Open Settings and find the Clock app alarms

To change an alarm sound on your iPhone, start by opening the Settings app from your home screen. Scroll down and tap Sounds & Haptics (on newer iPhones) or Sounds (on older models). This is where iPhone stores sound settings for notifications, ringtones, and alarms.

However, the alarm sound itself lives in the Clock app, not in Settings. Open the Clock app—it's the one with a clock face icon—and tap the Alarms tab at the bottom of the screen. Find the alarm you want to change and tap the Edit button in the top left corner.

Key Takeaways

  • Alarm sounds are changed in the Clock app, not in the main Settings app, even though other notification sounds are in Settings.
  • Tap Edit next to the alarm you want to change, then tap Sound to see all available alarm tones.
  • iPhone comes with about 30 built-in alarm sounds, and you can also use songs from your Music library as alarms.
  • If you want a song as your alarm, make sure it is downloaded to your phone, not just saved in a playlist.
  • Changes save automatically when you tap back or swipe to return to the alarm list.

Tap Sound and choose from built-in tones or your music

Once you are in the Edit screen for your alarm, look for the Sound row. Tap it to open a list of available alarm sounds. iPhone includes roughly 30 built-in alarm tones with names like Alarm, Beacon, Bells, Chime, and Radar. Scroll through the list and tap any sound to hear a preview—it will play for a few seconds so you can decide if you like it.

Below the built-in tones, you will see a Sounds section that shows songs from your Music library. If you have downloaded songs to your phone (not just added them to a playlist), they appear here. Tap any song to use it as your alarm. Downloaded songs work better than streamed ones because they will play even if you lose internet connection.

Confirm your choice and test the alarm

After you select a sound or song, tap the back arrow or swipe left to return to the Edit screen. Your new sound is now set for that alarm. Tap the back arrow again to return to the Alarms list, and your change saves automatically—you do not need to tap a Save button.

To make sure the alarm will actually wake you, test it by setting a second alarm for two minutes from now and leaving your phone on the table while you step away. This is the only way to hear how loud the sound will be in real conditions. Many people find built-in tones like Alarm or Beacon louder and more reliable than songs, especially if your phone is across the room.

Why some sounds may not appear in your list

If you have a song in your Music app but it does not show up in the alarm sound list, the most common reason is that it is not downloaded to your phone. Streaming services like Apple Music and Spotify let you save songs to your library, but the alarm app only recognizes songs that are actually stored on your device. To read a song, open Music, find the song, tap the cloud icon with a down arrow, and wait for it to finish downloading.

Another reason a song might not appear is if it is a video file or in a format your iPhone does not support. Alarm sounds must be audio files in a format like MP3 or AAC. If you have added a song through a third-party app or email, it may not be in your Music library at all, and you will need to add it through the Music app first.

Setting different sounds for different alarms

Each alarm on your phone can have its own sound. If you have a 6 a.m. alarm for work and a 9 a.m. alarm for weekends, you can set them to different tones so you know which one is going off without opening your eyes. Follow the same steps—tap Edit, tap Sound, choose a different tone, and save. This is useful if you want a gentle sound for a weekend alarm and a loud, jarring tone for an alarm you absolutely cannot sleep through.

You can also change the label of each alarm to help you remember what it is for. In the Edit screen, tap the label field at the top (where it says "Alarm" or whatever you named it) and type something like "Work" or "Gym". The label appears on your lock screen when the alarm goes off, so a clear name helps you decide whether to snooze or get up.

Troubleshooting when your alarm does not make sound

If your alarm goes off but makes no sound, the first thing to check is your phone's Ring/Silent switch—the small toggle on the left side of your iPhone. When the switch is flipped toward the back of the phone (so you see orange or red), your phone is in silent mode and alarms will not make sound. Flip it forward so the orange or red disappears, and your alarms will ring at full volume.

If the switch is already in the correct position and you still hear nothing, open the Clock app and check that your alarm is actually turned on—the toggle next to the alarm should be green. You can also try changing the alarm sound to a different built-in tone and testing it again. If a built-in tone works but your custom song does not, the song file may be corrupted or in an unsupported format.

Frequently Asked Questions

Can I use a song from Spotify or Apple Music as my alarm?

Only if the song is downloaded to your phone. Streaming services let you read songs for offline listening, but you must do this before setting the alarm. Open the app, find the song, and tap the read button. Once downloaded, it will appear in your alarm sound list.

Why does my alarm sound different on my phone than it did in the preview?

The preview plays through your phone's speaker at a moderate volume. When the alarm actually goes off, it plays at maximum volume and may sound louder or different depending on where your phone is and what is around it. Test your alarm by setting it for a few minutes from now and stepping away to hear the real volume.

Can I set a different alarm sound for weekdays and weekends?

You need to create two separate alarms—one for weekdays and one for weekends. In the Edit screen, tap Repeat and choose which days the alarm should ring. Then set each alarm to a different sound. This way you can have a loud tone for work days and a gentler one for mornings off.

What happens to my alarm sound if I delete a song from my Music library?

If you delete a song that is set as an alarm sound, the alarm will still go off but will use the default Alarm tone instead. To avoid this, keep any songs you use as alarms in your Music library, or switch the alarm back to a built-in tone before deleting the song.

Does my alarm work if my phone is turned off?

No. Your iPhone must be powered on and not in airplane mode for the alarm to ring. The alarm will not wake your phone from a powered-off state. Make sure your phone has enough battery and is turned on before you go to sleep.
