The stock alarm tone gets old fast — and once your brain learns to sleep through it, it stops working. Changing your alarm sound is one of the quickest phone upgrades you can make: a fresh tone, your favourite song, or even a recorded voice memo can make mornings noticeably easier. This guide covers changing the alarm sound on iPhone and Android, with exact menus, custom-audio options, and fixes for the most common problems.

Change the alarm sound on iPhone

On the iPhone, each alarm carries its own sound. Changing the default ringtone does not change your alarms — you edit the sound inside the alarm itself.

  1. Open the **Clock** app and tap the **Alarm** tab at the bottom.
  2. Tap **Edit** in the top-left corner, then tap the alarm you want to change — or tap **+** to create a new one.
  3. Tap **Sound** to open the sound picker.
  4. Tap any built-in tone to hear a preview, then tap your favourite.
  5. Tap **Back**, then tap **Save** in the top-right corner.

Your new sound applies to that alarm only. If you have several alarms, repeat the steps for each — a common mistake is changing one and wondering why the 7:00 alarm still plays the old tone.

Use a song as your iPhone alarm

If you have Apple Music, any song in your library can be an alarm:

  1. Open Apple Music and add the song to your library (the **+** button).
  2. Go back to **Clock → Alarms → Edit → your alarm → Sound**.
  3. Tap **Pick a Song** and choose it, then tap **Save**.

The song must stay in your library — if you remove it, the alarm falls back to a built-in tone.

Use your own audio file

On recent iOS versions you can turn a short audio file into a tone straight from the Files app: save the audio in **Files** (under 30 seconds works best), long-press it, tap **Share → Use as Ringtone**, trim it if asked, then pick it in **Clock → Alarms → Sound**. Apple documents the official alarm workflow — creating, editing and deleting alarms — on its How to set and change alarms on your iPhone support page.

iPhone alarm gotchas

Change the alarm sound on Android

The exact screens depend on your phone brand, but most Android phones use the Google Clock app or the Samsung clock app with the same basic flow.

Google Clock app (Pixel and many others)

  1. Open the **Clock** app and tap **Alarm** at the bottom.
  2. Tap the **down arrow** on an existing alarm to expand it (or tap **+** to add one).
  3. Tap the **bell icon** next to the current alarm sound.
  4. Browse the built-in sounds and tap one to preview and select it.

Wake up to a song on Android

The Google Clock app can pull music from installed services:

  1. Install and sign in to **Spotify**, **YouTube Music** or **Pandora**.
  2. In the Clock app, expand the alarm and tap the bell icon.
  3. Switch to the **Spotify / YouTube Music / Pandora** tab in the sound picker.
  4. Search for a song, album or playlist and tap it to set it as the alarm.

Picking specific songs usually needs a premium subscription on these services; free tiers typically limit you to playlists. See the service breakdown in SlashGear's guide to changing the alarm sound on Android.

Record your own alarm sound (Pixel)

On Pixel phones, the Google Clock app can record a custom alarm sound on the spot — a voice memo, a kid's voice, a spoken reminder:

  1. Open Clock → Alarm, expand an alarm and tap the **bell icon**.
  2. Tap **Record new** under Recorded sounds.
  3. Record your sound, then tap **Save** — it becomes that alarm's sound immediately.

The recording flow is documented in Android Central's guide to custom alarm sounds.

Samsung phones

Open **Clock → Alarm**, tap the alarm time, then tap **Alarm sound**. Samsung offers its own sound set, and on some models you can add downloaded audio by placing an MP3 in the phone's **Alarms** storage folder so it appears in the picker.

Troubleshooting

The alarm plays but I can't hear it

On iPhone, check **Settings → Sounds & Haptics → Ringtone and Alerts** — that slider is the alarm volume. On Android, alarms usually have their own slider under **Settings → Sound & vibration → Alarm volume**. On Android, some Do Not Disturb settings do silence alarms (unlike iPhone) — check DND's alarm exception.

I changed the sound but the old one still plays

You probably edited the wrong alarm — each alarm stores its own sound. Also check whether the firing alarm is a **Sleep schedule** or **Bedtime** alarm, which carries separate settings on both platforms.

My custom song stopped working

On iPhone, if the Apple Music song left your library or isn't downloaded, the alarm reverts to a built-in tone. On Android, a music-service alarm needs an internet connection unless the track is downloaded for offline use. For critical wake-ups, prefer a downloaded audio file or a built-in tone.

Alarm never fires at all

On Android, battery-optimization settings can kill clock apps — exclude your clock app from battery optimization, and verify the time and AM/PM are right. On iPhone, Apple's official guidance warns against manually changing the date and time, which can affect alarms — leave it on automatic.

Limitations to know

FAQs

**Can I set a different alarm sound for each alarm?**
Yes — on both platforms each alarm stores its own sound, so set them independently.

**Can I use a video's audio as an alarm?**
Only after extracting the audio to an MP3 or AAC file. Alarm pickers can't pick sound from a video file directly.

**Do alarms work when the phone is off?**
No — the phone must be on. Alarms do fire in silent and Do Not Disturb mode on iPhone; on Android check your DND alarm settings.

**Will the alarm play through headphones?**
Apple confirms the alarm plays through the phone's built-in speakers as well as connected headphones, so you'll hear it either way.
