What is a Brain Age Test?
A brain age test measures how efficiently your cognitive functions — reaction speed, working memory, attention, and processing speed — perform compared to different age groups. A 35-year-old who scores like an 18-year-old on a reaction time test is said to have a "brain age" of 18 for that cognitive domain. ZAZAZA calculates your brain age across multiple tests and gives you a globally ranked result you can share with friends.

ZAZAZA offers 20+ free cognitive tests across two categories.
