What is HoduAtlas?
Hodu is a walnut — its wrinkled shell resembles a brain. Atlas is a book of maps. HoduAtlas measures your brain across 4 domains and returns the results as numeric coordinates. No grand promises about "brain training." Just a clear picture of where you stand.
Why measure?
Without knowing how fast you are, there's no baseline to improve against. Numbers enable comparison, comparison drives retry. One more round, then another. Records stay in your browser only — nothing goes to a server.
Four domains
- Reaction Time — The moment green appears — can your fingers outpace your brain? Five rounds averaged to pin down your reflexes.
- Memory Span — Can you hold a fleeting number in your mind? Find the edge of your working memory as digits grow.
- Arithmetic Speed — 60 seconds — how fast does your mental calculator run? Don't stop when you get one wrong.
- Aim Trainer — The distance between eye and hand. Chase 15 targets to measure your hand-eye coordination.
