About this app

Good Boy is an app for men that informs you of your girlfriend's or wife's "expected condition for the day" and "how to behave" based on your period cycle.

If you want to better understand your partner and take thoughtful care of them, check out the "Good Boy Mission of the Day" and "Behavioral Tips."

***It is available for free.***

๐Ÿ’ก Key Features

1. Condition and Behavioral Guide by Cycle

โ€œMy lower back feels heavy and aches...โ€

โ€œIf the reaction to your usual teasing is different โ†’ Don't provoke them unnecessarily, just stay still.โ€

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.

๐ŸŽฏ Recommended for:

- Those who frequently argue with their partner during their expected PMS period or menstruation

- Those who want to be attentive to their partner but didn't know how

- Those who want to know their expected period date or fertile period in advance to prepare

- Those who want to better understand their partner's menstrual cycle

- Those who want to use the app conveniently without registration

โ€ป Goodboy is a reference app that calculates and provides cycle information based on the entered data; it does not provide medical diagnosis or treatment.
