NU._.IRA Alert

Are you as sharp as you feel?

A readiness check measures reaction time and attention, and reads them against your sleep. Try a shortened version here, in your browser, with no sign up.

The demonstration

About 90 seconds.

Four questions about your sleep, a 60 second reaction test, and a 30 second colour-word test. At the end you get a score out of 100 and the reasons behind it.

The full check inside the app takes about three minutes and includes more than this.

Nothing you enter here is saved or sent anywhere. It runs in your browser and disappears when you close the tab.

In the app

The full check takes about three minutes.

The demonstration above is the short version of it, and it is missing the part that makes a readiness check worth doing: knowing what you look like on a good day.

Your own rested normal

After your first few checks it knows what you look like rested, and scores you against that instead of against a population average.

Sleep and recovery from the Band

No typing. Sleep, strain and recovery are read from the Band and folded into the same score.

A third task

A short reasoning task sits alongside the reaction and colour-word tests, so the score reads more than speed.

Your history

One check tells you about today. A run of them tells you what your week of shifts is doing to you.

Built for people who work shifts.

Tiredness is a poor judge of itself. The point of a check like this is that it does not ask how alert you feel, it measures something and tells you what it found, so you can decide what to do with the rest of your day.
