Focus at work
Most productivity advice is someone else's routine, generalised. Ninug measures when your attention actually holds, what conditions it holds in, and when you have run out — for you, not for an average person.
The measurement
Nobody concentrates in a flat line. Attention drifts out and comes back, dozens of times an hour. What separates a good working session from a bad one is not peak intensity — it is how often you drift, and how long it takes to return.
So we do not show you a live “focus percentage.” Watching a number like that is itself a distraction, and it turns work into a performance for a sensor. You get the session afterwards:
“You held focus for 41 of 52 minutes, with six drifts — most of them after minute 35.”
What it is for
Everyone has a window where difficult work is genuinely easier. After a few weeks the pattern is unambiguous, and it is frequently not the one you would have guessed. Protecting that window is the highest-leverage change most people can make.
Poorly ventilated rooms measurably degrade cognitive performance, and a closed meeting room with six people in it gets there fast. The Ninug Room sensor makes the effect visible, and the fix is usually free — open a window.
Mental fatigue shows up in the signal before it shows up in how you feel. Knowing you are past the point of useful work is worth more than another hour of pretending otherwise.
The clearest, most repeatable finding in personal data: short nights land in the afternoon, not the morning. Once you can see it, the trade-off you are making at 1am stops being abstract.
Also for
Running the same experiment on yourself for years with no instruments — trying routines, blaming willpower, never knowing which change did anything. Objective session data turns that into something you can actually iterate on. We do not treat ADHD and we do not diagnose it; we measure the conditions under which your attention holds.
Slow eye movements, long closures and head nods are the clearest signals we can read, and they arrive before someone knows they are going. For drivers, operators and clinical night staff, a short-horizon drowsiness warning is a different category of useful.
If your employer buys it
Fatigue management is a real safety need and a real market. It is also the easiest way for a company like ours to end up building surveillance, so the boundary is written into the product rather than the terms of service.
Individual bands ship first. If you run a fleet, a plant or a night-shift operation and want to talk about fatigue monitoring, we would like to hear from you early.
