How to Change Alarm Sound on iPhone

Whether the default "Radar" tone has become part of your dreams or you simply want something more pleasant to wake up to, knowing how to change alarm sound on iPhone is a basic customization that makes mornings significantly better. Apple gives you several options—built-in tones, classic sounds, and even songs from your music library—but the process is slightly different depending on whether you use a standard alarm or the Sleep/Wake Up feature.

This guide walks through every method, step by step, for iOS 26.

How to Change the Sound on a Standard Alarm

This is the most common method and works for any alarm you have set in the Clock app.

Step 1: Open the Clock App

Tap the Clock app on your home screen or find it in your App Library. It is the icon with a white clock face on a black background.

Step 2: Go to the Alarm Tab

Tap Alarm at the bottom of the screen. You will see a list of all your existing alarms.

Step 3: Select an Alarm to Edit

To edit an existing alarm, tap directly on it.

To create a new alarm with a custom sound, tap the "+" button in the top-right corner.

Step 4: Tap "Sound"

In the alarm editing screen, you will see options for Repeat, Label, and Sound. Tap Sound to open the sound selection menu.

Step 5: Choose Your Sound

You have several categories to browse:

Ringtones (Default Section)

Scroll through the list of built-in ringtones. Tap any name to preview it. These include modern options like "Radiate," "Silk," and "Constellation" as well as the classic "Radar" and "Alarm."

Classic Sounds

Scroll to the bottom of the ringtone list and tap Classic. This reveals legacy iPhone sounds that have been available since earlier iOS versions—options like "Old Phone," "Alarm," and "Bark."

Pick a Song

At the top of the sound list, tap Pick a Song to select music from your device's library.

Important note about songs: The song must be stored locally on your iPhone—meaning it was purchased through iTunes or synced from a computer. Songs streamed via an Apple Music subscription that have not been downloaded for offline use will not work as alarm sounds. This is one of the most common reasons iPhone alarms go silent unexpectedly.

Step 6: Save

After selecting your sound, tap the Back arrow (top-left), then tap Save (top-right) to apply the change.

How to Change the Sound on a Sleep/Wake Up Alarm

If you use Apple's Sleep Schedule feature (set up through the Health app or the Clock app's Sleep section), the alarm sound is managed separately from standard alarms.

Step 1: Open Clock and Go to Alarm

Open the Clock app and tap the Alarm tab.

Step 2: Find the Sleep/Wake Up Section

At the top of your alarm list, you will see a section labeled Sleep | Wake Up. Tap Change next to it.

Step 3: Tap Sounds & Haptics

In the Sleep Schedule editor, tap Sounds & Haptics. This opens a dedicated sound picker for your wake-up alarm.

Step 4: Choose a Sound

Browse the available wake-up sounds. These are specifically designed by Apple to be gentler and more gradual than standard ringtones—they fade in slowly to ease you out of sleep.

Step 5: Save Your Changes

Tap the Back button, then tap Done to save.

Test the Volume

Your alarm uses the Ringer and Alerts volume, not your media volume. Go to Settings > Sounds & Haptics and make sure the Ringtone and Alert Volume slider is turned up.

Toggle off "Change with Buttons" if you want to prevent accidental volume drops when you adjust your media volume.

Troubleshooting: Alarm Sound Not Playing

If your alarm goes off silently or too quietly, check these common issues:

Attention Aware Features (on iPhones with Face ID) can lower the alarm volume if the phone detects you are looking at it. We have a detailed guide on [fixing quiet iPhone alarms here](/blog/why-is-my-alarm-so-quiet-iphone).

Music Library songs that are only streaming (not downloaded) will fail silently. Switch to a built-in ringtone.

Bluetooth connected to headphones or speakers may route alarm audio to the wrong device. Disconnect Bluetooth before bed.

Do Not Disturb and Focus modes do not block alarms, but verify your specific Focus settings to make sure.

Want an Alarm That Actually Gets You Out of Bed?

Changing your iPhone alarm sound helps, but if you are a heavy sleeper, a pleasant melody is not enough. FixSleep goes beyond sounds with mission-based alarms that require you to solve a math problem, scan a QR code, or shake your phone before the alarm stops. You cannot sleepwalk through it.
