Nocturne: Sleep Sounds & Noise

Every sound in Nocturne is generated live on your iPhone. It never loops, never
repeats, and never runs out — because there's no audio file to run out of.

Most binaural apps ship stereo files with the same tone in both ears. There's no
second frequency, so there's nothing for your brain to build a beat from. Pull
Nocturne apart and you'll find two real tones, every time.

73+ SOUNDS
- Binaural and isochronic beats — 0.5 Hz to 40 Hz, delta through gamma
- Seven colours of noise — white, pink, brown, grey, green, blue, violet
- Nature — rain, ocean, forest, thunderstorm, stream, fire, night, snowfall
- Generative music — slow chords and singing bowls, composed as you listen
- Full recorded tracks — deep ocean, rain on a roof, felt piano, forest at dawn

BUILD YOUR OWN
Pick any frequency. Layer any bed under it. Set the balance. Save it forever.
No other app in this category lets you own the sound this way.

GUIDED JOURNEYS
Frequencies that move instead of sitting still. Sleep Descent walks you from
10 Hz down to 2 Hz across 45 minutes. Deep Work Ignition ramps you into beta and
finishes on 40 Hz gamma. The 7-Day Neural Reset takes one night at a time.

FOR QUIET EARS
Notched noise centred near 6 kHz — a studied approach for tinnitus relief — plus
violet noise for high-pitched ringing and brown noise for sleeping through it.

BACKDROP MODE
Layer Nocturne under Spotify, podcasts and audiobooks, each at its own volume.
Most apps take the audio session and refuse to share it.

WORKS OFFLINE, FOREVER
No streaming, no buffering, no account. A nine-hour session takes the same space
as a nine-minute one, because both are calculated as they play.

HONEST ABOUT THE SCIENCE
Research on brainwave entrainment is good but not magic. A 2019 meta-analysis
across 22 studies found real effects on anxiety, memory and pain perception, and
the effect grew the longer people listened. We'll never claim DNA repair, IQ
gains or a cure for anything. Read our full evidence summary inside the app.

Nocturne is a wellness app. It is not a medical device and does not diagnose or
treat any condition.
