CalZones is a calendaring app built from the ground up to be savvy about managing timezones. It starts by letting you choose a list of the zones that are relevant to you and then all aspects of the app tailor themselves to making it easy to coordinate between those timezones.
The main timeline view shows you a comparison of the time in each of your locations for quick reference. Below this timeline your events are laid out to give you an easy glanceable view of your upcoming events. Tap on any time shown to quickly create an event at the shown time and in the selected timezone.
The calendar view provides a more traditional view to explore your events with. You can quickly jump to a particular day and see the events scheduled. Each event is expandable to see when the event is in each timezone, perfect for coordinating a meeting or call.
The event creation view makes working out the time for a call super easy by giving you a time picker that is timezone aware and displays the chosen time across all your selected timezones.
The Today Widget for CalZones provides two distinct modes. The compact view is a quick timezone converter utility, showing you the current time/date in your selected timezones. The expanded view provides the full functionality of the timeline right from your widget screen. you can browse your day's events or tap to create or edit events.
On the Apple Watch Calzones provides a rich timezone conversion tool. Turn the Digital Crown to compare the time in your selected places. Then once you find the time you are looking for you can tap any of the locations to quickly create an event at the time shown, right from your Apple Watch! Swipe to the right to see a list of your upcoming events all shown in one place. (Requires an Apple Watch)
CalZones also includes a comprehensive set of beautiful Apple Watch Complications. These include showing the current time, the daylight hours, the workday, or a classic Sun & Moon display. You can completely customize which location is shown with which display from the interactive configuration screen in your iPhone app. (Requires an Apple Watch)
I hope you enjoy using CalZones and find it useful.
Quick bugfix update to fix an issue where tapping the "Configure Complications" button in settings could cause the app to freeze.

Indispensable for global jobs
My job has me supporting team members, suppliers, and customers located around the world. Obviously scheduling meetings are even making phone calls becomes a logistical challenge. Is it to late? Is it to early? It gets worse when I’m traveling internationally and I need to coordinate from a different base time zone.
CalZones instantly became indispensable for my job. I HIGHLY recommend it to everyone who has even occasional needs to coordinate across time zones. Whether is core to your job like me or you have family, friends, or yourself traveling across time zones on holiday, CalZone is the perfect tool to simplify managing and coordinating across time zones.
When I first started hearing this idea described various places a few months ago, I’ll admit I was a skeptic, but the moment I scrolled through my events on this app for the first time, I just got it.
This may not replace Fantastical on your phone. That’s fine! It’s not for that. But sometimes we have things in life we need to plan for a lot of people in a lot of places, and I’m not sure anything has ever assisted with that this well before.
Best in class
Smooth, beautiful, useful. None of these are words that I ever thought would describe a time zone app. But David Smith has done it again! I have family and friends spread out across several countries and this app makes checking when to contact them a breeze.
David also sweated the small details. Switching between calendar and time zone view is smooth and visually appealing. Also, different shades on times appear depending on the time of day in that time zone.
He is also really responsive to feedback, adding more cities within a week or so of my request.
If you have family, colleagues, or friends abroad, just buy this app.
With Family Sharing set up, up to six family members can use this app.
