User Reviews

Great for improving working memory. I liked it so much I upgraded to the paid version for more of a challenge. It was only $1.99 so why not!

This is hands down the best n-back app for iOS. Scientifically proven to improve working memory, and it's completely free. This app is terrific in its simplicity.
