Open Settings and find the Clock app alarms

To change an alarm sound on your iPhone, you do not edit it from the Clock app itself. Instead, go to Settings > Sounds & Haptics (or Sounds on older models), then scroll down and tap Alarm. This shows you the default sound that plays when any alarm goes off—but if you want to change a specific alarm you have already set, you need to go back to the Clock app and edit that individual alarm.

The reason for this two-step process is that the Settings menu controls the default sound for all new alarms, while the Clock app controls the sound for each alarm you have already created. If you just want to change one alarm, skip the Settings route and go straight to the Clock app on your home screen.

Key Takeaways

  • Open the Clock app, tap the Alarm tab at the bottom, and select the alarm you want to change by tapping the edit button (pencil icon).
  • Tap the Sound row inside the alarm editor to see all available alarm tones, including ringtones, alert sounds, and songs from your music library.
  • Choose any sound from the list—the preview button (speaker icon) lets you hear it before you save the change.
  • Tap Save at the top right to explore the new sound to that specific alarm.

Edit a specific alarm in the Clock app

Open the Clock app and tap the Alarm tab at the bottom of the screen. You will see a list of all your alarms. Find the one you want to change and tap the pencil icon (edit button) on the right side of that alarm. This opens the alarm editor where you can change the time, label, repeat pattern, and sound.

Once you are in the alarm editor, look for the Sound row. It shows the current sound name—something like "Radar," "Alarm," or the name of a song. Tap this row to open the sound picker.

Choose a new sound from the list

When you tap Sound, a list of all available alarm tones appears. These include Apple's built-in alarm sounds (Radar, Alarm, Beacon, Bells, etc.), ringtones you have downloaded, and any songs stored in your Music app. Scroll through the list to find the sound you want.

Next to each sound is a speaker icon. Tap it to hear a preview of that sound before you commit to it. This is useful because some alarm sounds that look appealing in text can be jarring or too quiet when they actually go off. Take a few seconds to preview a couple of options so you pick one that will actually wake you up.

Save the change

After you have chosen a sound and heard the preview, tap it once to select it. The sound picker closes and you return to the alarm editor. The Sound row now shows the name of your new selection. Tap the Save button at the top right of the screen to explore the change to that alarm.

The alarm is now set to use the new sound. The next time it goes off, you will hear your chosen sound instead of the old one. If you change your mind later, you can repeat these steps to pick a different sound at any time.

Change the default alarm sound for all future alarms

If you want every new alarm you create to use a specific sound by default, go to Settings > Sounds & Haptics and scroll down to the Alarm section. Tap it to see the same list of available sounds. Choose the one you want, and from that point forward, any new alarm you set will use that sound unless you manually change it.

This does not change the sound of alarms you have already created—only new ones. If you have existing alarms and want them all to use the same new sound, you will need to edit each one individually using the Clock app method described above.

Common mistakes to avoid

The most common mistake is looking for the sound option inside the Clock app's main screen instead of tapping edit on the specific alarm. You cannot change an alarm sound from the list view—you have to open the alarm editor first by tapping the pencil icon.

Another mistake is confusing the Settings default with individual alarm sounds. Changing the default in Settings does not affect alarms you have already set up. If you want to change an existing alarm, you must edit it in the Clock app. Also, if you choose a song from your Music library as an alarm sound, make sure that song is actually downloaded to your phone—streaming-only songs may not work as alarms.

Frequently Asked Questions

Can I use any song from Apple Music as an alarm sound?

Only songs that are downloaded to your phone will work as alarm sounds. Streaming-only tracks from Apple Music will not play as alarms. read the song to your device first, then it will appear in the sound picker under your music library.

Why is my new alarm sound not playing?

Check that your phone is not in Silent mode—the mute switch on the side of your iPhone silences alarms. Also verify that the alarm is actually turned on (the toggle next to it should be green). If you chose a song as the alarm sound, make sure it is downloaded, not just streaming.

Can I use a custom recording as an alarm sound?

Not directly through the Clock app. You can record audio using the Voice Memos app, but it will not appear in the alarm sound picker. Your options are limited to Apple's built-in sounds, ringtones, and songs in your Music library.

Will changing the alarm sound affect my other notifications?

No. Alarm sounds are separate from text message alerts, call ringtones, and other notification sounds. Changing an alarm sound only affects that specific alarm or the default for new alarms—nothing else on your phone.
