Cue: Reaction Time Game
Posner-style reflex test, two minutes per session
Cue is a small reflex game built on the classic Posner spatial-cueing task from attention research. An arrow points left or right — and sometimes it lies. You tap the dot as fast as you can; a session is 40 trials and takes about two minutes.
The app reports a Focus score and validity-effect numbers that describe only your speed and accuracy on this specific task. The developer states plainly that Cue is a game, claims no improvement to attention or memory in everyday life, and is not a medical device. It runs on iPhone, Mac and Apple Vision, is English-only and weighs 1.2 MB. The App Store listing states no data is collected.
Why no subscription? Cue is a one-time $0.99 purchase — “One price, no subscription” — and supports Family Sharing.
