Conch
Classic shell-to-ear ocean roar, warm and deep.
Brown noiseHold a seashell to your ear. From anywhere.
Cove is an ambient-noise app built around a simple idea: every seashell hums a slightly different sea. Pick a shell, hit play, and Cove synthesises the matching color of noise — brown, pink, gray, white, or blue — for as long as you want it. No streams, no buffering, no internet required after first launch.
Each shell is paired with the noise color whose spectrum best matches its acoustic personality. Audio is synthesised on device the first time you use a shell, then cached for offline play.
