To delete an alarm on an iPhone, open the Clock app, tap Alarms, then swipe left on the alarm and tap Delete. You can also tap Edit, tap the red minus button next to an alarm, and tap Delete. To clear every alarm at once, ask Siri to “Delete all my alarms.”
The Sleep | Wake Up alarm at the top of the list is different: it’s part of your Sleep schedule and is turned off or removed in the Health app.
Quick Answer
Clock > Alarms > swipe left on the alarm > Delete.
Delete One Alarm
- Open the Clock app.
- Tap Alarms at the bottom.
- Swipe left on the alarm you want to remove.
- Tap Delete.
Other ways: Tap Edit, tap the red minus next to the alarm, then Delete. Or tap Edit, tap the alarm itself, and choose Delete Alarm at the bottom.
Delete All Alarms at Once
The Clock app doesn’t have a “delete all” button. Say or type to Siri: “Delete all my alarms.” Siri asks you to confirm, then removes your alarms. The Sleep schedule alarm is managed separately in the Health app.
Turn Off vs. Delete
| Action | What happens | Best for |
|---|---|---|
| Turn the switch off | Alarm stays saved but won’t ring | Alarms you use now and then |
| Delete | Alarm is removed | Alarms you’ll never use again |
| Skip for Tonight (Sleep alarm) | Skips one wake-up | Days off |
Remove the Sleep | Wake Up Alarm
- In Clock > Alarms, tap Change next to Sleep | Wake Up (this opens Health).
- To stop only the alarm, turn off Wake Up Alarm for that schedule.
- To remove the whole schedule, open Health > Browse > Sleep > Full Schedule & Options, tap the schedule, and tap Delete Schedule.
Troubleshooting
- No Delete button when swiping: Swipe farther left, or use Edit instead.
- A deleted alarm still rings: It may be a Sleep schedule alarm, or an alarm set by another app or an Apple Watch. Check the Health app and the other app’s settings.
- Alarms come back: An iCloud or device restore can bring them back. Delete them again after the restore finishes.
Apple’s guide to setting and changing alarms on iPhone covers editing alarm times, labels, and sounds.
