## What is Tonic?

Fall asleep faster with white noise, pink noise, and brown noise. Tonic generates unique, never-repeating sleep sounds and focus music—completely offline, no ads, no tracking.

Unlike apps that loop pre-recorded tracks, Tonic creates fresh soundscapes using real-time audio algorithms. Every session is one of a kind.

SOUND TONICS — Algorithmically Generated

› Bright — Crisp white noise that masks distractions and sharpens concentration
› Rest — Warm pink noise scientifically linked to deeper, more restorative sleep
› Focus — Deep brown noise that quiets mental chatter and promotes flow states

NATURE SOUNDS — Botanical Essences

› Rain — Gentle rainfall on a windowpane
› Ocean — Rhythmic coastal waves
› Forest — Birds and rustling leaves in woodland serenity

PERSONALIZED FOR YOU

Take a brief quiz and receive a tailored sound prescription—your ideal noise type, volume, and duration for your specific needs.

DESIGNED FOR SLEEP

› Set precise timers: 15 min, 30 min, 1 hr, 2 hr, or 8 hr overnight
› Adjust intensity from gentle whisper to full immersion
› Automatic fade-out gently eases you awake
› Background playback continues with screen locked
› Lock screen controls for seamless operation
› Built-in hearing safety indicators protect your ears
› Works completely offline—no internet required
› No accounts, no ads, no tracking

A DIFFERENT KIND OF SOUND APP

Tonic draws inspiration from Victorian apothecaries—places where remedies were carefully formulated and dispensed with intention. Every detail, from the elegant dark interface to the amber-gold accents, is designed to feel like a sanctuary.

Whether you're battling insomnia, seeking deeper focus for work, or simply craving a moment of calm, Tonic dispenses the perfect sonic remedy.

Cork your distractions. Dispense tranquility.
