Editing the iPhone Wake Up alarm in Health and in Clock, field by field

Health, Browse, Sleep, Sleep, then Edit under Schedule, then the Alarm switch. That path is where the iPhone’s Wake Up alarm is born, and there is a second door into the same alarm through the Alarms tab in Clock. The two are not different alarm types. The Wake Up alarm is one alarm with two editors, and the editors expose different fields.

Field names follow Apple’s iPhone User Guide as of iOS 26; nothing here was tested on a device. The pages used are the guide’s entries on sleep schedules and on changing the wake up alarm in Clock.

Fields in each editor

Field	Health, sleep schedule	Clock, plain alarm
Time	Drag the Ringing Alarm handle on the dial	Time picker
Days	Per schedule; extra schedules allowed	Per alarm (Repeat)
Sound	Chosen from the list	List, or Pick a song
Song from your library	Not selectable	Selectable
Volume	Own control in the alarm options (see the iOS 27 note below)	Follows the Ringtone and Alerts slider
Vibration	Yes	Yes
Snooze on or off	Yes	Yes
Snooze length	Yes, in the iOS 26 guide	Yes, per alarm
Skip one occurrence	Apple Watch (not verified here)	Not found in the iPhone guide

The song row is the one Apple states outright: you cannot select a song for a sleep schedule alarm, though you can for a Clock alarm. Everything else in the table is a presence or absence of a control, which is the useful way to read it. If a feature has to be in the alarm that gets you out of bed, the Clock editor has the superset.

On volume, iOS 27 changes the Clock side. Under Settings, Sounds & Haptics, a Match Ringtone Volume switch in the Alarms and Timers section can be turned off, and a separate alarm slider appears. The quiet-alarm checklist walks through that menu. On iOS 26 and earlier, a Clock alarm is tied to the Ringtone and Alerts slider.

Change Next Alarm Only versus Change This Schedule

The Wake Up alarm also appears in the Alarms tab of Clock, and Apple documents editing it there: Alarms, Change, Alarm Options. The fork comes at the end. After tapping Done you choose between “Change Next Alarm Only” and “Change This Schedule”. The second one, in Apple’s words, also updates the recurring wake up alarm in your sleep schedule.

Treat that as a two-state write. One option records an exception for the coming alarm and leaves the schedule alone. The other mutates the schedule, so Tuesday’s one-off earlier start becomes every Tuesday’s start. The prompt arrives after you have finished adjusting the time, which is the moment attention is lowest, and the two labels are close to identical in length and shape.

A plain Clock alarm has no such fork. Edit it and the edit is the alarm.

Snooze length is stored per alarm

iOS 26 lets snooze run from 1 to 15 minutes per alarm, against the fixed 9 minutes of earlier versions (MacRumors and 9to5Mac coverage of the release, 2025), and Apple’s guide for sleep schedules lists a snooze duration among the alarm options once the Alarm switch is on. Because the setting is stored per alarm, a changed snooze length on a Clock alarm does not carry over to the Wake Up alarm. The per-alarm snooze setting is worth checking in both places after the update.

Failure modes and open questions

These are not bug reports. Each follows from the documented controls, reasoned from Apple’s text and not reproduced on hardware.

• Scope mix-up. Choosing Change This Schedule for a one-night change moves every future occurrence. The reverse mistake, choosing Change Next Alarm Only for a permanent change, reverts after one morning and looks like the setting did not save.
• Schedule exists, alarm off. A sleep schedule and its Alarm switch are separate. A schedule can drive Sleep Focus and bedtime reminders while ringing nothing.
• Day coverage. With a weekday schedule and a weekend schedule, a day belongs to exactly one of them. A schedule whose days were edited for a trip can leave a day with no alarm at all.
• Two alarms, one hour. If a Clock alarm is also set for 6:30, the Wake Up alarm and the Clock alarm both exist and silencing one leaves the other. A tidy Alarms tab is the cheapest check, and the walkthrough for pruning leftover alarms covers it.
• Song fallback. Clock lets you pick a song, and Apple’s own text says songs must be on the device. A guide dating from iOS 12 reports that an undownloaded song falls back to the Radar tone; that report is old and has not been reconfirmed for iOS 26.

Four questions remain open, and each is cheap to settle with a spare evening and a schedule set five minutes out. Does Sleep Focus end at the wake-up time or only when the alarm is dismissed? One MacRumors forum user reported Focus turning off at the scheduled time after skipping an alarm on Apple Watch, which is a single user report and not Apple’s documentation. Which sound is preselected for the Wake Up alarm? How long does an ignored alarm keep sounding, given that Apple publishes no figure? And does the Change Next Alarm Only exception survive a restart or a time zone change?

FAQ

What happens on weekends if I switch the Alarm off on a weekend schedule?

Each sleep schedule carries its own days, bedtime, wake-up time and alarm options. A weekend schedule with its Alarm switch off leaves Saturday and Sunday silent while a separate weekday schedule keeps ringing. The schedule can still drive Sleep Focus and bedtime reminders.

How do I skip the Wake Up alarm for one night?

Apple’s materials describe a Skip for Tonight control on Apple Watch that applies to the next wake-up alarm only, and for iPhone they describe turning the alarm off in Alarm Options and finishing with Change Next Alarm Only. The iPhone guide shows no dedicated skip button, and neither route has been tested here.

Can I use a song from my music library as the Wake Up alarm?

Apple states that a song cannot be selected for a sleep schedule alarm, though it can for a Clock alarm. For a Clock alarm the song has to be on the device, so a song that is only in the cloud is a poor choice for the alarm that must ring.
