Many iPhone owners use their phone as their sole alarm—you might not even own a real alarm clock anymore. And while this is a useful function of the app, you may not realize that the Clock app does a lot more than just wake you up.

In case you haven't explored it, let's take a look at what your iPhone's Clock app can do and why you probably don't need to replace it.

Using Alarms on Your iPhone

If you don't need to resort to drastic measures like evil alarm apps to get up in the morning, the Alarm function of your iPhone should more than suffice. Setting an alarm is a simple matter of opening the Clock app and tapping the Alarm tab at the bottom.

Tap the Plus button in the upper-right corner to add an alarm. To edit an existing alarm, tap the Edit button in the upper-left corner of the Alarm screen and then tap the alarm you want to adjust. Either way, you'll see the same alarm editing screen.

First, tap the box in the Time field and use the keypad to enter the time you want to wake up. By default, iPhone alarms are one-time events. Whenever your alarm sounds and you turn it off, you have to turn it back on the next time you want to use it. If you use the Repeat option, you can have it sound automatically on certain days.

Labels let you differentiate your alarms from one another. They aren't necessary, but they can make it easy to tell them apart in the list. Labels also show when the alarm goes off, which helps you remember what you set it for if you use them for purposes other than getting u.

Don't forget to decide which alarm Sound you want to wake you from your slumber. In addition to the default alarm tones and other ringtones on your iPhone, you can pick from music on your device. This menu also lets you customize the Vibration for the alarm.

Lastly, to avoid temptation, you can disable the Snooze button.

To delete an alarm, just swipe left on its entry and tap the resulting Delete button. You can also hit the red Delete icon that appears on the left side while on the Edit screen. Your alarms will be automatically arranged from earliest to latest.

Sleep: A More Refined Alarm

Older versions of iOS had a feature called Bedtime inside the Clock app. Apple has since renamed this to Sleep and moved it to the Health app. On the Alarm tab, you'll see a prompt to use your alarms from this feature, or set it up if you haven't already.

With Sleep, you can set up a schedule to get enough sleep for your needs. Your iPhone will then help you to stay on track by setting an alarm automatically, helping you wind down when it's time to go to bed, and similar. To get started, open the Health app on your iPhone, tap the Browse tab at the bottom, and chose Sleep from the list.

From there, follow our guide to using the sleep tracking features on your iPhone to master using them.

Other Useful Clock Features

The Clock app isn't just about alarms and getting better sleep. It boasts three other notable features, assuring you won't have to visit the App Store for anything else clock-related. Skip the apps loaded with ads and just use the built-in solutions below.

Time Everything With Stopwatch

Dedicated stopwatch apps are plentiful and unnecessary, since your iPhone already has one built-in. If all you're doing is timing a speech or running laps around the track, it should be more than enough.

This mode is easily accessible from the Stopwatch tab at the bottom of the Clock app. Your iPhone's stopwatch features a digital and analog mode; swipe left or right on the stopwatch face to switch between the two.

Its operation is as simple as you would expect a stopwatch to be (with Start, Stop, and Reset buttons). It can also track lap times, and will note your fastest lap in green and slowest in red.

Use the Timer to Count Down

Just as the stopwatch lets you count time up, the timer is for counting down. This lets you know when your break is over, the moment you've steeped the perfect cup of tea, or when to take something out of the oven.

To set a timer, tap on the Timer tab in the Clock app. Spin the dials to set how long you want your timer to run in hours, minutes, and seconds. Then use When Timer Ends to pick a sound, and press Start when ready. In addition to your timer counting down, you'll see the time when your timer is set to expire in the middle of the circle.

To stop your timer prematurely, tap Pause. You can later Resume, or Cancel if needed.

World Clock: What Time Is It Anywhere?

The final feature of the Clock app is handy if you work with a remote team or are simply curious about our world. The world clock function lets you see the time anywhere on Earth. So when you need to know if it's a good meeting time in Croatia, or if people are sleeping in Calcutta, all you need to do is open Clock and tap on World Clock.

For each clock, you'll see the local time, as well as its offset from your current time zone.

Adding clocks is as easy as tapping the Plus in the upper-right corner, then scrolling to or searching for a location. We recommend adding UTC as a standard if you're a time enthusiast. Tap Edit to delete and reorder the clocks.

All Your Clock Needs Fulfilled With iPhone

The Clock app on your iPhone is more than capable of fulfilling your most essential time needs. Whether you need alarms, a world clock, or a way to time activities, it's got you covered.

If you want further functionality in some area, there are of course apps that fill certain niches. But for a balance of simplicity and features, you really don't need anything else. The iPhone's Clock already does it all, and it's free with no ads or in-app purchases nonsense.
