Cylo - Period Tracker App for Android

Cylo — Personalized Cycle Care for Android

Cylo is a free Android app that helps people track menstrual cycles and gain clearer insight into their reproductive health. Whether the goal is to plan for pregnancy, avoid conception, or simply understand natural patterns, Cylo gives users tools to monitor their cycle and make informed choices.

How the app learns from you

The app improves its predictions over time by learning from each person's history. It records patterns and uses that data to forecast upcoming periods, fertile windows, and other cycle-related events more accurately as more entries are added.

Main capabilities

• Secure backups and easy data restoration so your history stays available across devices.
• Built-in reminders to alert you about upcoming periods, fertile days, or medication schedules.
• A compact knowledge center with articles and tips about menstrual and reproductive health.
• Automatic estimation of fertile windows to support family-planning decisions.
• Custom logging for moods, symptoms, and everyday habits to capture the full context of your cycle.
• Clear forecasts for upcoming periods so you can plan activities and appointments.

Design and privacy

Cylo presents information in an intuitive layout that makes navigation straightforward for new and experienced users alike. The developers emphasize data privacy, keeping personal records protected and giving users control over backups and sharing.

Who benefits from Cylo

This app is suitable for people at any stage of life who want an accessible, all-in-one cycle tracker—helpful for those tracking natural fertility, using contraception, or monitoring health trends over time.
