Period Calendar, Cycle Tracker is an elegant menstrual cycle tracker designed to help you understand your body and take control of your reproductive health. Whether you're planning pregnancy, managing contraception, or simply tracking your cycle regularity, this intuitive app delivers accurate predictions and actionable insights tailored to your unique patterns.

Known as a CE Class I Medical Device (EU), Period Calendar, Cycle Tracker processes your daily entries to predict upcoming periods, identify fertile windows, and monitor ovulation with precision. The app learns from your cycle history, adapting its algorithm to match your body's natural rhythm—so predictions become more accurate over time. At a glance, your home calendar reveals non-fertile days, fertile periods, ovulation timing, and expected cycle dates in a clear, visual layout.

Capture every detail that matters to your health. Log flow intensity, intercourse, symptoms, mood changes, temperature, weight, medication, and PMS signs day by day. Discrete notifications keep you prepared for what's coming next, while PIN code protection ensures your most intimate health data stays private. Need to switch devices or back up your information? Quick restore functionality protects your records against loss or replacement.

Period Calendar, Cycle Tracker supports every chapter of your reproductive life. Activate Pregnancy Mode for dedicated insights about your baby's development, body changes, and pregnancy symptom tracking—plus generate shareable doctor's reports. If you're entering perimenopause, switch to Perimenopause Mode to monitor hot flashes, night sweats, mood fluctuations, and cycle irregularities while tracking patterns that help you stay informed during this important transition.

Customize tracking to match your needs. Adjust prediction intervals, set luteal phase length, track cervical observations, choose measurement units, or change your week's first day. For teens or those preferring simplified tracking, Abstinence Mode hides ovulation, fertility, and intercourse data—keeping the focus on basic cycle awareness.

Fertility tracking powered by sophisticated algorithm-based predictions helps you understand your most fertile days, supporting informed decisions about conception or contraception. The calendar excels at anticipating key dates that matter to you, adapting continuously as your cycle data accumulates.

Remember: Period Calendar, Cycle Tracker is a support tool, not a medical device replacement. Always consult qualified healthcare professionals for diagnosis, treatment, or medical advice. Use additional contraception methods if preventing pregnancy. Predictions are estimates based on your entries and natural biological variation may affect accuracy.
