ADHD Tests

Screening tools based on the Adult ADHD Self-Report Scale (ASRS). Used by GPs worldwide as a first-step ADHD indicator.

IQ Tests

Pattern recognition, logical reasoning, and spatial tasks. Short online approximations of formal IQ assessments.

Memory Tests

Assess short-term recall, working memory, and visual-spatial memory. Different conditions affect memory in different ways.

Mental Health

Brain Speed & Reaction

Measure your cognitive processing speed, reaction time, and mental efficiency.

Focus & Attention

Assess attention span, concentration, and sustained focus — relevant for ADHD screening and productivity.

Cognitive & Intelligence

Critical thinking, emotional intelligence, spatial reasoning, and full cognitive ability profiles.

Personality & Behaviour

Discover your personality type, dominant thinking style, and behavioural traits.

Sleep & Lifestyle

Assess how sleep quality, brain fog, and digital habits affect your cognitive performance.

Kids & School

Age-appropriate cognitive and learning assessments for children and parents.

Are these tests accurate?

Our mental health screening tests are built on validated clinical instruments: the PHQ-9 for depression, GAD-7 for anxiety, and ASRS for ADHD — the same tools GPs and psychiatrists use. They are reliable first-step indicators, not a substitute for professional diagnosis. A positive screen means your reported symptoms match clinical criteria for that condition. Discuss results with a doctor. Our IQ and cognitive tests are shorter approximations of formal assessments and should be treated as directional.
