## What is Quiet?

Walk your home. Your iPhone builds a 3D map of it, with every sound painted on.

Quiet uses your iPhone's LiDAR scanner to build a live 3D dollhouse of your home as you walk through it. While you walk, it listens for loudness and paints the floor of every room with the noise it heard. Cool blue where it's quiet. Hot where it's loud. A picture of your home you've never seen before.

WHAT YOU GET FOR FREE
• Scan your home in 3D with LiDAR in one walk-through
• See a noise heatmap painted onto your dollhouse, room by room
• Switch heatmap themes, including "floor is lava" mode
• A Quiet Score for every room and one for your whole home
• Rename rooms and spin the dollhouse to any angle
• Share an image or a spinning video of your map
• Two saved scans

WHAT PRO UNLOCKS
• Verdicts: which room is best for sleep, a baby, a home office, or recording, ranked, with the reasons why
• Leak detection: which window or door is letting noise in, and how many decibels louder it is there
• Day vs. night comparison: scan twice, see what changed, room by room
• Unlimited saved scans and a shareable PDF report
• Share your map without the "Made with Quiet" watermark

Quiet Pro costs less per month than most competitors charge per week, and the yearly plan comes with a 3-day free trial, so you can see your whole home mapped before you pay anything.

HOW ACCURATE IS IT?
Quiet's noise readings come from your iPhone's microphone and are meant for comparison (this room versus that one, day versus night), not as a certified sound-level measurement. Quiet is not a medical device and makes no health claims; it's a way to see and understand the sound in your home.

YOUR PRIVACY
Everything happens on your iPhone. There are no accounts, no analytics, and no ads. Quiet never records or stores audio. It only keeps loudness numbers (how loud, never what was said), and they stay on your iPhone. Nothing is ever sold or shared. See the full privacy policy below.

Quiet works on iPhone 12 Pro and later Pro models (LiDAR required).
