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!
