Pure-synthesis ambient noise. Calm, on-device, infinite.
QuietSea is a tiny app that makes ambient noise — white, pink, brown, ocean, rain, binaural. Every sound is generated on your iPhone in real time by a few hundred lines of carefully tuned DSP. There are no audio files in the app, nothing is streamed, and nothing leaves your device.
White and pink for masking conversations. Brown for deep low-end calm. Ocean for gentle swells. Rain for procedural droplets. Binaural for subtle, in-ear contrast (use headphones).
Zero data leaves your device. No account, no cloud, no analytics, no third-party SDKs. QuietSea does not use the microphone — it never listens to you.
