With just one audio session per day, users can experience the benefits in just one to three weeks. The app features calming music and natural background sounds to help users relax, as well as a Sleep Booster to induce the frequency of brain waves for a deep and restful sleep.

The app has separate volume controls for voice, background sounds, and Sleep Booster, and users can disable the Wake Up feature for a more relaxing sleep. The audio sessions can be repeated or set to repeat while the user is asleep, and the background sounds can continue to play after the session ends.
