To set an iPhone timer, open Clock > Timers, choose the duration, select an audible sound under When Timer Ends, and tap Start. If a timer finishes silently, first check that it is not set to Stop Playing, then check the timer volume and run a short test.
Stop Playing is a sleep-timer action that ends audio or video playback. Choose a sound when you want the timer to alert you instead.
Before you start
These instructions are for Apple's built-in Clock app. A workout app or another timer app can depend on its own sound and notification permissions, so use that app's instructions if you are not using Clock.
Check Settings > General > About for the iOS version if your controls differ. Recent versions support multiple timers; older versions can show a singular Timer tab. In current iOS, timer and alarm volume can also have a separate control.
For anything where missing an alert would matter, verify the sound under the conditions you plan to use. Run the short check below on the device and audio setup you intend to use for the longer timer.
Set an audible countdown
- Open Clock and tap Timers.
- Set the desired hours, minutes, and seconds. Check the units so a five-minute task does not become five hours.
- Enter a Label if you want a recognizable name, such as Tea or Laundry.
- Tap When Timer Ends, or the equivalent Sound control shown on your version.
- Choose an audible tone. Make sure Stop Playing is not selected when your goal is an alert.
- Tap Set if the sound picker offers it, then return to the timer.
- Tap Start, or the start triangle on a layout that uses an icon.
- Check that the remaining time is counting down. A duration entered in the setup screen is not proof that the timer has started.
Apple's timer guide says the timer continues when you open another app or the iPhone goes to sleep. You do not need to leave Clock visible throughout the countdown.
Run a short sound check
- Create a one-minute timer with an ordinary audible tone and a label such as Test.
- Confirm the countdown starts.
- Leave Clock, lock the iPhone, and keep it nearby in the situation where you will use it.
- Wait for the timer to finish and check whether you hear the alert and see the notification.
- Stop the completed timer. If it was silent, change one relevant setting below, then repeat the check.
Testing the locked phone catches a different situation from hearing a tone preview while Settings is open. If you rely on a connected headset or speaker, check that setup too. Keep a second way to track an important deadline until the timer is behaving reliably.
Fix Stop Playing instead of a sound
Open the timer's When Timer Ends or Sound choice and inspect what is selected. If it says Stop Playing, choose a tone, save the selection, and start a new short timer.
A recently reused timer can carry an earlier label or sound choice. Review those details instead of assuming every timer starts with the sound you prefer.
If you deliberately want a sleep timer, choose Stop Playing at the bottom of the sound list, tap Set, and start it. Apple documents this for stopping audio or video after a chosen period. Check that the playback actually stops in the app you use; do not assume every device or playback route is identical.
Our Apple Podcasts sleep-timer guide explains the player-specific timer in that app, and our guide on following podcasts on iPhone covers adding shows to it. After using a sleep timer, recheck the next Clock timer before relying on an audible alert.
Set the correct volume for your iOS version
Media volume and timer volume are not always controlled by the same slider. Raising a song's volume is therefore not a complete timer-volume check.
On iOS 27:
- Open Settings > Sounds & Haptics.
- Find Alarms and Timers.
- Check Match Ringtone Volume. If you want a separate timer level, turn this match option off.
- Adjust the Alarms and Timers slider to an audible, comfortable level.
- Run the short timer test again.
With matching enabled, check the ringtone volume that alarms and timers follow. Apple's sound and vibration guide explains the separate iOS 27 levels for alarms/timers and alerts/system sounds.
On iOS 26 and earlier, check the Ringtone and Alerts or ringtone volume slider in Sounds & Haptics. That earlier layout does not offer the same separate Alarms and Timers slider. Do not search indefinitely for a newer control on an older release.
The volume buttons can operate on different audio depending on what you are doing and your Change with Buttons preference. Open the relevant Settings screen to make the level unambiguous.
Check that the right timer is running
A paused timer has not finished its countdown. Return to Clock > Timers and look for the running timer, its label, and remaining time. Resume it with the play control if it is paused, or create a new timer if you are uncertain which one you selected.
Current iOS supports adding another timer with the plus control after starting one. You can also use preset durations or reuse a recent timer. Give concurrent timers distinct labels so a five-minute tea timer is not confused with a longer cooking timer.
Tap a preset or recent timer to inspect its label and sound when needed. If reusing one produces an unexpected result, set up a fresh custom timer with an audible tone instead of deleting every saved timer.
If you asked Siri to set a timer, check Clock or the timer activity on the Lock Screen. With several Apple devices nearby, verify which device handled the request. Hearing Siri respond elsewhere does not prove that the countdown you intend is running on this iPhone.
Pause, stop, repeat, or remove a timer
Use the pause control beside a running timer to stop the countdown temporarily, then use play to continue. When a timer finishes, use Stop to dismiss it or Repeat to run it again when those choices are shown.
To remove a timer from the list, swipe left on it and use the displayed delete control. The Edit control can provide a way to remove several. Check their labels before removing them; deleting saved timers is unnecessary for a simple sound change.
For a specific time of day, use an alarm instead of a duration-based timer. Our iPhone alarm guide explains changing or turning off an alarm without confusing its controls with Timers.
If the short test still makes no sound
Play a familiar audio clip to check whether the device can produce sound. Then inspect the selected timer tone and the correct volume setting again. A silent custom tone can be selected even though it has a name in the sound list; try a standard audible tone for diagnosis.
Review any connected wired or Bluetooth audio device. Disconnect it for a comparison test if you need to establish how the iPhone speaker behaves. Avoid assuming that the music output route proves where every Clock alert will play.
Restart the iPhone and create a fresh short timer if the sound choice and volume look correct. Check Settings > General > Software Update for an available fix. If the speaker also fails with other audio, investigate that broader sound problem rather than repeatedly changing the timer.
Do not erase the phone or reset all settings as an initial timer fix. Those actions have a much broader effect. If the problem persists after a fresh test, collect the iOS version, selected tone, volume behavior, and whether other sounds work before contacting Apple Support.
Will Silent mode silence every Clock sound?
Do not use Silent mode as a universal sound-off guarantee. Apple explicitly notes that Clock alarms can sound through the speaker while Silent mode is on. Check your timer's selected action and test the specific result you need.
Can I get a vibrate-only timer with Stop Playing?
Stop Playing is a playback-stopping action, not a documented vibrate-only alert choice. Do not rely on it to provide a quiet vibration notification.
Finish by confirming a labeled countdown, an audible tone, and a successful short test. That gives you a clearer basis for using the longer timer.
