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.

About

SuppLab

Features
Read full description

SuppLab is a supplement tracker for people who take a few things every day and want to know two things: what it all costs, and whether any of it is making a difference. TRACK YOUR STACK • Log every supplement and vitamin you take, with timing and on/off cycles • Daily reminders that fit your routine — morning or evening • Monthly and yearly cost, so you always know what your stack costs • Stack check: flags pairs that shouldn't be taken together (zinc + iron, and more) • Label scan: point the camera at a label to add what's in it A LIBRARY YOU CAN CHECK • 111 supplements, from magnesium and creatine to ashwagandha and omega-3 • Evidence graded strong, moderate or limited — every reviewed entry links its PubMed sources • What to expect and when, cautions, and drug interactions COMPARE TAKE-DAYS WITH SKIP-DAYS • Pick one supplement and one primary measure: sleep, HRV, resting heart rate, energy, focus or mood • SuppLab builds a randomized 14–28 day take/skip schedule and reminds you each day • Sleep, HRV and resting heart rate come from Apple Health; energy, focus and mood take a 10-second check-in • At the end you see the average difference between take-days and skip-days with its uncertainty — or a plain "not enough data" when there isn't enough This is a personal comparison, not a clinical trial. It can't prove cause and effect, and it is not medical advice. LONG-TERM VIEW • Your last 28 days of Health data compared with the baseline you started from • Export everything as CSV to share with your doctor PRIVATE BY DESIGN • No account, no sign-up, no server. Everything stays on your iPhone. FREE AND PREMIUM The library, label scan, stack, reminders and cost tracking are free. Take/skip comparisons, result reports and the long-term view are part of SuppLab Premium (annual with a free trial, or weekly). SuppLab is an educational tool for healthy adults. Consult a healthcare professional before starting or stopping any supplement.
