What is "lumosity"

Lumosity is an online program consisting of games claiming to improve memory, attention, flexibility, speed of processing, and problem solving. Lumosity is the product of Lumos Labs, a brain training and neuroscience research company based in San Francisco, California.

There is limited independent evidence that these games are effective, and the company's claims for them have been found to be misleading by the United States District Court for the Northern District of California.
