Frequently asked
Does it keep playing when my phone locks?
Yes. WhiteNoise Pro plays in the background, so sound continues when the screen is off or you switch apps, and you can control it from the Lock Screen.
Can I mix multiple sounds?
Yes — layer several sounds and set each one’s volume in the Mixer.
How does the sleep timer work?
Pick a duration and the audio gently fades out and stops at the end — even with the screen locked.
What does Pro unlock?
A one-time purchase unlocks unlimited sound layers and the full premium sound library. Core sounds and the timer are free.
I bought Pro on another device — how do I restore it?
Open Settings and tap “Restore Purchases.” Pro is tied to your Apple ID.
