IQ MAXX is the daily IQ test + cognitive training app. Take a 27-question multi-domain test in about 15 minutes. Get your score, percentile, and 4-domain cognitive profile. Then train daily across Pattern recognition, Numerical reasoning, Verbal ability, and Memory — and retake the full test every two weeks to see how your score moves. WHAT'S INSIDE — 27-question IQ test across 4 cognitive domains — Your IQ score, percentile, and Gaussian-curve placement — 4-domain cognitive profile: Pattern · Numerical · Verbal · Memory — Daily training rotations to build a streak — Bi-weekly retests to track score growth over time — Progress charts and full session history — Wrong-answer reviews with worked explanations HOW IT WORKS The test uses validated psychometric item types — Raven-style matrix reasoning, digit span, spatial sequence, verbal analogies — the same families used in clinical assessment. Your score is calibrated against the standard normal distribution, with a mean of 100 and σ of 15, using a difficulty-weighted model. After the test, daily training keeps you sharp across all four domains. Bi-weekly retests show how your score actually moves over time. PRIVACY No ads. No third-party trackers. No data sold.

How smart are you – compared to everyone else? IQ Test Challenge is a free IQ test and brain training app with classic intelligence puzzles. After every test you see where you stand among all players. With the Club membership you also see where you stand among people like you, by country, age group, gender and education. THE IQ TEST Ten tasks across the classic categories, getting harder as you go. No time limit – think as long as you like. At the end you review your answers, submit them and see your score, your IQ estimate with its range and your percentile on the distribution curve of all players. Then go through every task with its solution – Club members also get an explanation for each one. SEVEN CATEGORIES OF CLASSIC PUZZLES - Patterns: matrices, figure series - Numbers: number series, number grids - Spatial: cube nets, rotation vs. mirror image - Memory: figure grids, n-back - Logic: syllogisms, seating plans - Words: analogies, odd word out - Speed: symbol search, colour-word test Every puzzle is generated fresh – you will not run out of tasks. EXAM PREPARATION Practise for aptitude tests, employment tests and entrance exams: 21 tasks from all seven categories, 20 minutes, no feedback between the tasks – like a real test. Afterwards the error analysis shows your gaps per category compared with other players, and you train exactly there. One exam per week is included; with the Club membership it is unlimited and comes with your history. A practice simulation, not an official test. BRAIN TRAINING WITH A REAL COMPARISON Brain training that shows you where you really stand: train memory, logic, numbers, patterns, spatial thinking, words and speed, and compare yourself with real players instead of only with your own past scores. The weakness analysis builds a brain training session from your weakest task types. With the Club membership: a training plan with your progress per category and unlimited training. COMPARE YOURSELF The comparison is the heart of the app. See how your result compares with the whole community. With the Club membership you also see how many players solve each task and which answer others picked. Your data stays anonymous: no account, no sign-up, and your profile details are optional. MORE WAYS TO PLAY - Daily challenge: five tasks, the same for everyone in the world, with a daily ranking - Sudden death: one task after another, one mistake ends the run. With leaderboards worldwide, per country and per week (with Club membership) - Duel: challenge friends with a code – same five tasks, who scores more? - Training: brain training for a single category, without a score - Statistics: your strengths and weaknesses per category, history and IQ estimate over all tests FREE, NO ADS The IQ test, brain training and all game modes are free and without ads: three IQ tests on your first day, then one test and one sudden death run per day. The Club membership (monthly or yearly) unlocks more: explanations for every task, up to five IQ tests a day, unlimited sudden death, duels and training, the sudden death leaderboards, how many players solve each task and which answer others picked, your percentile in every comparison group, all details of your past tests and a crown in the rankings – and you support the further development of the app. The subscription renews automatically and can be cancelled at any time in your store account settings. Note: IQ Test Challenge is made for entertainment and self-assessment. It is not a clinical or diagnostic intelligence test.
