Unlike generic quiz apps that just tell you right or wrong, TestEarth calculates your personal TestEarth Intelligence Score (TIS) — a dynamic 70–160 score that evolves with every quiz you take.
Most apps test one thing. TestEarth tests all six. Your TIS reflects your complete cognitive profile.
Visual sequences, shape matrices, and symbol patterns that test how quickly your brain identifies hidden rules.
From simple arithmetic progressions to Fibonacci, prime numbers, and complex multi-rule sequences.
Analogies, synonyms, antonyms, odd-one-out, and logical word puzzles that test linguistic intelligence.
3D visualization, shape rotation, geometry, and spatial logic used by NASA and top engineering firms.
Memorize sequences, numbers, symbols, and word lists under time pressure — then recall under pressure.
Classic riddles, logic puzzles, and creative thinking challenges that break conventional problem-solving.
TestEarth is designed to be compelling. Five minutes a day is enough to see real improvement within weeks.
Sign up in 60 seconds. 7 days of full access to every category and difficulty level.
Choose from 6 cognitive categories. Select Beginner, Advanced, or Expert based on your confidence.
Answer 10 questions against a live countdown. Speed and accuracy both count toward your score.
Your TestEarth Intelligence Score updates after every quiz. Train daily and watch it rise.

TestEarth isn't gamification. Every element is grounded in how intelligence actually works.
Pattern and spatial questions target fluid intelligence — the capacity to reason in novel situations, independent of acquired knowledge. This is the core of raw cognitive ability.
Reaction time under cognitive load is one of the strongest predictors of general intelligence. Our timer rewards fast, accurate thinking — not just eventually arriving at the right answer.
Daily challenges and progressive difficulty mirror well-established spaced repetition principles. Consistent short sessions produce measurably better cognitive gains than occasional long ones.
The memory category directly trains working memory capacity — the mental workspace used to hold and manipulate information. Working memory improvements transfer across all other cognitive tasks.
The TIS is not a static test result. It is a rolling score that continuously recalibrates as your performance data grows — producing an increasingly accurate and reliable measure over time.
Creative problem-solving activates different neural pathways than analytical reasoning. The lateral thinking category tests your capacity to generate solutions outside of conventional frameworks.
"I've tried Lumosity, BrainHQ, all of them. TestEarth is the first platform that shows me a number that actually means something. Watching my TIS climb from 98 to 119 over six weeks has been genuinely motivating."
"Ten minutes every morning before work. My thinking is sharper, I catch patterns faster in my data analysis, and colleagues have commented on it. The lateral thinking category in particular is exceptional."
"As a medical student I need to memorize and reason under pressure constantly. TestEarth's memory and spatial categories are essentially training for exactly what I do every day. Worth every cent."
