About this Sleep Timer
Pick how long you want before winding down. The screen gently dims as time passes, so you’re not staring at a bright display while falling asleep. Browsers don’t allow a webpage to stop audio playing in another app or tab, so this won’t silence music or a podcast elsewhere — it’s a simple, distraction-free bedtime countdown for this screen.
