How to Set Alarms on an iPhone
Some of the best things about the Alarm function are that you can have multiple alarms, choose the days an alarm should repeat, select the sound you want it to have, and add a snooze function. If you want the alarm to vibrate only, leave your iPhone in Ring mode but turn the volume completely down.
Keep in mind that the alarm sounds even when your iPhone is in Silent mode.
Here's how to set alarms:
Tap Clock on the Home screen.
Tap the Alarm button at the bottom of the screen.
Tap the plus sign in the upper right corner.
The Add Alarm screen opens.
Use the rotor to set the time you want the alarm to sound.
(Optional) Tap Repeat if you want to create a repeating alarm.
You can choose any day of the week or a combination of days, which means you can have a Monday through Friday alarm, which is labeled Weekdays on the alarm list, whereas a Saturday/Sunday alarm is labeled Weekends.
Tap Back after you choose the days you want the alarm to repeat.
(Optional) Tap Label to name your alarm.
The Label screen opens with a field and keyboard. Click the X on the right end of the field to delete the default Alarm label, type the name you want, and then tap Back.
Tap Sound to choose the sound you want for your alarm.
Choose a sound from the list — scroll down to see all the options, which include ringtones you purchased or created. You can buy more tones by tapping the button at the top of the list, which takes you to the iTunes store.
A neat new feature of iOS 6 or later is using a song for an alarm sound. Tap Pick a Song and then tap the song you want from the music collection on your iPhone. You can add more than one song and assign a different song to different alarms.
Tap Snooze On or Off.
Snooze lets you tap the alarm off when it sounds. After ten minutes, it sounds again.
The alarm is added to the list of alarms on the Alarm screen. Use the switch on the right to turn the alarm on or off so you don't have to add and delete alarms you use frequently.
When the alarm goes off, just tap the screen to turn it off.
To make changes to an existing alarm, tap the Edit button on the top left of the screen, and then tap the name of the alarm you want to change. The Edit Alarm screen opens, which is the same as the Add Alarm screen but has the information of the selected alarm.
To delete an existing alarm, tap the Edit button. Tap the red button to the left of the alarm time, and then tap the Delete button that appears on the right. Tap Done after you finish.
When you set an alarm, the alarm icon, which looks like a clock, appears in the status bar at the top of your iPhone's screen.
