To all the women who rely on a calendar to track their menstrual cycles and plan for their periods, Once is a must-have period tracker. With its simplicity and functionality, Once keeps track of your irregular period cycle and cramps, making it easier for you to manage your cycle. In addition, Once provides valuable information about ovulation, fertility, birth control, and the possibility of pregnancy all in one convenient calendar.

Once's estimated period calendar becomes more accurate as you use it, thanks to its smart calculation system. You can view your estimated period, fertile days (with a high probability of pregnancy), and ovulation all in one step. The calendar also keeps a history of all your past period cycles for easy reference.

Take care of your fertility and ovulation meticulously with Once. The calendar allows you to see this important information at a glance, helping you better manage your reproductive health.

Once introduces a widget that lets you check your precious data more quickly. This is the first ever period calendar with a widget feature, making it even more convenient to view important information such as estimated period, ovulation, and percentage of pregnancy.

The percentage of pregnancy is calculated scientifically based on the lifespan of eggs (24 hours) and sperms (3-5 days). Once indicates the likelihood of pregnancy as "high" for one day before and after ovulation, and "moderate" for fertile days.

To help you prepare for important dates in advance, Once sends timely notifications with witty messages and alarms. You can also set up reminders for contraception pills. Plus, Once allows you to conveniently keep all your precious data, including recorded periods, intimate days, memos, and automatically calculated ovulation and fertility information. All you need to do is sign up to access these features.

With Once, it's not just about tracking your period; you can also record other intimate details such as the first day of your period and any symptoms or cramps you experience. Once ensures the privacy of these records with a lock function, so you don't have to worry about others accessing your personal information.

Once features a simple and stylish design that caters to women's preferences. The calendar's usability is enhanced by its attractive and user-friendly design. The estimated period and ovulation are presented in an easily accessible format, resembling a pretty planner you'd be proud to show off.

In addition to these special features, Once offers charming and interesting "Today’s Tip" that changes depending on your menstrual cycle. These tips include beauty recommendations, real-life know-hows, diet tips, and advice for maintaining healthy relationships.
