Rain & Ocean Sleep Sounds (name in Vietnamese on Google Play: White Noise: Sleepy Rain) is an Android app that mixes background sounds for sleeping, relaxing, and focusing.

Problem Addressed

Many people find it hard to fall asleep when the room is too quiet or when there are car sounds, noisy neighbors. A consistent background sound like rain, ocean waves, or white noise helps mask those sudden noises. Instead of playing a 10-hour video on YouTube with the screen on all night, you can choose the sounds you like, adjust the volume for each, set a timer, and turn off the screen.

Main Features

• 63 sounds in 9 groups: rain and thunder, sea and water, white/pink/brown/green noise, fans and air conditioners, forest and wind, coffee shop, fireplace, meditation bells
• Mix up to 4 sounds at once (Premium: 8 sounds), each sound has its own volume slider
• 21 preset scenes for quick start
• Timer from 15 minutes to 2 hours, sound gradually fades out and stops, no abrupt interruption
• Continues playing when the screen is off, pause directly from notifications
• Breathing exercises (including the 4-7-8 breathing), sleep diary with weekly charts, screen dimming mode

Who Should Use It

People who have trouble sleeping due to surrounding noise, those who are used to sleeping with the sound of rain or a fan, and those who need consistent background noise when studying or working.

How to Get Started

Download from Google Play (Android), open the app, tap on a few sounds or select a scene, adjust the volume, and set a timer. No account creation is needed; favorite mixes and sleep logs are saved directly on the device. The app supports 4 languages: Vietnamese, English, Spanish, and Portuguese.

What's Different

Mix multiple layers of sound and adjust each layer instead of just playing a pre-recorded track; the timer gradually fades out; the Premium package is a one-time purchase, not a monthly subscription.

Ads and Premium

The app displays ads. Premium (one-time purchase via Google Play) removes ads, unlocks all sounds, scenes, and breathing styles, and mixes up to 8 sounds. The app is for relaxation purposes, not a medical device.
