iOS 18 is full of unexpected and surprising features, and we’re still discovering new additions to the iPhone experience. One of the recent discoveries is ‘Sound Actions’, a very useful feature that lets you perform actions by making little sounds and noises.

There are 14 different sounds to choose from. Tap one to set it. Then select the action you want to trigger when you make that sound.

If you're not sure how to make the sound, tap 'Practice' and start making the sounds.

By linking actions to different sounds, you can effectively trigger multiple actions quickly by making just a few sounds.
