Browser test
Three claps into the laptop or phone microphone. An RT60 estimate, a noise rating and an approximate RoomScore for the room size you pick. Audio never leaves the browser.

Find out why your conference room sounds bad on calls, and what to fix first.
Clap three times. RoomScore measures the echo and the noise in the room, checks them against the target for a room that size, and puts the fixes in order.
On a laptop? Point your iPhone camera at this code to get the app. About ten minutes from scan to score and PDF.
The app needs an iPhone 12 Pro or newer on iOS 17; the Pro models carry the LiDAR sensor. Available in the U.S., Canada, the U.K., and Switzerland. The browser test runs on any device.
What you get
Numbers you can act on, with the room's own target next to them.
-
Echo, against your room's target
RT60 measured from three claps and compared with the target range for the room's volume. 0.8 seconds in a huddle room is a problem; the same number in a boardroom is fine.
-
A noise rating
Ten seconds of the room at rest: the HVAC, the street, the projector fan. Rated against speech level, so you know whether the far end will hear a hum under every call.
-
What to fix first, with sizes
Panels, ceiling, curtains, carpet: the order that matters for this room, and roughly how much treatment moves the number. Then a PDF you can hand to a vendor or a boss.
-
Optional in the app: a coverage walk maps where the room's microphones stop hearing you, and a Zoom call test grades what the far end actually gets (needs a Zoom Rooms system).
Browser test or iPhone app?
Start with whatever is in your hand. Both give you a RoomScore; the app gives you the real room.

A LiDAR scan gives the real room volume, so the target fits the room. Guided claps and a noise test, an AI check of the microphones and speakers, and a PDF report.

Each clap is a short burst of sound; the room takes a moment to swallow it. RoomScore records that decay and fits it the way acoustic meters do (the T20 and T30 methods), then reports the time it would take the sound to fall by 60 decibels. That is RT60, the standard number for echo.
A clap that clips the microphone or decays into background noise is rejected on the spot, and you clap again. Three accepted claps make a measurement. Noise is a ten-second level of the room at rest with a check of where the energy sits.
Phone and laptop microphones vary, so this is screening-grade: it tells you which rooms need attention, roughly how much, and whether a fix worked. It is not a certification measurement. What is RT60? · How the score is built

Questions
What devices are supported?
The browser test runs on any laptop or phone with a microphone. The app needs an iPhone 12 Pro or later, or an iPad Pro (2020 or later), on iOS 17 or newer, because the LiDAR sensor measures the room.
How accurate are the measurements?
Screening-grade. Measurements are approximate and depend on the device, the room and your technique. Each clap is checked for clipping and decay fit and rejected if it fails, and you clap again. It tells you which rooms need attention and whether a fix worked; it is not a certification measurement.
What data does RoomScore collect?
The browser test analyzes audio in your browser and never uploads it; adding a measurement to the community dataset is a separate opt-in. The app stores acoustic measurements, room metrics and equipment info; room names and locations stay in your account; photos are used for the AI analysis and deleted from cloud storage after processing. Research contribution is optional. Details in the privacy policy.
Can I use this for acoustic certification?
No. RoomScore is for screening and planning. For certification, use calibrated Class 1 equipment and a licensed acoustical engineer.
Measure the room you are sitting in.
Sixty seconds in the browser for a first read, or ten minutes with the app for the real thing. Both are free.
