About
Noor is a calm, private period and ovulation tracker that predicts your cycle from your body — not just a calendar.
Most apps guess your fertile window by counting days. Noor goes further. On Apple Watch, it reads your overnight wrist temperature and sleeping heart rate while you sleep, then fuses those signals with your logged cycles to estimate ovulation and your fertile window. No thermometer. No early-morning temping. No extra effort — just wear your watch to bed.

• Wrist temperature + sleeping heart rate fusion on Apple Watch

DESIGNED TO FEEL CALM
Noor's Living Light design is quiet, warm, and beautiful — a tracker that feels like a sanctuary, not a billboard. No clutter, no judgment, no noisy feed. It's fast, fully native, accessible, and just as beautiful in dark mode — on iPhone and on your wrist.
WORKS WITH APPLE WATCH
Wear your watch to sleep and Noor handles the rest. Wrist temperature and heart-rate trends are read automatically through Apple Health, with your permission, and stay under your control.
A NOTE ON WHAT NOOR IS
Noor is a wellness and education app. Predictions are estimates based on your data and are intended for tracking and planning, not for medical use. Noor is not a medical device, does not provide medical advice or diagnosis, and must not be used as contraception or to prevent pregnancy. Always consult a healthcare professional for medical questions.
Start tonight: log your last period, wear your watch to bed, and wake up to a tracker that actually understands your cycle.
Noor — your cycle, illuminated.
