Kalma: Relaxing Sounds

Sleep sounds, white noise, nature sounds and calm soundscapes, mixed your way.

Kalma is a premium ambient sound app for sleep, focus, relaxation, meditation and travel. Choose from +200 high-quality stereo sounds, layer them together and create a peaceful background that fits your moment.

Build your own soundscape
Mix rain on a tin roof with brown noise. Add ocean waves, wind, forest streams, a soft fan, a crackling fireplace or a quiet coffeehouse. Kalma is not just a single-loop sound player. You can layer multiple sounds at the same time and adjust the volume of each track separately, so every mix feels personal and balanced.

Made for sleep, focus and travel
Use Kalma for bedtime routines, reading, studying, deep work, meditation, screen-free evenings, baby sleep routines and everyday noise masking. Background playback keeps your soundscape going when the screen is locked. A sleep timer can stop playback automatically after 5, 15, 30 or 45 minutes, 1 hour, 2 hours or a custom time.

Offline sounds for real life
Download your favorite sleep sounds, white noise, rain sounds, nature sounds and personal mixes to your device. Once cached, they work without a network connection, making Kalma useful for flights, trains, hotels, low-signal nights and quiet moments away from Wi-Fi.
