BrainHQ is an interactive brain training program built by Posit Science. There are many BrainHQ exercises, separated into six categories: Memory, Attention, Brain Speed, People Skills, Intelligence, and Navigation. 

BrainHQ is designed so that you can spend as little as two minutes to as much time as you like in it at any given time. BrainHQ can choose exercises for you using a Personalized Training feature that assesses your progress. Or, you can chart your own course through the exercises based on your interests!
