Settle into a calmer space with sound. Kalma is a premium ambient-sound app for sleep, focus, meditation, travel, and everyday relaxation. Build the atmosphere you need with high-quality stereo sounds, gentle controls, and a quiet interface designed to stay out of the way. Create your own soundscape Layer rain on a tin roof with distant thunder. Add a soft fan, brown noise, ocean waves, a forest stream, a crackling fireplace, or a quiet café. Kalma lets you mix multiple sounds together and adjust the volume of each layer separately, so your soundscape feels personal, balanced, and natural. Made for bedtime and travel Play audio in the background while your screen is locked. Set a sleep timer for 5, 15, 30, or 45 minutes, 1h, 2h, or a custom time, and let Kalma stop playback gently when you are ready. Download sounds to your device so they are available offline on flights, trains, hotels, nighttime routines, and low-connectivity moments. A large library, carefully organized Explore +200 high-quality stereo sounds across 38 categories. Start from curated mixes for sleep, focus, meditation, nature, relax, cozy spaces, travel, urban ambience, and animals, or save your own blends in My Mixes with a name and cover.
