Whats Your IQ (styled What’s Your IQ) is a free, multilingual cognitive platform developed by Kalenux that combines an IQ test with cognitive subscores, brain-training games, reasoning puzzles, specialised tests and a research library.[1] Its main test has 60 questions, takes about 30 minutes and reports an overall score on the standard 100-mean scale, a percentile and four domain subscores, with no sign-up, email or paywall.[2] The platform is available in nine languages.[2]
1Overview
Whats Your IQ is a cognitive intelligence platform built around four connected experiences: test, train, solve and learn. It starts with an IQ assessment that gives users an overall score, percentile context and separate cognitive subscores instead of reducing everything to a single number.[1]
From there, users can explore brain-training games, practise reasoning questions, take specialised assessments, work through visual puzzles, and read research-backed guides about intelligence, memory, attention, learning, personality, career fit and cognitive performance: all in nine languages. The loop is simple: test, train, solve, learn, repeat.[1]

2History and motivation
Kalenux built the platform in response to IQ sites that, in its words, “stop at the most interesting part”: they ask a few questions, show a number and leave the user with no real understanding of what happened. Some hide the result behind a paywall; others turn intelligence into a cheap quiz. Almost none give a complete path from measurement to improvement.[1]
“The goal is not only to answer ‘What is my IQ?’ The better question is: ‘How does my mind work, and how can I understand it better?’”[1]
3The IQ test
Users pick one of three lengths, answer at their own pace, and read a breakdown. There are no personality questions or filler items.[2]

Get the feel before the full test
Each item has a two-minute soft cap; users can skip and return, and progress auto-saves locally. Difficulty ramps up based on previous answers. The result page shows the overall IQ, a percentile against research norms and the score in each domain, and lives at a unique URL the user can save, share or close.[2]
Sample item
An example from the logical-reasoning subscale asks which number comes next in the sequence 2, 6, 12, 20, … with options 24, 28, 30 and 32. Sample questions are drawn from the same item bank as the real test and show a worked explanation after answering.[2]
4Scoring and methodology
The test uses adaptive, item-response-theory (IRT) scoring: the harder the question answered correctly, the more it counts, with per-item calibration and maximum-likelihood estimation.[2] Results are placed on the standard IQ scale with a mean of 100 and a standard deviation of 15, so roughly two thirds of people score between 85 and 115 and a score of 130 marks about the top 2%.[2]
Domain
What it measures
Verbal reasoning
Understanding and reasoning with words and concepts
Spatial reasoning
Visualising and manipulating shapes and patterns
Logical & abstract reasoning
Rules, sequences and abstract relationships
Working memory
Holding and manipulating information over short periods
Beyond static research norms, results also show a live community percentile against people who took the test recently. The full methodology is published on the site.[2][3]

The site states that it is an educational estimate rather than a clinical diagnostic, and that a well-designed online test typically lands within about 5 to 10 points of a longer proctored test when taken rested and free of distractions.[2][6]
5Brain training
After the test, users can train weaker domains with short cognitive games across nine domains, each with its own scoring rubric and live percentile ranking. Sessions last 5–15 minutes.[2] Kalenux lists 41 exercises; the site describes 40 games.[1][2]

7Puzzles, research and learning
A library of 114 IQ questions and visual reasoning puzzles is available outside the formal test. A research index covers 101 studies, and a learning hub has guides on intelligence, brain training, cognitive psychology, IQ testing, memory, neuroscience and learning strategies.[1]
Other resources include a blog, a books list, GPA and statistics calculators, published editorial standards and an archive on historical IQ tests such as the original Stanford–Binet and Army Alpha.[2][6][7]
8Languages and access
The full experience, tests, training, puzzles and articles, is available in nine languages, using the same items and scoring in each. A full test can be taken without an account; an account is only needed to track progress.[1][2]
The service is free and supported by advertising through Google AdSense, with a cookie-consent system covering essential, analytics and advertising cookies.[8]
9Reception
On the Kalenux product page, Whats Your IQ holds an average rating of 4.6 from 29 moderated user reviews.[9] The site reports more than 5,000 tests completed.[2]
Honest about not being clinical assessment★★★★★
“The site is upfront that this is an educational estimate not a clinical diagnostic. As a psychologist I appreciate that integrity. So many online tests overclaim. This one does not.”
Henrik Olsen, Oslo, Norway · June 2026
Took it in 4 languages, results were consistent★★★★★
“Out of curiosity I took the test in Turkish, English, German, and Russian. Got similar scores each time which suggests the localization preserves item difficulty properly. Solid psychometric work.”
Ekrem Yilmaz, Ankara, Turkey · June 2026
Recommended this to my students★★★★★
“I teach undergraduate psychology and this is the best free online IQ test I have found to use as a teaching demonstration of cognitive assessment design. Item quality is academic-grade.”
