I needed this like…last week!
If you’re a fan of having sound on while you sleep, (like me) and are Team iPhone, (also like me) then there’s a feature that may help you, and you didn’t even know it!
All iPhones running on iOS 15 or later have a white noise feature that is built-in into the phone!
The setting is labeled as “background sounds” on your iPhone and can be accessed by going to your Settings, then clicking Accessibility, Audio/Visual, and then choosing Background Sounds.
You can choose from several different sounds, including rain, stream, ocean, balanced noise, bright noise, and dark noise. You can also adjust the sound’s volume.
