Four noise frequencies, each tuned for a different state. Scroll through them. The colors tell you where you're going.
01 · Sub Noise · Ultra-Deep Focus
Below the threshold of hearing. A sub-bass field that operates at the edge of perception — felt before it's noticed. For when you need to go somewhere no distraction can follow.
Best for: deep focus, long work sessions, tuning everything else out
White and pink noise show a small but statistically significant benefit for task performance in people with ADHD — while the same noise impairs performance in those without it. This differential effect is neurobiologically distinct, not just a preference. — Nigg et al., JAACAP 2024
Deep Ground · Sub Noise
02 · Brown Noise · Deep Work
A warm, low-frequency rumble — like standing at the edge of a powerful river. Grounds your attention, quiets mental chatter, and keeps you locked in without fatigue.
Best for: deep work, sustained reading, long focus sessions, blocking ambient noise
Brown noise generates more neutral-to-positive emotional responses than white noise, with reduced aversion in extended listening sessions — making it better suited for long work blocks. — Tamariska et al., SAGE Open 2025
Ground · Brown Noise
03 · Pink Noise · Creative Work
Balanced and warm — like steady rain on a quiet afternoon. Softer than white, warmer than brown. Keeps your mind moving without pushing it. The sound of creative momentum.
Best for: writing, designing, brainstorming, creative and analytical work
Pink noise reduces neural noise variability and improves response consistency in sustained attention tasks — particularly in adults with elevated attention challenges. — Rijmen et al., Journal of Attention Disorders 2026
Flow · Pink Noise
04 · White Noise · Sleep & Reset
Full-spectrum static. Equal energy across every frequency — the purest noise blocker. Cuts through chaos and gives your brain a clean slate. Sharp, consistent, total.
Best for: sleep, travel, high-noise environments, full mental reset
A meta-analysis of 12 randomized controlled trials (1,301 participants) found white noise significantly improved sleep quality in adults — lowering sleep quality index scores and improving sleep efficiency. — Systematic Review, Sleep Health 2025
