About IQ Test

Published: August 14, 2026 • Reviewed by: APEX Business Systems Ltd. • Editorial Standards

IQ Test is an engaging, transparent cognitive self-insight tool developed by APEX Business Systems Ltd. in Edmonton, Alberta. Our mission is to provide an intellectually honest cognitive assessment that delivers instant, un-paywalled baseline scores and fascinating historical mind matching without subscription traps.

Our mission and principles

We built IQ Test because the online intelligence testing category is crowded with deceptive subscription billing traps, inflated scores, and dishonest clinical claims. We set out to create a cognitive tool that treats users with respect:

Immediate Free Results: Your baseline score and percentile appear immediately when you finish the 16 questions.
No Subscription Traps: Optional detailed reports are one-time, flat-fee purchases ($1.99 to $6.99). We never store credit cards for recurring charges.
Psychometric Honesty: We state clearly that this is an entertainment and self-reflection quiz, not a clinical diagnostic assessment.
Meaningful Historical Matching: We connect your cognitive balance to the documented reasoning habits of history's greatest thinkers.
