Lumosity’s brain training games for the iPhone and now iPad (the Android version is still under development) are spreading fast, especially among those who believe the app can make them smarter. Chief executive Kunal Sarkar is reluctant to state  that this is definitively the case, but he often describes the Lumosity experience as a “gym for your brain.”
