・Four Menstrual Cycles and Period Prediction
The four cycles—follicular phase, ovulation phase, luteal phase, menstruation phase, and female hormone cycle—are color-coded in a circular pattern, making it easy to understand your menstrual cycle. Based on your recorded period start date and cycle, it predicts the start date of your next period. Convenient as it can be used as a reference even without measuring basal body temperature.
・Period Management
You can record menstrual flow (heavy/light), menstrual pain level, and whether or not you took medication. You can review your past periods in "Review." As you accumulate records, trends are displayed in a list for each day, such as day 1, day 2, etc. Furthermore, predictions of menstrual flow and menstrual pain trends are displayed on the home screen and calendar, making it easier to plan your schedule.
・Health Record
Outside of your period, you can record your mood, physical condition, and whether or not you have vaginal discharge. By recording premenstrual irritability, anxiety, skin problems, and breast tenderness, you can understand your own condition and take preventative measures more easily. The mood and symptom icons are based on survey results highlighting common concerns among teenage girls, allowing you to register them. Recorded physical conditions are displayed as a yearly trend, so continuing to record will help you understand your own physical rhythm.
