LIVE · Collective attention meter
Know when you're losing your room. Before you lose it.
No raised hands, no interruptions: each person signals with one tap —“slower”, “I'm lost” or “all good”— and you see the room in aggregate to adjust your pace on the spot.

A silent room doesn't mean they're following you.
Faces don't always tell and nobody interrupts to warn you. Attentiometer gives you the missing signal: the real pulse of your audience, in aggregate and without exposing anyone.

How it works
From doubt to data in three steps
No friction for you or your room. Ready before your talk starts.
-
STEP 01
Create the session
You get a 6-letter code and a QR to project. Your room joins in seconds, with no sign-up or downloads.
-
STEP 02
The room responds
Three buttons on the phone: “slower”, “I'm lost” and “all good”. Signals expire on their own: the panel shows now, not half an hour ago.
-
STEP 03
Adjust on the spot
You see the pulse on a meter and we alert you when your threshold is crossed. You change pace before you lose the room.
Features
Everything you need to read the room
-
Real-time pulse
Every tap reaches your panel instantly, while you speak.
-
Anonymous by default
Nobody is exposed, so people answer honestly. If you need it, nickname mode or class roster.
-
Topic outline
Mark the current topic and you'll know not just that you're losing them, but where: “at backpropagation, not at derivatives”.
-
Attention river
How the room evolved over the session: which moments hooked them and which didn't.
-
Threshold alerts
You decide when to be alerted (e.g. if 10 % are lost). Visual alert and, if you want, a sound.
-
Report when you finish
What to review, peaks per topic and critical moments. Exportable to PDF with your organisation's branding.
The teacher's panel
The whole session at a glance
While you speak, the panel shows the current pulse, how many want it slower or are lost, and the session river with the topic you were on.
