Cue · Reaction-time game

Need help with Cue? Most questions are answered below. If yours isn't, write to us directly — we read every message.

How Cue works

Stare at the cross in the middle of the screen. An arrow flashes left or right. A teal dot then appears inside one of the two boxes — tap that box as fast as you can. Sometimes the arrow points the right way. Sometimes it lies. That mismatch is the whole point: it's how psychologists have measured attention orienting for decades.

A session is 40 trials and runs about two minutes. At the end you get a Focus score from 0 to 100, plus the honest scientific number underneath — the "validity effect", the difference in milliseconds between your speed on accurate-cue trials and misleading-cue trials.

What Cue does not do

Cue measures your performance on this task. It does not, and we do not claim, make you smarter, sharper, more attentive, more focused, or better at school, work, driving, sports, or anything else in daily life. It's a small game with a real paradigm underneath. If you enjoy the act of playing and watching your scores, that's the whole product.

Frequently asked questions

What's the Focus score?

A 0–100 number computed from your mean reaction time and accuracy on hits. Lower RT and higher accuracy → higher score. It only describes your performance on this specific task, not your real-world attention.

What's the "validity effect" line at the end?

The scientific readout. It's how many milliseconds faster you reacted when the arrow cued the correct side versus the wrong side. A positive number means you benefited from the cue (most people do). It's not a score — it's just a measurement.

Why is the arrow sometimes wrong?

On purpose. The whole experiment is about how attention shifts: when the cue is accurate, you react faster; when it isn't, you have to reorient, which takes a few dozen milliseconds. Without the misleading trials, there's nothing to measure.

How many sessions can I play for free?

Three full sessions, plus a 6-trial warm-up the very first time you launch the app. After that the in-app unlock is a one-time $1.99 — no subscription — and sessions become unlimited.

How do I restore my purchase?

Tap the paywall and choose Restore purchases at the bottom. Make sure you're signed in to the same Apple ID you used to buy. If it still doesn't restore, email us and we'll sort it.

Does Cue work offline?

Yes. Cue doesn't talk to any server. Once installed, it never makes a network request. All scoring and history happens on your phone.

Are my scores private?

Completely. Your sessions are stored on your device only and are never uploaded, shared, or analyzed by us. We have no accounts, no analytics, no third-party SDKs. See the Privacy Policy for the full breakdown.

Where can I see my history?

Home shows your last seven scores as a small inline trend, plus your current daily streak and your best Focus score. There's no separate history screen on purpose — Cue is a play-the-task app, not a quantified-self dashboard.

How do I uninstall?

Touch and hold the Cue icon on your home screen, choose Remove App, then Delete App. Your scores live only on your device, so removing the app removes them.

I want to share my score.

On the results screen, tap Share. Cue renders a small card with your Focus score and the validity-effect line that you can post anywhere.

Feature request?

Same email. Cue is deliberately small — one verb, one paradigm, one score — so not every request becomes a feature. But every message is read and they shape the roadmap.

Cue measures your performance on the Posner cueing task. It's a game and makes no claim to improve attention, focus, or cognition in everyday life.
