This convenient feature allows you to easily reference your basal body temperature without having to take your basal body temperature.

You can track your menstrual flow (heavy/light), menstrual pain level, and whether or not you've taken medication, allowing you to review your period history. Daily trends, such as the first and second days of your period, are visible, making it easier to identify cramps and heavy periods as you record your data.

In addition, recording your period will make it easier to report your physical condition to your doctor or gynecologist based on the app's information. The period review screen allows you to see your menstrual cycle and period trends.

- Health Tracking
Outside of your period, you can track your mood, physical condition, and whether or not you have vaginal discharge. By recording symptoms like irritability and anxiety before your period, skin irritation, and breast swelling, you can better understand your condition and take preventative measures. Mood and symptom icons are based on survey results and identify concerns that teenage girls are particularly susceptible to. Recorded health data is displayed as a yearly trend, so by continuing to record, you can understand your own physical rhythm.

Health Advice
Based on the rhythm of female hormones, which are deeply connected to a girl's health, today's health advice is displayed. You can also check your "physical condition" and "mental condition" at a glance. We'll help you feel comfortable during your period.
