Glowm is your personal soundscape mixer. Blend white noise, nature sounds, city noises, chill beats, and real artist soundscapes into a mix that's entirely yours, then watch the whole app bloom with the colors of your sound. A LIVING GLASS ORB Your mix, visualized. Every sound has a signature color, and the orb (and the entire app) shifts to match your blend. Silence rests in deep purple; sound blooms everything into color. MIX AND BLEND FREELY • 60+ sounds across six collections • Color noise: white, pink, brown, blue, violet, and green • Nature & life: rain, thunder, creeks, crickets, and an owl waking up • City life: coffee shops, wet streets, and NYC nights • Chill beats: lo-fi loops cut to the same bar, so stacked beats stay locked together • Binaural beats: Delta, Theta, and Alpha tones (best with headphones) • Soundscapes: ethereal beds of choir, lunar pads, and starlight ARTIST SOUNDSCAPES Real artists, released as stems you can remix. Fade the layers of one composition in and out; everything stays locked to the pulse. MADE FOR SLEEP AND FOCUS • Runs all night, with Lock Screen and AirPods controls • One-tap quick mixes: Sleep, Focus, Chill, Meditate, and more • Save favorites and bring them back in a tap • A built-in night light: pull down and the orb fills the screen QUIET BY DESIGN No ads. No account. No tracking. A generous free library, sound packs at $1.99 each, and Glowm Unlimited ($3.99/month or $19.99/year) for everything, including every sound we ever add.
