How to Delete, Turn Off, or Change an Alarm on iPhone

To delete an alarm on iPhone, open the Clock app, tap Alarms, swipe left on the alarm, and tap Delete. To turn an alarm off without deleting it, tap the switch next to it. To change one, tap the alarm time, make your changes, and tap Save.

This guide covers deleting, turning off, and editing alarms, plus alarm volume, sleep schedule alarms, and alarms that won’t go away. The steps come from Apple Support’s How to set and change alarms on your iPhone article and Apple’s iPhone User Guide pages Set an alarm in Clock on iPhone and Turn off alarms and delete sleep schedules.

How to Delete an Alarm on iPhone

1. Open the Clock app.
2. Tap Alarms.
3. Swipe left on the alarm.
4. Tap Delete.

Result: The alarm is removed from the list for good. Apple lists two other ways to do it: tap Edit, tap the delete button next to the alarm, then tap Delete; or tap Edit, tap the alarm, and tap Delete Alarm.

Delete all alarms at once

The Clock app has no Delete All button. Try asking Siri something like “Delete all my alarms” and confirming when asked. It notes that with a very long list, Siri may only delete some of them on the first try, so repeat the request.

How to Turn an Alarm Off Without Deleting It

1. Open the Clock app.
2. Tap Alarms.
3. Tap the switch next to the alarm time.

Result: The alarm stays in your list, grayed out, and won’t sound until you turn the switch back on. This is the better choice for alarms you use on some days but not others.

How to Change an Alarm

1. Open the Clock app and tap Alarms.
2. Tap the alarm time, or tap Edit and then the alarm.
3. Change any of these: the time, Repeat (which days it sounds), Label, Sound (a vibration, song, or ringtone), Snooze, or Snooze Duration.
4. Tap Save.

Result: The alarm sounds with your new settings. For a vibration-only alarm, pick a vibration under Sound. Apple warns that an alarm with its sound set to None will only vibrate.

How to Change Alarm Volume

1. Open Settings and tap Sounds & Haptics.
2. Below Alarms and Timers, turn off Match Ringtone Volume and drag the slider, or leave it on to match your ringtone.
3. Turn on Change with Buttons if you want the volume buttons to adjust it.

Apple says your alarm still sounds when Silent mode or Do Not Disturb (or another Focus) is on. With headphones connected, it plays through both the iPhone speaker and the headphones.

How to Turn Off a Sleep Schedule Alarm

Wake-up alarms from a sleep schedule are set in the Health app. Apple says to turn off just the next one:

1. Open the Health app and tap Browse > Sleep > Sleep.
2. Scroll to Your Schedule and tap Edit below Next.
3. Turn off Alarm and tap Done.

Result: Only the next wake-up alarm is skipped; your normal alarm resumes afterward. To stop them all, Apple says to tap Full Schedule & Options and turn off Sleep Schedule.

Troubleshooting

• An alarm you deleted still goes off: it may be a sleep schedule alarm. Try checking the Health app’s sleep schedule first, then force restarting the iPhone if a “ghost” alarm remains.
• The alarm is too quiet or only vibrates: check the volume under Alarms and Timers and make sure the alarm’s Sound isn’t set to None, Apple says.
• The alarm went off at the wrong time: Apple says manually changing the iPhone’s time can affect alarms. Check the date, time, and time zone.
• No haptics in StandBy: Apple notes that alarm haptics are disabled in StandBy, so make sure a sound is selected.

Frequently Asked Questions

Can I recover a deleted alarm?

No. Swiping to delete removes the alarm permanently, so you’ll need to set it again. Turn alarms off instead if you might need them later.

Can Siri set or turn off alarms?

Yes. Apple says you can ask Siri something like “Set an alarm for 7 a.m.” Siri can delete alarms too.
