Using Sleep sounds

Sleep plays a soothing sound to help you drift off. Open the menu, tap Activities, then tap Sleep.

🌙 Start a sleep session

1. Choose a sound under Background Sound.
2. Under Stop after, choose 15, 30, 45, or 60 minutes, or All night.
3. Tap Start, then lock your phone. Your sound keeps playing.

The sound fades in gently and fades out slowly when your time is up. Koi remembers the sound and stop time you used last, so next time you can tap Start straight away.

📱 While it plays

You can pause or stop the sound from your lock screen or notifications. If a phone call comes in, your sound picks up again afterwards. To end the session early, tap Stop or leave the Sleep page.

🎶 Choosing a sound

• Included for everyone: Underwater, Night, Day, and Creek.
• With Koi Gold: Waves, Rain, Birds, and Forest.
• From your pond: the sounds of Koi's pond sceneries. Sounds from scenery you own are ready to play. For a scenery you don't own yet, you can buy it with Koin right from this row, and your pond keeps its current scenery until you choose to change it.

Koi Gold members can play every scenery sound.
