Train your brain with BrainHQ from Posit Science—the most rigorous program available for better brain health, and the only one backed by more than 100 scientific papers showing benefits - including the breakthrough NIH-funded ACTIVE study. Now with new features that contribute to your brain fitness success!

 BrainHQ represents the culmination of 30 years of research in neuroscience and brain health. Top scientists from around the world helped to develop and test the BrainHQ exercises. The result: a training system that comprehensively improves brain performance, from the most basic elements of perception through the most complex elements of memory, attention, and cognitive function.

 No other brain fitness program can match BrainHQ in scientific proof. More than 100 publications from independent, randomized controlled trials have shown that the exercises and assessments in BrainHQ drive real change. These changes include: • cognitive improvements, such as better memory and faster processing speed • real-world improvements, including safer driving and improved quality of life • physical brain changes, like healthier white matter and more coordinated neurons. 
 All of this means that BrainHQ works—in laboratory studies, and in the lives of everyday people:

 •"BrainHQ is a no-brainer must-have in my book…This training has expanded my visual, fine-tuned my audio and even my reflexes seem to be getting faster. BrainHQ is fun and gives me the challenges I need to keep my brain working out on a daily basis." - C. MacDonald

 •"Only a few months into the BrainHQ exercises the difference is clear, this isn’t left to speculation, I saw drastic improvements…and my family has noticed a strong improvement." - A. Amitrano

 And leading publications agree: “Our testers concluded that Posit's product—one of the few so far to undergo clinical trials and peer-reviewed research—had the firmest scientific grounding.” - Wall Street Journal
 The BrainHQ app helps you set and achieve your brain training goals—so it not only works, it works for you.
 Each exercise adapts to your performance and gets more challenging as your performance improves, just like a personal trainer for your brain.
 The training is designed to fit into your life: train for just 5 minutes in your spare time, or do a complete workout in an hour. 
BrainHQ is a free download, and includes a free exercise every day.
