Overlap World Clock is a smart and intuitive world clock app designed to help you manage time across multiple time zones without confusion. Whether you work with international clients, collaborate with remote teams, or stay connected with friends and family abroad, this app removes the daily struggle of figuring out “is this today or tomorrow?” by showing global time differences in a clean, visual way.

Unlike traditional world clock apps, Overlap World Clock introduces a powerful Overlap Graph that visually highlights overlapping availability between time zones. Instead of doing mental math, you can instantly see the best meeting times between cities like London and Sydney, making scheduling calls, meetings, and catch-ups faster and stress-free. This makes it ideal for freelancers, distributed teams, and global businesses.

The app allows you to customize availability hours for each time zone, helping you define office hours, personal time, or flexible schedules. You can rename time zones for clarity (such as clients or family members), hide unused zones, and swipe through time effortlessly. With built-in calendar integration, Overlap World Clock ensures you always find a time that fits perfectly into your existing schedule.

Designed with a beautiful and minimal user interface, Overlap World Clock focuses on clarity and usability. It supports multiple time zones in one view and works seamlessly across iPhone, iPad, and Mac devices within the Apple ecosystem. The app also supports Standby Mode and widgets, making it easy to glance at global time differences while your device is charging.
