As answered by people managing DeveloperToolStack and iqtest-me.
iqtest-me's answer:
Individual consumers worldwide — curious adults taking the test for personal insight rather than institutional clients
iqtest-me's answer:
Most free IQ tests inflate scores to drive sharing. IQTest-Me is built around honest, grounded results and a per-domain breakdown so you see your actual cognitive strengths and weaknesses. It's free to take, with an optional $1.99 detailed results unlock — no subscription, no upsell funnel.
iqtest-me's answer:
IQTest-Me was built by an independent founder frustrated by online IQ tests that inflate scores and hide their methodology. The goal was a genuinely honest alternative — one that's transparent about the limits of online testing while still giving a useful, detailed picture of how someone thinks across five cognitive domains.
iqtest-me's answer:
An adaptive IQ test that gives a detailed breakdown across five cognitive domains — logical reasoning, numerical ability, visual-spatial, verbal comprehension, and working memory — rather than a single number. Honest positioning: no inflated scores, no hype, transparent about what the test can and can't measure.
iqtest-me's answer:
Curious adults interested in understanding their own cognition — people who care about cognitive science rather than an ego boost. Broad general audience, skewing toward those who value accuracy and transparency over flashy score inflation.
iqtest-me's answer:
React and Vite on the frontend, deployed on Vercel with Cloudflare for CDN and security. Stripe handles payments, Supabase the backend data, and the test uses adaptive question-selection logic that adjusts difficulty based on performance.
