What the tests measure, how scoring works, and what happens to your data.
About IQ tests
An IQ (Intelligence Quotient) test is a standardised way of measuring certain cognitive abilities — logical reasoning, problem solving, pattern recognition and abstract thinking. The first version was developed by Alfred Binet in 1905.
The average score is set at 100. Roughly speaking: 90–109 is average, 110–119 above average, 120–129 high, and 130+ is often described as gifted. About 68% of people score between 85 and 115.
Scores follow a normal distribution with a mean of 100 and a standard deviation of 15. Your raw number of correct answers is converted onto that scale, adjusted for the difficulty of the questions you saw.
TopIQ measures six areas: logical reasoning, numeric ability, verbal comprehension, spatial reasoning, working memory and processing speed. You get a separate score for each.
The questions are built on established test methodology, but any single test is only a snapshot. Results move with sleep, mood, distraction and practice, and no online test replaces a supervised professional assessment.
Using the app
TopIQ is a mobile app for IQ and EQ testing. It gives you timed tests, a per-category breakdown of your results, an explanation for every question, a progress chart and a leaderboard.
Yes. Signing in, taking tests, reading your breakdown and downloading a certificate are all free, with no ads and no hidden charges.
With one tap using your Google account. There is no separate password to create and no form to fill in.
As often as you like. Every attempt is stored, which is what makes the progress chart useful — you can see whether repeated practice is actually moving your score.
Yes. After finishing a test you can download a PDF certificate with your score. It is a personal keepsake, not an academic credential.
iPhone and iPad on iOS 15 or later, and Android phones and tablets on Android 8.0 or later.
Improving your score
Your underlying reasoning ability is fairly stable, but test performance improves with familiarity: knowing the question formats, managing your time and staying calm all help. Expect modest, real gains rather than dramatic jumps.
Sleep, no distractions, and reading each question fully before answering. Rushing the first few questions is the most common way people lose points.
Partly. You will get faster at the formats you have seen, which is why the app tracks each attempt separately instead of averaging everything into one figure.
