## What is Kalma?

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.

Calm features for daily use
• Per-track volume mixing
• Unlimited saved personal mixes
• Offline downloads and cached playback
• Storage management and delete controls
• Internal or SD card storage options
• Wi-Fi only, mobile data, or both for downloads
• Full-screen player with a real-time circular visualizer
• Cross-device sync for saved mixes when signed in
• Sign in with email code, Apple, or Google
• Fully usable without an account

Privacy-friendly by design
Kalma never records audio and never uses your microphone. Your soundscape is created from the app’s library, not from listening to your surroundings.

Free to start. Unlock Kalma Pro with a one-time lifetime purchase. No subscription.

Choose your sounds. Shape the room. Drift off, settle in, or focus anywhere.
