Ocean Waves - Relaxing Sound is a free iPhone app developed by Codepaint Inc. that allows users to listen to the calming sound of waves. With over 300,000 downloads, it is a popular player for those who want to relax or focus on something. The app has a sleep timer function, which is available on the Apple Watch as well.

The app is simple to use, with a play-pause button on the screen to control the wave sound. The sleep timer can be set by pressing the timer button and controlling the dial. Once the time passes, the wave sound stops. The app also continues to play the wave sound automatically when it goes into the background, allowing users to use other apps while listening to the sound.

While the free version of the app has ads, a paid version is available for $7.99, which removes the ads and allows users to set a timer for up to 12 hours. The paid version also offers a night mode with reduced brightness, suitable for nighttime use. It is important to note that cancellations and refunds are not accepted for the paid version, and users will be charged via their iTunes account.

With its simple design and calming sound, Ocean Waves - Relaxing Sound is an excellent choice for those seeking a peaceful respite from the stresses of daily life.
