World Clock — Time Zone Widget
Whether you travel a lot or have business or family all over the world, you’ll want to keep the World Clock app near you at all times.
As you can expect from a clock app, World Clock gives you the exact time of any city or place around the world. You can track multiple times at the same time, and you can customize your clocks however you like.
Some people like to use analog or digital, while others like to use AM/PM or 24-hour time. Whatever your choice is, you can set up a clock and customize it however you want.
Moreover, you can also add the World Clock app to your iPhone’s StandBy mode, so you can easily keep track of the time of the important people in your life no matter where in the world you are.
