Choose from 6 calming sounds, set a smart alarm, and track your sleep — all in one app. CALMING SOUNDS Pick from white noise, brown noise, and pink noise for free. Upgrade to unlock green noise, rain, and fan sounds. Mix multiple sounds together to create your perfect sleep environment. SMART ALARM Set your wake-up time and let SleepTone find the best moment to wake you.
