Menstrual Tracker

Bytimetracker

This tool helps you understand and predict your menstrual cycle with medical-grade accuracy. Simply enter the date of your last period, and it will automatically calculate your upcoming period dates, ovulation day, and fertile window using a precise luteal phase algorithm. The system adapts to your personal cycle history over time through median-based calculations and automatically detects irregular patterns for more reliable predictions.

You can view all your information in a beautifully designed, color-coded calendar that works perfectly on mobile and desktop. Log your daily symptoms, flow, sleep, or personal notes to make predictions even more accurate. The interface is simple, accessible, and fully private — all data stays safely on your device, with optional notifications to remind you of important cycle days.
