Noctune

Noctune is a beautifully simple ambient sound app designed for relaxation, focus, and sleep - with a gentle sound-based alarm clock and 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.

Wake up without the jolt of a harsh buzzer. Set an alarm with your own choice of sounds - or one of the built-in presets or your own saved mixes - and let it build up gradually over the minutes leading up to your wake time, instead of starting at full volume all at once.

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.
