This wikiHow teaches you how to set different types of alarms on your iPhone, with a focus on using the Clock app and Siri as voice assistant options. If you recently upgraded to iOS14, you can find the Bedtime feature in the Health app under Sleep Schedule settings.

Before you start: Ensure your iPhone is updated to the latest iOS version and that Siri is enabled on your device.

Warning: Double-check your alarms to ensure they are set correctly and that your device’s battery is charged, as alarms will not sound if the battery is dead or the device is turned off.

How to set alarms on your iPhone

Follow these steps to create and manage alarms on your iPhone using both the Clock app and Siri.

  • Open the Clock app on your iPhone. It’ll be on one of your home screens and/or in the Utilities section of the App Library.
  • Tap the Alarm tab. It’s the alarm clock icon at the bottom of the screen.
  • Tap +. It’s the plus icon at the top-right corner.
  • If you want to edit an existing alarm instead, tap Edit at the top-left corner, and then tap the alarm below.
  • Tap the orange alarm time. It’s in the square next to “Time.” This highlights the hour while leaving the minutes grayed-out.
  • Use the keypad to enter the hour. For example, if you’re going to set the alarm for 3:30, enter 3.
  • Tap the orange alarm time again. This time, the minutes will highlight in orange.
  • Use the keypad to enter the minutes. For example, for a 3:30 alarm, you’d enter 30 here.
  • Tap AM or PM. It’s next to the alarm time. If your iPhone uses 24-hour time, you won’t have this option.
  • Customize your alarm’s other settings:
    • Tap Repeat to choose each day on which you want your alarm to go off. If you prefer it to only go off on purpose, skip this step.
    • Tap Label to assign a name to your alarm. You can use this when interacting with Siri—for example, if you set an alarm called “Work,” you could say, “Hey Siri, set my Work alarm.”
    • Tap Sound to select a sound from the list of stock ringtones or pick a song from your library to play when the alarm goes off.
    • Slide the Snooze option to enable (it will turn green) or disable (it will turn white) snooze. You can snooze by tapping the “Snooze” button on the lock screen when your alarm goes off.
  • Tap Save. It’s at the top-right corner of the screen, saving your new alarm and enabling it immediately.
  • You can turn an alarm on or off by sliding the switch on the right side of its tab right or left respectively.
  • To add additional alarms at any time, tap + at the top-right corner.

Using Siri to set alarms

  • Enable Siri on your iPhone if you haven’t already. Check out How to Set Up Siri to get started.
  • Summon Siri with your voice or a button. If Siri is set up to listen for “Hey Siri,” say “Hey Siri” to summon her now. Alternatively, press-and-hold the Home button or the side button to activate Siri.
  • Say, “Set an alarm for time.” Replace time with the time you want the alarm to sound. You can also specify days, a specific date, or recurring days.
  • Manage your alarms with Siri. You can ask questions like “What alarms do I have set?” or use commands like “Disable all alarms” or “Change my Work alarm to 7:20.”

Setting up bedtime alarms in the Health app

  • Open the Health app. The Bedtime feature is now in the Health app, represented by a white icon with a pink heart.
  • Tap Browse. It’s the four squares at the bottom-right corner of the screen.
  • Scroll down and tap Sleep. It’s the green bed icon.
  • Scroll down and tap Get Started. If already set up, you can edit existing sleep schedules.
  • Tap the days you want to include in your schedule in the “Days Active” section.
  • Set your Bedtime and Wake Up times using the drag icons.
  • Customize the sound and volume of your alarm at the bottom.
  • Tap Add to save your changes, followed by Next.
  • Tap Enable Sleep Mode to turn it on or tap Skip if you want to set it later.
  • Tap Enable Wind Down for Do Not Disturb mode before bed, or tap Skip to continue without it.
  • Tap Done to save your sleep schedule.

Pro tip: Make sure your volume button and sound effects are fully turned up to ensure the alarm is loud enough to wake you up.

Setting alarms on your iPhone is a simple and effective way to help manage your time and ensure you stay on schedule.

Frequent users will benefit from exploring the new Sleep Schedule features in the Health app, which can bring added functionality to your daily routine.
