Smartphone apps may be convenient, but phone speakers are incapable of producing full-spectrum, natural sound like SNOOZ. Think about playing music – phone speakers are great in a pinch but, if you’re going to spend time listening to music, you’re going to want to find headphones or better speakers.
Further, many digital apps or machines rely on looping tracks so your mind picks up on the pattern and the device that is supposed to help you sleep actually has the opposite effect. SNOOZ doesn’t rely on a recording, its sound is truly random and natural, and it never loops.
