Most free IQ tests hand you a number and nothing else — and usually an inflated one. This gives you an honest estimate in 5 minutes, plus a radar chart of five cognitive strengths: pattern, numerical, spatial, logic, and memory. Two people can both score 108 and think in completely different ways. That shape is the part worth knowing. Every question comes with a full explanation, so you can check the reasoning behind your score. Free, offline, no account, 17 languages.
