World Clock - Connecting Across Time Zones
This simple and easy-to-use clock app lets you check the current time around the world at a glance. It's useful for a variety of occasions, including communicating with family and friends overseas, international business meetings, and travel planning.
In today's world where we must simultaneously manage multiple time zones, this app eliminates the hassle of calculating time differences and supports communication with loved ones. Its intuitive operation makes it easy for anyone to get started.

Key Features:

📍 Register Favorite Cities
Register your frequently used cities to instantly check the time. It supports major cities around the world, and you can freely rearrange your favorites. The first city you register becomes the base point, and the time difference with other cities is automatically calculated.
You can search for cities not only by city name, but also by country name and time zone name.

⏰ Time Difference Quick Reference
Displays a list of the time differences between selected cities. Quickly answer questions like, "What time is it in New York when it's 9 a.m. in Tokyo?" or "What time is business hours in London in Japan?"
The 24-hour time zone chart lets you see the optimal time to contact someone in their city at a glance. Avoid late nights and early mornings and schedule calls at the appropriate time. This is ideal for coordinating international phone calls and video conferences.

🔔 Reminder Function
Set reminders based on the time of your international contact. Never miss an important event. For example, "Meet at 10 AM New York," and the app will display Japan time.

Set advance notifications to accommodate different time zones. You can also choose the notification timing (5 minutes, 30 minutes, 1 hour, etc.) before the event.

🌅 Automatic Daylight Saving Time Support
Automatically reflects the start and end of daylight saving time (DST) in each region. No manual adjustments are required. The app displays accurate time based on the latest time zone database.
While daylight saving time changes vary by country and region, this app automatically manages them. It even handles complex regional rules, including those in the United States, Europe, and Australia.

🔄 Sorting and Customization
You can freely rearrange your favorite cities with drag and drop. Organize them by frequency, region, or time difference—anything you like.
