How to set and manage alarms on your iPhone

Learn how to set and edit an alarm, ask Siri to set alarms for you, and track your bedtime.

With the Clock app, you can turn your iPhone into an alarm clock. Just open the Clock app from the Home screen or Control Center. You can also ask Siri to set an alarm for you.

 

     

Set an alarm

  1. Open the Clock app, then tap the Alarm tab.
  2. Tap .
  3. Set a time for the alarm. You can also choose one of these options:
    • Repeat: Tap to set up a reoccurring alarm.
    • Label: Tap to name your alarm.
    • Sound: Tap to pick a sound that plays when the alarm sounds.
    • Snooze: Turn on to see a Snooze option when the alarm sounds.
  4. Tap Save.

Set the alarm's volume

Tap Settings > Sounds & Haptics. Under Ringers And Alerts, drag the slider left or right. As you drag, an alert will play, so you can hear how the volume changes. Using the Volume buttons on the side of your iPhone won't change the alarm's volume unless you turn on Change with Buttons. 

     

Ask Siri to set an alarm

Here are a few examples of what you can ask:

  • "Wake me up tomorrow at 6:30 AM."

Get help with alarms

Do Not Disturb and the Ring/Silent switch don't affect the alarm sound. If you set your Ring/Silent switch to Silent or turn on Do Not Disturb, the alarm still sounds.

If you have an alarm that doesn’t sound or is too quiet, or if your iPhone only vibrates, check the following:

  • Set the volume on your iPhone. If your alarm volume is too low or too loud, press the volume button up or down to adjust it. You can also go to Settings > Sounds & Haptics and drag the slider under Ringers And Alerts.
  • If your alarm only vibrates, make sure that your alarm sound isn't set to None. Open the Clock app, tap the Alarm tab, then tap Edit. Tap the alarm, then tap Sound and choose a Sound.
  • If you use iOS 11 or later and you connect headphones or speakers to your iPhone, the alarm plays at a set volume through the built-in speakers on your iPhone as well as wired headphones and speakers. It doesn't play through wireless headphones and speakers.

Manually adjusting your iPhone’s time in Settings to change app behavior, like game timers, isn’t recommended and can affect alarms.
