycle modeling: Built from the ground up for cycles that don't follow the "textbook" 28-day pattern, including PCOS and stress-related irregularities.
Symptom-to-phase insights: Correlates 40+ symptoms with your unique cycle phases to help you understand patterns over time.
Privacy-first architecture: No cloud uploads, no account required. Your health data never leaves your device.

Can Allura diagnose PCOS?

No. Allura is a tracking and prediction tool, not a medical diagnostic device. If you suspect you have PCOS or another health condition, please consult a healthcare provider. Allura can help you track symptoms and cycle data to share with your clinician.
