Scientific evidence shows this exercise can significantly boost your working memory.

Working memory is a memory buffer of your brain, responsible for holding and manipulation of information.

Multiple studies suggest that improving brain's working memory increases fluid intelligence. Dual N-Back is the same exact exercise performed by test subjects during experiments.

The app mimics the rules and mechanics of original experiments as close as possible giving you at the same time:
- Competitive features (Game Center and leaderboards)
- Configurable reminders to help you stay on track
- Extensive statistics to analyze your progress

Also, the app requires no internet connection for the most of its features.

What's New

Version 1.3

Brain workout reminders
Dual N-Back is proved to be working only if used consistently. With this release, it has become easy to stay on track — just enable daily reminders in settings.

Simple and elegant. Love it!


The app is simple and uncluttered. The scoring system is also simple to work with. It also keeps track the days trained and has an option to be reminded daily.

Although, I think showing a grid would avoid some of the confusion.

Needs sync between devices


It has a very nice interface. I would prefer that it showed a grid like other versions of this game. It also needs to sync stats and progress via the Game Center.

Pretty good but usability issues


Can’t tell a lot of sounds apart: M and N are the worst, but there are other pairs that are indistinguishable. Also, need a grid. And stats for people who only play one round per day
