iPhone alarm too quiet? How to make it louder

Turn up the right volume

The iPhone has two volumes that matter here, and it is easy to change the wrong one. The volume buttons control media while audio is playing and the ringer and alerts the rest of the time. Turn the buttons up while a video plays and your alarm stays exactly as quiet as it was.

• iOS 26 and earlier: Settings > Sounds & Haptics, then drag the slider under Ringtone and Alerts. Apple's guide for these versions says this slider sets the volume for all sounds, and the Clock alarm follows it.
• iOS 27: alarms and timers match the ringtone volume by default. Under Sounds & Haptics you can turn off Match Ringtone Volume under Alarms and Timers and give alarms their own slider, which lets you keep calls quiet and the alarm loud.
• A sleep schedule alarm: the wake-up alarm from a Health sleep schedule has its own Alarm volume slider. In Clock, tap Alarms, then Change, and scroll to Alarm Options.

As you drag the slider, an alert plays so you can hear the level. Set it with nothing else playing. If the alarm doesn't sound at all, start with the checklist for an alarm that didn't go off.

Stop the volume buttons turning it down

If Change with Buttons is on, pressing a volume button while nothing is playing changes the ringer and alert volume. A phone in a pocket or bag gets pressed, and tomorrow's alarm is quieter. Turning Change with Buttons off locks that volume, so the buttons only control media, and you set the alarm level with the slider in Settings instead.

Attention Aware Features can lower it when you look

On iPhones with Face ID, Apple says Attention Aware Features use the TrueDepth camera for things like dimming the display or lowering the volume of alerts while you are looking at the iPhone. If your alarm drops in volume the moment you pick the phone up, test with this off: Settings > Face ID & Passcode > Attention Aware Features.

Apple's page describes alerts rather than alarms specifically, so treat this as a suspect to rule out, not a guaranteed cause.

Check the speaker limits

Two settings cap everything the built-in speaker plays:

• Volume Limit: in Settings > Sounds & Haptics, if Limit Maximum Volume is on, raise its slider or turn it off. On iOS 27 it sits under Built-In Speaker.
• Reduce Loud Sounds (iOS 27): also under Built-In Speaker, it softens loud sounds from the speaker. An alarm is meant to be loud.

If Screen Time was set up for your iPhone, the speaker volume limit may be locked there.

Uncover the speaker

A loud alarm into a pillow is a quiet alarm. Leave the phone face up on a hard surface, not on the mattress or under a pillow. Apple's speaker troubleshooting also suggests removing cases, films and screen protectors, checking the speaker opening for dirt, and cleaning it with a small, soft, dry brush. Then drag the Ringtone and Alerts slider: if you hear nothing, or the speaker button on the slider is dimmed, the speaker may need service.

Headphones shouldn't be the culprit for the Clock app: Apple says its alarm plays through the built-in speaker as well as wired and wireless headphones. Other apps can handle audio differently, so test them with your headphones connected.

Choose a sound that carries

Some alarm sounds are soft by design, and songs with a quiet intro can spend their first seconds barely audible. If the alarm is on but doesn't reach you, try a sharper sound before turning anything else up. In Clock: Edit, tap the alarm, then Sound.

Third-party alarm apps can't make it louder

No App Store app can turn up your iPhone's volume for you. Apple's developer documentation is direct: only the user can set the system volume. An app that promises the loudest alarm on iPhone is still playing at the level you chose.

That includes WakeOps. What it controls is what plays: a System choice (on iOS 26 and later, the iPhone's own alarm sound) plus 70 original tones in seven moods, including one called Annoying on purpose, and you can add your own sound from a video or a file, trimmed to a 10, 15, 20 or 25 second loop. On iOS 26 and later WakeOps alarms ring through Silent mode and Focus. On iOS 17.6 to 18 they are Time Sensitive notifications, which follow the Ringtone and Alerts volume and make no sound in Silent mode.

If the alarm reaches you and you still don't get up, volume isn't the lever. Why people sleep through alarms and alarms for heavy sleepers cover what is.
