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. PREDICTIONS FROM YOUR BODY • Wrist temperature + sleeping heart rate fusion on Apple Watch • Ovulation estimates that adapt to your cycle, even when it's irregular • Fertile window and period predictions with honest confidence ranges • A clear daily view of where you are in your cycle and what's coming next TRYING TO CONCEIVE • A focused Conceive mode that highlights your estimated fertile days • Log ovulation tests, intimacy, and symptoms in seconds • Cycle insights that help you understand your luteal phase and timing • Switch to Pregnancy mode the moment you're ready EVERY LIFE STAGE • Cycle mode — periods, PMS, symptoms, flow, and patterns • Conceive mode — fertile-window planning for your TTC journey • Pregnancy mode — week-by-week tracking once you conceive • Perimenopause check-in — gentle tracking as your cycle changes PRIVATE BY CONSTRUCTION • Your cycle data is processed on your device first • Encrypted and anonymous by design — no account required to start • We don't sell your data. Ever. Your body is not a business model. • Delete everything at any time SMART, GENTLE REMINDERS • A quiet heads-up before your predicted period and fertile window • Daily log nudges you can shape or silence — Noor never shames you • Everything works offline; your data syncs privately with iCloud if you choose ASK NOOR + CYCLEPEDIA • Ask Noor, an on-device AI companion, answers your cycle questions privately • Cyclepedia: a calm, clearly written library about cycles, fertility, hormones, and your body 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.
