Noor is a calm period and cycle tracker for recording symptoms, understanding patterns and seeing transparent estimates for upcoming periods, ovulation and the fertile window.
TRACK YOUR CYCLE
Log periods, flow, symptoms, moods, notes and other supported cycle observations. Review entries on a clear calendar and adjust reminders to suit you.
ESTIMATES WITH CONTEXT
See estimated period, ovulation and fertile-window timing together with the information and uncertainty behind the estimate. Cycle timing can change, and Noor does not present a prediction as a confirmed biological event.
OPTIONAL HEALTH CONNECT
With your permission, Noor can read supported Health Connect signals such as wrist temperature and resting heart rate. You choose whether to connect them and can change access in Health Connect.
FOR CHANGING STAGES
Use supported views for trying to conceive, pregnancy and changing or perimenopausal cycles. These modes organize logs and educational context; they do not diagnose a condition.
CYCLEPEDIA AND ASK NOOR
Read plain-language education about cycles, hormones, ovulation and symptoms. Ask Noor can help you explore general educational questions, but its answers are not a diagnosis or a replacement for professional care.
SENSITIVE DATA AND ADS
The free version is ad-supported. Ads are limited to generic educational or settings areas, including Cyclepedia, and do not use period dates, symptoms, fertility estimates, Health Connect data, journal content or questions to select, personalize or measure ads. Noor does not show full-screen interstitial or rewarded ads.
Verified monthly or annual paid users and verified prior purchasers are ad-free. Active Ario Pass also removes ads while active. Google Mobile Ads may process device, app-interaction and diagnostic data for ad delivery, measurement, security and fraud prevention.
IMPORTANT HEALTH INFORMATION
Noor is a wellness and education tool, not a medical device. Estimates can be wrong and must not be used as contraception or to prevent pregnancy. Noor does not provide medical advice, diagnosis or treatment. Contact a qualified healthcare professional for medical questions or concerning symptoms.
