Focus & Sleep Sound Mixer
Mix your own ambient soundscape — rain, ocean, fire, wind and noise, all synthesized live — with a sleep timer that fades out. Great for focus and sleep.
🔒 100% on-device. Every layer — rain droplets, ocean swells, fire crackle, thunder, birdsong — is generated live with the Web Audio API. No audio files, no streaming, no network. It runs forever and never repeats, which is exactly what an AI chat can't hand you.
