Set and test a phone alarm

An alarm is scheduled for a time; a timer counts down. Test a short alarm first because sound controls and behaviour vary by device.

Before you start

  • A powered-on charged phone
  • The built-in Clock app
  • Time for a short test

Step 1 of 5: Open Alarm in Clock

Find Clock and its Alarm area. Existing alarms may be listed with switches beside them. Choose the add or plus control to create a new alarm, rather than editing an important existing one by mistake.

Step 2 of 5: Set the right time

Choose a time a few minutes ahead for practice. Check AM or PM if the phone uses a twelve-hour clock. Confirm the displayed hour and minute before proceeding; a wrong half of the day can be easy to miss.

Step 3 of 5: Choose repeat and label

Select repeat days only if you want a recurring alarm. Give the practice alarm a clear label such as Test. Review the selected days rather than assuming that an alarm automatically repeats every morning.

Step 4 of 5: Choose sound and save

Pick an audible sound and check the relevant alarm volume. Avoid None or Silent for a sound test. Save or confirm the alarm if the app requires it, and verify its switch is on in the alarm list.

Step 5 of 5: Test, then remove the practice alarm

Wait for it to ring, then use Stop or Dismiss. Snooze delays an alarm instead of finishing it. Turn off or delete the test afterwards. Keep the phone powered on unless its manufacturer explicitly supports alarms while switched off.

Try it for yourself

Your small practice task.

Create a test alarm a few minutes ahead, hear it, stop it and remove it.

A common question.

Does silent mode affect my alarm?

iPhone Clock alarms ignore Silent and Do Not Disturb with an audible sound selected. Android settings vary; test the sound and volume.
