Maybe you're an instructional designer working with subject matter experts based in multiple states. Maybe you need to schedule new product training webinars for sales teams around the world. Or perhaps you're thinking about taking remote work to the next level and becoming a digital nomad. Whatever the reason, there's a good chance that sometime soon you will need to schedule a meeting with people in different time zones.

World Time Buddy is a free productivity tool, available for both iOS and Android devices, that lets you compare multiple time zones at a single glance. After downloading the app and setting up your primary location, you can add more locations easily by typing in the name of a city or country. The app likewise enables you to reorder, group, and rename locations according to your personal business needs.

The default setting in the app's scheduling feature provides a 30-minute window for an event or meeting, but you can change that by clicking and dragging over available time slots. Once you've scheduled the event, you can overlay your Google calendar, Outlook, or iCal, and the app will create a custom URL that you can share publicly.
