Frequently Asked Questions
Is RKY Sleep Sounds free?
The app is free to download with a selection of ambient sounds. Premium sounds, advanced sleep timers, and the fade-out feature are available via a one-time lifetime purchase or subscription.
Can I play sounds while my phone is locked?
Yes. RKY Sleep Sounds supports background audio playback. Sounds continue playing when the app is minimized or your device screen is locked.
What sounds are available?
The app includes Rain, Relaxing Sleep, Ocean Waves, Campfire, Forest Wind, White Noise, and more. You can blend multiple sounds together with the custom mixer to create your perfect ambient environment.
What is the Sleep Dim Mode?
Sleep Dim Mode overlays a pure-black filter on your screen to protect your eyes and extend battery life during sleep. You can enable it from the app settings.
Does the app track my sleep data?
No. All sleep timer settings, sound preferences, and bedtime schedules are stored locally on your device. No sleep data is collected, transmitted, or shared with anyone.
How does the fade-out timer work?
The linear fade-out gradually reduces audio volume during the final minutes of your set sleep timer, so you are not woken by an abrupt stop. You can set the fade-out duration in the app settings.
Does it work with Bluetooth headphones?
Yes. RKY Sleep Sounds works with Bluetooth headphones, speakers, and sleep bands. You can connect your audio device before starting playback.
