HumanCalc
Your personal gymnasium for working memory, focus, and mental math.
Dual N-Back
The gold standard for increasing fluid intelligence. Track visual and auditory stimuli simultaneously.
Flash Anzan
High-speed mental arithmetic. Visualize numbers appearing rapidly and calculate the sum instantly.
Number Memory
Test your short-term memory by recalling increasingly long sequences of numbers.
Block Memory
Memorize an evolving pattern of blocks on a grid. A challenging test of visuospatial working memory.
The Science
More than just a game.
This is mental conditioning.
HumanCalc is built on the principles of neuroplasticity. Our tools target the core mechanisms of intelligence, helping you process information faster, focus deeper, and retain complex data longer.
Fluid Intelligence (Gf)
Unlike crystallized intelligence (knowledge), fluid intelligence is the ability to reason and solve novel problems independent of past experience. HumanCalc exercises are designed to expand this raw capacity.
Working Memory
Think of this as your brain's RAM. Increasing your working memory allows you to hold multiple complex variables in your head simultaneously—crucial for programming, mathematics, and strategic thinking.
Progressive Overload
Just like a muscle, the brain adapts to stress. By automatically adjusting difficulty (N-Levels) based on your performance, HumanCalc keeps you at the edge of your ability, triggering growth.
