## What is DimDim zZ?

DimDim is a minimalist sleep sound app for nights when falling asleep feels hard. No complicated setup — just one sound ticket that carries you off to sleep tonight.


■ A guided journey into sleep
DimDim is designed around three natural stages of falling asleep.
· Wind-down — The first 15 minutes to settle your mind
· Drift — The next 30 minutes as consciousness fades
· Deep — Sustained sleep through the rest of the night
Each stage shifts to the right frequency automatically, following the natural flow of sleep.

■ A range of frequencies
· Brainwave bands: Delta (deep sleep), Theta (light sleep), Alpha (relaxation)
· Solfeggio tones: 174Hz, 396Hz, 528Hz, 639Hz, 852Hz
· Natural tuning: 432Hz, 7.83Hz (Schumann resonance)
· Noise: White, Pink, Brown

■ Soothing companion sounds
Pair any frequency with a gentle sound that fades out naturally over 30 minutes.
· Nature: Rain, ocean, stream, fireplace, birds
· Cosmic & mechanical: Space, submarine, airplane, fan
· ASMR: Pencil writing, page turning
· Meditation: Heart Sutra, Tibetan bowls, wind chimes

■ Your own presets
Save your favorite combinations and start them again with a single tap.

■ Gentle alarms
Wake up to soft chimes, birdsong, or a temple bell — never a jarring sound.

■ Baby Mode (for caregivers)
A safe mode for parents and caregivers to help infants sleep. Curated with sounds that are gentle on developing ears — white, pink, brown noise, lullabies, and womb sounds.

■ Simple by design
· No sign-up, no account, no clutter
· All data stays on your device
· Start using it the moment you open it

■ Notes
DimDim is not a medical device and is not intended to diagnose, treat, or prevent any condition. The effects of frequencies are not medically established and may offer subjective relaxation only. If you suspect a sleep disorder, please consult a healthcare professional.

Do not use while driving or operating machinery. Listen at moderate volumes. Infant auditory systems are highly sensitive — when using Baby Mode, place the device at least 2 meters (7 feet) away and keep volume below 50 dB.
