shush

Shush is not just another sleep app. Every room already has sound — HVAC, traffic, fans, appliances. Most noise apps ignore this and blast full broadband on top of it. Shush listens first, identifies the frequencies already present, and only generates what's missing. The result: full spectrum sound at significantly lower volume, because your room is doing some of the work. No other consumer app does this.

Real time synthesis, no recordings, no samples. Your brain can't latch onto a pattern because there isn't one. Custom smart timer helps you sleep then gets out the way. Tinnitus notch filters. Breathing guide. No content bloat. Adapts to your device. Real Science that works.
