You can change your iPhone alarm sound in the Clock app in about 30 seconds

Open the Clock app on your home screen, tap the Alarm tab at the bottom, then tap Edit in the upper left. Select the alarm you want to change, tap Sound, and choose a new tone from the list. The built-in options range from gentle chimes to loud beeps, and you can also use songs from your Music library. Once you pick a sound, tap Back and then Done to save the change.

If you do not see the Clock app on your home screen, swipe left through your home screen pages or use Spotlight search — swipe down from the top of the screen and type "Clock".

Key Takeaways

  • The Clock app is where you change alarm sounds, not in Settings — tap the Alarm tab, then Edit, then select your alarm and tap Sound.
  • iPhone comes with dozens of built-in alarm tones ranging from quiet to very loud, and you can preview each one before you choose.
  • You can set a song from your Music library as an alarm sound, though the alarm will start quietly and fade in over a few seconds.
  • Each alarm can have a different sound, so you can set a gentle tone for weekday mornings and a louder one for important appointments.

Finding and opening the Clock app

The Clock app comes built into every iPhone and sits on your home screen by default, though some people move it or hide it. Look for an icon that shows a clock face. If you cannot find it, swipe down from the top of your screen to open Spotlight search, type "Clock", and tap the result.

Once the Clock app opens, you will see five tabs at the bottom: World Clock, Alarm, Timer, Stopwatch, and Bedtime. Tap Alarm to see your list of alarms.

Editing an existing alarm to change its sound

In the Alarm tab, you will see all your current alarms listed with their times and days. Tap Edit in the upper left corner — the button turns blue when you are in edit mode. Now tap the alarm you want to change. A detailed screen opens showing the time, repeat days, label, and sound.

Tap the row that says Sound. A list of all available alarm tones appears with names like Alarm, Beacon, Bells, Chime, and Radar. Each tone has a speaker icon next to it. Tap the speaker icon to hear a preview of that sound before you choose it.

Choosing from built-in alarm tones

iPhone includes roughly 30 built-in alarm sounds organized by type. The quieter options like Chime, Bells, and Gentle are better if you wake easily or live with others. The louder options like Alarm, Radar, and Siren are harder to sleep through and work well if you are a heavy sleeper or need to wake for something critical.

You can preview each tone by tapping its speaker icon. The preview plays at full volume, so you get an accurate sense of how loud it will be when your alarm actually goes off. Tap the tone you want to use, then tap Back to return to the alarm details screen.

Using a song from your Music library as an alarm

Instead of a built-in tone, you can set any song you own in Apple Music or have downloaded to your iPhone as your alarm sound. At the bottom of the Sound list, you will see a section labeled Music. Tap it to see all your available songs organized by artist and album.

When you choose a song, the alarm will start playing it quietly and fade in over about 10 seconds — it will not blast at full volume immediately. This works well if you prefer waking to music you like, though the fade-in means you may not hear it right away if you are a very deep sleeper. If you do not see any songs in the Music section, you need to add music to your iPhone first through the Music app.

Saving your changes and testing the new sound

After you choose a new sound, tap Back to return to the alarm details screen. You will see the sound name now shows your selection. Tap Done in the upper right to save the change and exit edit mode. Your alarm is now set to use the new sound.

You do not need to wait until the alarm goes off to hear it again — you can tap Edit, select the alarm, tap Sound, and preview any tone whenever you want. If you change your mind, just pick a different sound and save.

Setting different sounds for different alarms

Each alarm on your iPhone can have its own unique sound. If you have a 6 a.m. weekday alarm and a 9 a.m. weekend alarm, you can set a gentle tone for the weekday one and a louder tone for the weekend one. Follow the same steps for each alarm — tap Edit, select the alarm, tap Sound, and choose.

This is useful if you want to know which alarm is going off without looking at your phone, or if you want some alarms to be easier to sleep through than others. You can also give each alarm a label (like "Work" or "Gym") so you know what it is for when it goes off.

Frequently Asked Questions

Why is my alarm not making any sound?

Check that your iPhone is not in Silent mode — look for the mute switch on the left side of the phone. If it is in the down position (toward the back of the phone), your alarm will be silent. Flip it up to turn sound back on. Also check that your volume is not turned all the way down using the volume buttons on the side.

Can I use a video or voice memo as an alarm sound?

No, only songs from your Music library and the built-in alarm tones work as alarm sounds. Voice memos and videos cannot be set as alarms. If you want to use a specific song, make sure it is in your Music app first.

What happens if I delete an alarm?

If you delete an alarm, it will not go off anymore. You can delete an alarm by tapping Edit in the Alarm tab, tapping the red minus button next to the alarm, and then tapping Delete. You can always create a new alarm later if you change your mind.

Can I change the alarm sound from the lock screen?

No, you have to open the Clock app and go through the Edit process to change a sound. You cannot edit alarms from the lock screen or from notifications. You must open the full Clock app to make changes.
