Your alarm used to wake you up. Now you sleep straight through it. That's not a character flaw. Your brain learned the sound and filed it under "ignore."

The fix is simple: change the alarm sound. A fresh tone, a favourite song, or a recorded voice memo can make mornings noticeably easier. Changing your ringtone does *not* change your alarms, though — the setting hides in a place most people never look.

iPhone: each alarm carries its own sound

The mistake almost everyone makes: changing one alarm's sound, then wondering why the 7:00 alarm still plays the old tone. On iPhone, every alarm stores its own sound. Change them one at a time.

  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.

Repeat for each alarm you use.

Waking up to a song

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 has to stay in your library — remove it and the alarm silently falls back to a built-in tone.

Using 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.

Three iPhone traps

Android: same idea, different menus

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.

Waking 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.

Recording 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. 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.

Pick a sound that actually wakes you up

Changing the tone is step one. Picking the right one is step two — and most people get it backwards.

When the alarm still betrays you

"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. Note the platform difference: on Android, some Do Not Disturb settings *do* silence alarms, unlike iPhone.

"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.

"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.

"The 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, leave date and time on automatic; manually changing it can affect alarms.

The fine print

Quick answers

Can I set a different alarm sound for each alarm? Yes — on both platforms each alarm stores its own sound.

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.
