What Lull Does
Start free, no account
A built-in library of free, public-domain audiobooks — classics from LibriVox — streams the moment you open the app. Nothing to sign up for.
Bring your own Plex library
Have your own audiobooks on a Plex Media Server? Sign in and Lull auto-discovers it, browses by author, searches your shelves, and plays single-file M4Bs with full chapter support.
A sleep timer that's for sleep
Set a timer from 1 to 90 minutes, or stop at the end of the current chapter. Your book fades out smoothly, then sleep sounds take over.
Mix your own sleep sounds
Layer ocean, rain, a crackling fireplace, a fan, crickets, thunderstorm, wind, and brown, pink, or white noise. Optional binaural beats for deep sleep, relaxation, or dreaming (use headphones).
Shake to come back
Still awake when the sounds kick in? Shake your phone — or use your headset or lock screen — and Lull brings the book back and resets the timer for the same length as last time.
Made for the nightstand
Resume right where you dozed off, every time. Download books for offline, gapless listening, with full lock-screen and Control Center controls and background audio.
Private, quiet, and free
Lull collects no data — no ads, no tracking, no analytics. Free audiobooks come from LibriVox, hosted by the Internet Archive; your Plex books talk only to your own server. The app is free, with an entirely optional tip jar if it helps you drift off.
Lull is launching soon. In the meantime, you can review how it handles your data.
