Say goodbye to heavy, battery-draining MP3 loops. Pure procedural soundscapes, crafted by mathematics.
Shape your perfect soundscape.
Don't just listen to pre-recorded tracks. Mold the audio in real-time with our hybrid engine.
Two engines fused into a single on-device experience:
The first real-time indicator that reveals the efficiency of your mix. Shape the sound while keeping battery consumption perfectly under control.
Engineered with Apple excellence.
Typical sleep apps read massive MP3 audio files on loop, keeping the CPU awake. NoxNoise generates waveforms mathematically on-the-fly, allowing the processor to remain in a ultra-low-power deep sleep.
Describe your desired ambient setting, and the on-device language models will instantly configure the synthesizer variables for you.
Apple Intelligence and audio synthesis happen 100% OFFLINE. No vocal data, sound, or habit ever leaves your device.
Subtle, rhythmic taptic engine pulses synchronize with ocean wave structures to somatically lower your heart rate and ease transition to sleep.
Your configurations sync seamlessly over iCloud. Share entire custom presets using <1KB light URLs that unpack instantaneously on another device.
Experience sound natively in 3D. A breathtaking floating glass interface positioned in your physical room, generating real-time acoustics that interact with the physical surfaces around you.
Frequently Asked Questions
Other apps stream pre-recorded audio files on repeat. This requires constant memory accesses and audio buffer reading, draining your phone's battery. NoxNoise uses procedural synthesis, generating audio mathematically on the CPU. It fits in 2.0s buffers and matches the native sample rate, allowing components to enter sleep states.
No, the core procedural synthesizer and sliders are fully customizable manually. Apple Intelligence is an optional assistant to make set up easier using conversational commands (requires iOS 18.2+ on compatible hardware).
No. NoxNoise is 100% ad-free, respects your privacy, collects zero analytics data, and does not require an active internet connection to play sound.
