Stroop Test
Measure your concentration and reaction speed in just 40 seconds. On iPhone the test starts instantly as an App Clip, with no installation.
In the Stroop test a colour word such as “Blue” appears, printed in a different colour. Your task: always tap the colour of the text, not the word you read. That sounds simple, but it puts your brain under surprising strain, because reading and colour recognition work against each other.
Scan the App Clip Code with your iPhone camera to start right away. After 40 seconds you get a short summary with hits, accuracy and your average reaction time.
