Generative audio engine · built for ADHD focus & burnout recovery

A focus engine that lives entirely on your phone.

AuraFocus4 synthesizes binaural beats, adaptive noise, and a breathing guide in real time. No account to create, no internet connection to use, no data that ever leaves your device — the privacy is architectural, not a setting.

Deep Work · 40Hz Gamma Flow · Alpha/Beta Calm · Theta

01 — Why it exists

ADHD brains stop hearing what doesn't change.

Most focus apps loop the same few minutes of audio. For a novelty-seeking brain, that loop becomes furniture within minutes — the effect fades exactly when you need it most. AuraFocus4 never loops. Every waveform is calculated live, sample by sample, so there's no seam for your attention to learn and tune out.

It's built for two overlapping audiences: people managing ADHD who need external structure for attention and time, and professionals in burnout who need their nervous system talked down from constant activation — often the same person, at different hours of the day.

02 — Inside the engine

Five mechanisms, one continuous signal.

Real-time PCM float synthesis at 48kHz stereo — nothing pre-recorded, nothing streamed.

Brainwave entrainment

Generative binaural beats

Slightly different tones in each ear at a calculated offset — 40Hz for deep work, Alpha/Beta for flow, Theta for calm recovery.

Focus shield

Parametric atmosphere

A variable-slope noise engine tuned by ear, from a deep brown rumble to a brighter texture, to mask whatever's around you.

Bilateral regulation

Neural Flow

Sound drifts slowly left to right, adapted from EMDR bilateral stimulation, to ease task paralysis and shift out of fight-or-flight.

Anti-habituation

The Wobble LFO

A slow internal oscillator subtly shifts volume and texture roughly every 30 seconds — just enough to stay unpredictable.

Somatic regulation

Breathing guide

Box breathing and 4-7-8 patterns with a pulsing visual — the same rhythm animating the orb above this text.

03 — Privacy, verified

Offline isn't a claim here. It's a build decision.

✓
No account or sign-inThere's nothing to create, verify, or lose access to.
✓
No internet connection requiredThe audio engine runs entirely on-device, screen on or off.
✓
No analytics, ads, or trackersNothing about your sessions is ever collected — there's no pipe for it to travel through.
✓
No mental-health data leaves your phoneFor an app used during burnout and ADHD sessions, that boundary matters more than most.
