To change the alarm sound on iPhone, open the Clock app, go to the Alarms tab, tap Edit, choose your alarm, tap Sound and pick a new tone. Tap Save and you are done. The same menu is also how you change the alarm tone on iPhone for a brand new alarm, and it works on every recent iPhone. Below you will find the exact steps, the volume traps that catch people out, and what to do when the built-in list stops feeling like yours.
We make AlarmiFex, an alarm app, so we will cover the built-in way first and only then show where an app can help.
How do you change the alarm sound on iPhone?
Apple lists the steps in its guide to setting and changing alarms on iPhone. In plain words:
- Open the Clock app and tap the Alarms tab.
- Tap Edit in the upper-left corner.
- Tap the alarm you want to change.
- Tap Sound. Apple describes this row as the place to pick the sound that plays when the alarm goes off.
- Tap a tone to hear a short preview. Tap another until one feels right.
- Go back and tap Save.
That last tap matters. If you leave the screen without saving, the old sound stays. After saving, check the alarm row in the list. Your change applies to that one alarm only, so each alarm can have its own sound.
Can you pick the sound when you create an alarm?
Yes. When you tap the plus button to add an alarm, the same options appear on the screen: time, Repeat, Label, Sound and Snooze. Tap Sound before you tap Save and your choice is stored with the new alarm from the start. This saves a second trip into the edit menu.
If you would rather not tap at all, you can also ask Siri to set an alarm for you, as Apple notes in the same guide. Siri sets the time, but you will still open Clock to change the sound.
A few small habits make the setup more useful:
- Use a Label such as "Gym" or "Flight", so a different sound is tied to a different purpose.
- Pick a different sound for weekends than for work days. Your brain then reads each one as a separate signal.
- Leave Snooze on only if you really use it. It offers a few extra minutes, and for some people that becomes a habit.
Why is my alarm too loud, too quiet, or silent?
Most "my alarm sound is wrong" problems are volume or setting problems, not sound problems. Check these in order.
The alarm only vibrates
Apple points out that choosing None as the sound makes the alarm silent, so it may only vibrate. Open the alarm, tap Sound, and pick a real tone.
The silent switch and Focus
Apple states that Do Not Disturb, the Ring/Silent switch and Silent mode do not affect the alarm sound. So a muted iPhone still rings its Clock alarm. If you want to understand why some alarms still fail, our guide on alarms, silent mode and Focus goes deeper.
Alarm volume
Apple says you adjust alarm volume with the volume buttons or the slider under Settings, Sounds & Haptics, Ringtone and Alerts. You can also switch on Change with Buttons. Be careful with that switch. When it is on, turning your volume down in a video at night also turns your morning alarm down. Many people prefer to leave it off and set the slider once.
Apple also notes that with headphones connected, the alarm plays through both the iPhone speakers and the headphones at a set volume. If your alarm seems oddly loud, check whether earbuds are still in the case or paired nearby. For the opposite problem, see why your iPhone alarm is too quiet.
Can you use a song or your own sound?
The Sound screen holds Apple's built-in tones and a way to choose music as well. If a song is in your music library on the phone, you can usually pick it there. Three limits are worth knowing before you build a morning around it:
- A song from a streaming service is not always a file stored on your phone. If it is not stored locally, it may not show up as a choice.
- A long song starts at its beginning. You cannot jump to the chorus, so you may wake up to a quiet intro.
- A voice memo, a clip from a video or a recording of a friend does not appear in the built-in list at all.
We wrote a longer walkthrough on setting a song as an alarm on iPhone, and a broader comparison in ways to change your alarm sound.
Where does AlarmiFex help?
The Clock app is free, built in and reliable, and for many people it is all they need. AlarmiFex is one honest option for the cases where the built-in list is not enough. It is a free download on iPhone and Android.
- Sounds sorted by mood. AlarmiFex has 34 sounds in five moods: Calm, Energetic, Motivational, Classic and Anime. You can preview each one before you use it. Explore the mood-based sound library or browse all alarm sounds.
- Your own clip, trimmed. Import an audio file or the audio of a video, trim it to one minute or less, name it and use it on an alarm. See custom alarm sounds. AlarmiFex imports and trims. It does not record inside the app, so record a voice memo with your phone first.
- Several sounds in one morning. Wake-up Series lets you choose a time window and at least two different sounds that play across it. Read more about Wake-up Series.
- Rings on silent. On iPhone, AlarmiFex uses Apple's AlarmKit, so alarms can ring with the app closed, the phone locked or Focus on, once you allow alarms. They play at your ringer volume, so keep it turned up. Details on rings on silent.
Some sounds and custom sounds need a subscription, and the app shows current pricing and terms. To see how the two compare side by side, read AlarmiFex vs iPhone Clock. You can also see the iPhone alarm app page.
How often should you change your alarm sound?
There is no magic number. A sound you hear every day at the same minute can fade into the background, because the brain learns to skip signals that repeat without changing. If you can no longer recall what your alarm sounded like this morning, that is a good sign it is time to swap it. Our post on why your brain stops hearing the same alarm explains the idea in plain words.
A simple routine works for most people. Pick a new sound every week or two, match it to the kind of morning you want, and keep one dependable backup alarm a few minutes later. No app or tone can promise that you will wake up, so a backup is just sensible.

Quick answers
Open Clock, tap the Alarms tab, tap Edit, tap the alarm, tap Sound, choose a new one, then tap Save.
Yes. The Sound setting belongs to each alarm, so your weekday alarm and your weekend alarm can use different sounds.
Its sound is probably set to None. Open the alarm in Clock, tap Sound and choose a tone from the list.
No. Apple says the Ring/Silent switch, Silent mode and Do Not Disturb do not affect the alarm sound. Alarm volume still follows your ringer and alerts volume.
The Clock app picks from its built-in tones and music in your library. To bring in a voice memo, a clip or a trimmed song, you can use an app such as AlarmiFex, which imports audio files and video clips and lets you trim them to one minute or less.
