One tap to begin

Your first mix is white noise, a 30-minute timer and low app volume. Playback never starts automatically. Tap the home play button or a suggested mix to begin. You can also choose from 22 sounds in the library.

Mix two sounds
Choose ‘Add a second sound’ in the player. Adjust each volume independently and save up to 20 presets.

Timer
Choose 15, 30, 45, 60 or 90 minutes, enter 1–480 minutes, or listen until you stop. Changes take effect only when you tap Apply. Pausing preserves the remaining time. The default ending fade is 10 seconds.

Free playback
All sounds, mixing, timers, favorites and presets are free without internet. Playback continues while the app is visible. Locking the screen or switching apps also pauses playback. Tap to resume after returning.

Background playback
Choose one of three ways to listen with the screen off or while using another app: complete one rewarded ad for 24 hours from its verified completion time, subscribe monthly, or pay once for lifetime access. Rewarded access requires no payment and does not accumulate. All three remove ads while active. Otherwise a banner appears below the menu while paused or stopped; a rewarded ad plays only when you choose it. There are no interstitial ads or play tokens.

Access and restoration
Free offline playback needs no access verification. Ads, server verification, subscription verification and restoring Play purchases after reinstalling require internet. Closing an ad or no-fill never blocks free playback. If ad verification is delayed, return to the app shortly to refresh. Rewarded access does not transfer across devices or reinstallations. Time-limited background access needs one online verification after reboot. Previously issued access remains valid until its original expiry.

If access expires while already playing, the current session is protected until the earlier of its current timer end or 8 hours after expiry. Pausing, changing sounds or changing the timer cannot extend this end time. Running a preset starts a new session.

Calls and headphones
Both sounds pause together after calls, competing media or headphone disconnection. Resume manually when ready. The app never automatically plays after a reboot or force stop.

Volume
The app's volume percentage does not measure acoustic dB at your device. Start low and adjust for your surroundings.
