How to set an alarm on an iPhone

Wake up to your iPhone playing your favorite song.
December 28, 2022

You’re probably one of the many people who have replaced their old digital alarm clock with the alarm on the iPhone. There are advantages to using an iPhone alarm to wake up to. First, you can customize the sound. Second, you can customize the volume, and third, you can mirror the alarm to your Apple Watch (if you have one). If you’re just coming around to using your smartphone as your new alarm clock, here is how to set an alarm on your iPhone.

You can set an alarm on your iPhone by either using the Clock app or by asking Siri to set it for you. Siri can also switch off or cancel alarms. Make sure the alarm volume is high enough for you to hear it.


How to set an alarm on the iPhone clock app

The place you will most naturally go to to turn on the iPhone alarm is, of course, the Clock app.

  • Open the Clock app and tap the Alarm section at the bottom. Tap the + icon at the top of the screen to get started.
  • Spin the numbers around to the desired time you wish to be awoken. There are four other options you can tweak if you wish.
  • Repeat is for the alarm to go off on only certain days. Select your days, or choose every day for it to go off every day.
  • Label is for when you may need a reminder of why you have an alarm set in the first place. You can type what you need to be reminded of (soccer practice, dog walk, etc.)
  • Sound enables you to customize your alarm. Apple has various different tunes, or if you’re an Apple Music subscriber, you can select a song from Apple Music. Waking up to Eye of the Tiger is just awesome.
  • Snooze (when enabled) will stop the alarm after 60 seconds of not being turned off. It will then set a timer for another 60 seconds before going off again. It will repeat this process until you disable the alarm.

Click Save to save the alarm settings. If you decide you don’t need the alarm anymore, you can toggle it off or delete it entirely.

Set an alarm on the iPhone by asking Siri

A much simpler way of setting an alarm on your iPhone is by asking Siri to do it for you. This saves you lots of fiddling, tapping, and whatnot. Siri can get it done for you in seconds.

Siri understands virtually everything you say to her, provided you speak in a clear voice. So say something like, “Hey Siri, set an alarm for 9 am tomorrow morning” (or words to that effect). She will confirm on-screen that the alarm has been set.

To cancel the alarm, say something like, “Hey Siri, switch off my alarm for 9 am tomorrow morning.” She will then confirm on-screen that the alarm has been canceled.

When the alarm is sounding, you can ask Siri to switch it off. “Hey Siri, switch off my alarm.”

Change the alarm volume on an iPhone

Even if you have your phone in silent mode or vibrate mode only, the alarm will still sound if you have it set. But if the volume settings are way too low, you still won’t hear it. Especially if you are a very heavy sleeper.

To check that the alarm volume is high enough, go to Settings > Sounds & Haptics. Under Ringtone and Alert Volume, you can slide the volume level up and down. You can also use the buttons on the left side of your phone to also change the volume.

You can check the volume level by going to the Sounds and Haptic Patterns section, tapping Ringtone, and choosing a tone. A five-second preview of that tone will now sound, giving you a good indication of how loud it now is.

Regardless of your sound settings, any set alarms will still sound when the time comes.

Most likely because you have the volume down too low. Go to Settings > Sounds & Haptics and make sure the ringer volume is up high enough.
