#TIL iPhones have a built-in background noise generator. It has limited options but sounds way better than many apps I’ve tried. 💯

Go to Accessibility -> Audio/Visual -> Background Sounds -> Sound -> Dark Noise (or other preferred sounds like Stream or Ocean)

After that, go to Accessibility -> Accessibility Shortcut -> Background Sound, and you’ll be able to activate the noise with a triple side button click
