Description
Slumbertone is a clean, ad-free noise machine for sleep, focus, and calm. Choose from white, pink, green, or brown noise—beautifully looped with smooth crossfades and a modern, glass-like iOS design. Set a countdown or a specific stop time, and Slumbertone will fade out gently when it’s time to rest.
