NOTHING EVER LOOPS Every sound in Sleepdrift is generated on your device in real time by a synthesis engine. None of it is a recording being played back. That means there is no loop point, so there is no seam to hear at 3am - and it works with no internet connection at all.

THE FADE-OUT SLEEP TIMER Set it for 10 minutes or 8 hours. Over the final stretch the sound gets quieter and quieter until it reaches silence, so the audio never cuts out and jolts you awake.

PLAYS ALL NIGHT Background audio, locked screen, Control Center, AirPods. It keeps playing while you use other apps.
