Brain N-Back Premium

Dual N-Back has been shown to improve working memory and fluid intelligence, which is crucial for academic and professional success.

This is a simple clone of Brain Workshop http://brainworkshop.sourceforge.net/ , supporting arbitrary combinations of (position,sound,color,image).

If you rate me less than 5 stars, consider leaving a comment. I've always tried to improve the app according to users' comments ^^

Differences between this version and the Free one:
* No ads, no need for special permissions (Internet, Billing, etc.)
* More responsive on low-end devices due to fewer elements on screens
* More stable for not having to load ads
* More features/settings in the future. The free version will only receive bug fixes, but not more new features.
