When you ask Siri to “set an alarm,” it creates a new alarm each time. After a while, your iPhone alarm clock can get messy with scores of alarms you’re no longer using.
The Clock app lets you cancel and delete alarms one-by-one. However, if you have a lot of alarms, canceling and deleting them individually may not be a good solution.
The easiest, and to my knowledge, only way to cancel or delete all of your alarms at once on an iPhone is to use Siri.
How to cancel all alarms
Siri can quickly cancel all your alarms without deleting them if you have several alarms enabled. By cancelling, we mean turning off your active alarms. Here is how:
- Hold down your iPhone’s home or Side button.
- Tell Siri: "cancel all my alarms" or “turn off all my alarms”. Siri will respond by saying “I turned off all of your alarms”.
- And all of your active alarms will be turned off.
By the way, Siri can also turn on all your alarms at once. Just say "Hey Siri, turn on all my alarms" or "Hey Siri, enable all my alarms."
How to delete all alarms
Siri can also quickly delete all your alarms. This will remove all your active and inactive alarms. All of your alarms will be gone. Here is how:
- Hold down your iPhone’s home or Side button.
- Tell Siri: "Delete all my alarms" or “remove all my alarms.”
- Siri will ask you to confirm the request by saying “Do you want to delete all your alarms? Say "Yes" or tap the "Yes" button. And Siri will confirm by saying “I deleted all of your alarms.”
