💡 Key Features

1. Condition and Behavioral Guide by Cycle

“My lower back feels heavy and aches...”

“If the reaction to your usual teasing is different → Don't provoke them unnecessarily, just stay still.”

You can check the physical and mental changes that may occur according to your cycle, such as your period, fertile period, and expected PMS duration, and find behavioral tips tailored to today's situation.

2. Easy Period Calculation & Notifications

By entering your recent period start date, average cycle, and average period duration, you can check your major cycles at a glance, including your expected period date, fertile period, and expected PMS duration.

You can also receive notifications to keep track of your major cycles in advance.

** 3. Menstrual Cycle Information Stored Only on the Device

Goodboy can be used without separate registration, and menstrual cycle information and notification settings are stored only within the device.

We collect minimal app usage data to analyze service usage status and feature usage, and menstrual cycle-related information is not transmitted to external analysis services.
