You can show up to 8 time zones on a single large widget, so everything you need is one glance away. Can I use custom labels instead of city names? Yes. You can name any clock whatever makes sense to you. “Mum in Sydney” tells you at a glance whether it’s safe to call. “Dev team in Berlin” tells you whether they’re in the office. Your clocks, your labels. Does it work on Apple Watch? Yes. There’s a dedicated Apple Watch app plus support for multiple complications, so your world clocks are always on your wrist.

World Time Widget works across iPhone, iPad, and Apple Watch. Your clocks sync across all your devices via iCloud. What makes it different from Apple’s Clock app? Apple’s Clock app is useful, but limited. World Time Widget adds a day/night indicator for every clock so you can see at a glance who’s awake, lets you use personal labels instead of city names, and puts your world clocks on your home screen, lock screen, StandBy, and Apple Watch with far more flexibility. Apple Clock also caps out at 4 cities in a widget. World Time Widget shows up to 8. Is there a free version? World Time Widget is free to download with a premium upgrade available for additional features.

Find the perfect time to catchup across multiple time zones without the mind-bending math. Overlap is a smart world clock that helps you connect with people in different time zones. It makes it simple to see the time in multiple places at once, and its fun Overlap Graph is a unique visual way to quickly find convenient meeting times across the world. You can choose ‘available’ hours for each time zone. For example Dan in London might be available from 2pm to 5pm and Rashida in Sydney might be available from 7am to midday. Bring up the Overlap Graph and it will magically show you the most compatible times to schedule your catchup. Overlap also displays your calendar events, so you can always find a time that suits your schedule. Available on iPhone, iPad and Mac. • You can see multiple time zones in one beautiful UI • You can swipe left and right to quickly move through time. • You can customize 'availability' for each timezone - this could mean office hours for a meeting or simply when you're available for a group chat with your far-flung family -no more 'Sorry that's 3am for me!' • You can rename each time zone; for example, you might simply rename a time zone to say 'Grandma' or the name of a client you work with. Or perhaps your Grandma is your client, no judgement here. • You can hide time zones that you don’t need right now so it’s always easy to focus on what you need to know. • You can show your calendar events so you can always choose a time that fits your schedule. • Once you’ve chosen a great time its easy to share it via your favorite messaging app or create a calendar event. • Standby Mode is a Lock Screen feature that activates automatically when your iPhone is charging in landscape mode. The Overlap widget fully supports this mode!
