Clock

You can see the local time in time zones around the world. In the Clock app on your iPhone, World Clock lets you manage your list of cities, so you can add a city, delete a city, or reorder the cities whenever it’s useful.

Siri: Ask Siri something like: “What time is it?” or “What time is it in London?”

1. Start the Clock app on your iPhone.
2. Tap World Clock.
3. To manage your list of cities, do any of the following:
   • Add a city: Tap the Add button and choose a city.
   • Delete a city: Swipe left on the city. Then tap the Trash button.
   • Reorder the cities: Tap Edit, then drag the Reorder button up or down.

     When you’re finished, tap the Done button.

In the Clock app, you can use the stopwatch to measure the duration of an event. It keeps timing even when you open another app or iPhone goes to sleep, and you can record laps or splits. You can also switch between digital and analog stopwatch faces in portrait orientation.

1. Open the Clock app on your iPhone.
2. Tap Stopwatch.

   To switch between the digital and analog faces, swipe the stopwatch.

3. Tap Start.

   The timing continues even if you open another app or if iPhone goes to sleep.

You can make changes to your wake up alarm if you’ve set up a sleep schedule in the Health app.

You can change just your wake up time, or shift your whole sleep schedule, so your bedtime and wake up time move together and your sleep duration stays the same. In Alarm Options, you can also choose a vibration or ringtone, set the alarm volume, and turn on Snooze to see a Snooze button with your alarm.
