We're please to give you and your loved ones a month of free use of the Sonic Sleep app. We use it to optimize my quality of sleep. Sonic Sleep uses the science of sound to help you sleep. A good night's sleep sets each person up for success the next day. Our app includes a new technique of making your sleep deeper with a special sound that we play at the right stage of your sleep. This helps you feel more rested and rejuvenated the next day.
