Subscriptions

Manage or cancel Serein Plus in your Google Play or Apple subscription settings. Use Settings → Restore purchases after reinstalling or switching devices on the same store account.

Sleep timer

Open a scene and tap a preset under the dial, or tap the dial for a custom length (1–720 minutes). Sound fades over the final 30 seconds; pausing playback also pauses the timer.

Custom mixer

In the Mix tab, tap up to six sounds to layer them on top of the scene you are playing. Tap the mixer button to balance each layer, remove one, or save the mix under a name.

Plus sounds

Sounds marked PLUS need a Serein Plus subscription, or watch a short rewarded ad to use one for 24 hours.

Privacy and data

Serein keeps no account and stores preferences only on your device; deleting the app deletes them. See the privacy policy.
