LunaCycle vs LadyOne

Every cycle tells a story. LunaCycle helps you read yours. Log your period, track symptoms, and get science-backed predictions -- all stored privately on your device, no account required. PERIOD & CYCLE TRACKING Log each period day with a single tap. LunaCycle automatically calculates your cycle length, predicts your next period, and shows you exactly where you are in your current cycle. FERTILITY WINDOW PREDICTIONS Know your fertile days before they arrive. LunaCycle uses your logged history to identify your ovulation day and fertile window, helping you plan with confidence -- whether you are trying to conceive or simply want to understand your body better. DAILY SYMPTOM LOG Record mood, flow intensity, physical symptoms, pain level, basal body temperature, water intake, and body weight. Every log builds a richer picture of your unique patterns over time. INSIGHTS & TRENDS Analyze your last 3, 6, or 12 months at a glance. See average cycle length, period duration, top symptoms, and BBT charts -- insights that help you spot changes and talk to your doctor with real data. CALENDAR VIEW A full monthly calendar shows period days, fertile windows, and ovulation markers at a glance. Tap any day for detailed phase information and logged symptoms. WHO IS LUNACYCLE FOR? LunaCycle is for anyone who wants a clear, honest view of their menstrual health -- whether tracking for the first time, planning a pregnancy, or monitoring patterns through perimenopause. Your data stays on your device. No cloud sync, no account, no data collection. LunaCycle works fully offline.

LadyOne is a gentle, private companion for your cycle, your pregnancy, and everything in between — built to stay entirely on your own device. Your body, your data, your peace of mind. CYCLE & FERTILITY Track your period, understand your phases, and see what's ahead. Predictions learn your own rhythm — never a stranger's. PREGNANCY, WEEK BY WEEK Follow your baby's growth, log how you feel, and know what's normal — and, just as clearly, what's worth a call. FAITH, IF YOU WANT IT An optional worship companion that understands your cycle and its rulings — entirely yours to turn on, or leave off. PRIVATE BY DESIGN • Everything you log lives on your iPhone — not on our servers, because we don't have any. • If you use more than one device, Apple's private iCloud sync carries it between them. We never see it. • No ads, no trackers, nothing sold. There is no third party in the room. • Erase everything, anytime — from the app, your iCloud, and Apple Health, in a single choice. SPEAKS YOUR LANGUAGE Available in English, Arabic, Persian, Chinese, Hindi, Russian, Spanish, Portuguese, Indonesian, French, Turkish and Urdu — with full right-to-left support, so every language feels native. No account required. Private by design. LADYONE PLUS LadyOne is free to use, and your cycle insights stay free. LadyOne Plus adds the pregnancy weeks with their trends, plus full doctor and prenatal reports as PDF — as a monthly or yearly subscription. Payment is charged to your Apple ID at confirmation of purchase. Your subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Privacy Policy: https://ladyone.app/privacy Terms of Use: https://ladyone.app/terms
