White Noise
Read full descriptionHide full description
The app interface is currently in Korean. Mix rain and noise for bedtime or focus, choose a curve that lowers the sound as you fall asleep, and save the mix to play again another night. Mix rain, waves, forest, fire, wind, fan, and white, pink, and brown noise to choose tonight's sounds. The fade curve shows how the sound level changes and when playback ends. Choose a gradual fade, a steady level, or continuous playback. After 10 seconds without interaction during playback, the screen dims. Tap the screen to return home while keeping the sound playing. Save sound combinations and curves in My Nights, and view your past night records. Bedtime reminders are used only when you enable them. The nine playable sounds are synthesized using the app's scripts. Cafe playback is excluded from this version, and existing saved data is preserved. Core features work offline. The app has no advertising or tracking. In a baby's room, keep the device far from the baby, use a low volume, and set playback to end after the baby falls asleep.

Verdict
The clearest difference is device support: White Noise at 3 against 우연MCS's —. 우연MCS's advantage is iOS requirement (11.0 vs 13.0). On price and in-app purchases there is nothing between them.
