LunaCycle - Period Tracker

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.
