Lumosity bills itself as a “gym for your brain.” Developed by a team of neuroscientists and cognitive psychologists, Lumosity customizes a brain-training schedule for users in five categories: Memory, Attention, Speed, Flexibility, and Problem Solving. Simply download the application onto your iPhone or iPad, register with an e-mail address, and then answer a series of questions to maximize your learning experience. Lumosity compiles users’ statistics into a BPI (Brain Performance Index), and has features that compare your BPI scores with other players.
Compatibility: iPhone and iPad
Cost: Free, but there are options for an extended version of the service that cost $14.95 per month for a Web-broswer version, or $80 a year for the iPhone and iPad app.
