Lumosity Brain Trainer is the first mobile brain training application that integrates with a complete brain training system. Users can train on the iPhone, playing the same games that are available on the website Lumosity.com.  Their progress is tracked using a system — the Brain Performance Index (BPI) — that combines performance on the iPhone and web versions to give an integrated assessment of brain function improvement. Now, users can train their brains at home on their computers or on the go on their iPhones, and the results are tracked seamlessly across platforms.  This app is a result of years long collaboration between Lumosity and the world’s leading neuroscientists from top universities.
