Noctune

Mathematical Zen

About this app

Noctune is a beautifully simple ambient sound app designed for relaxation, focus, and sleep - with seamless casting to your favorite speakers.

Create the perfect atmosphere using calming soundscapes like rain, wind, ocean waves, white noise, and gentle textures. Whether you’re winding down for the night, concentrating during work, or filling your home with peaceful background sound, Noctune makes it effortless.

Unlike most ambient apps, Noctune is built with casting at its core. Send sound directly to Chromecast-enabled speakers, smart displays, or audio systems and let the calm flow through every room.
