IQ Test Challenge
Brain Training & Real IQ Score
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: exam simulation for aptitude tests and entrance exams – 21 tasks, 20 minutes, with error analysis. Plus the IQ test and a comparison with everyone.
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.
