iOS builtin sleep sounds
You know all those apps that play "sleep sounds" β white noise, rain, ocean, etc.? I know them well. My wife is adept at finding the scuzziest of those apps and accidentally buying their outlandish subscriptions. π
Which makes me pleased to learn that iOS can do this out of the box! The feature is called background sounds. To try it out, go to Settings > Accessibility > Audio & Visual > Background Sounds. Here's the official support doc.
Cheers!
