About Dual N-Back: Brain-Training
Dual NBack – Brain Training to Boost Your Memory
Dual NBack is an entertaining and challenging game designed to train your working memory. Stay motivated with daily reminders, personal goals, and global leaderboards as you sharpen your mind and compete with players around the world.
What is Dual NBack?
Dual NBack is a memory-training game that simultaneously presents audio (letters) and visual (positions) sequences. Research suggests that consistent practice with Dual NBack may improve working memory—your ability to hold and process information for short periods—along with short-term recall.
How to Play
The game begins at the default Level N=2.
You must remember the position (square) and the sound (letter) from two turns back.
When the current position or sound matches what was presented two turns ago, tap the corresponding button.
Strong performance will automatically increase your level, though you can also adjust it manually if you prefer.
Key Features
Customisable Settings
Personalise the difficulty by configuring N (number of turns to track), intervals for sounds and blocks, and overall play duration.
Reminders & Goals
Set daily or weekly targets and enable notifications, ensuring you train regularly.
Global Leaderboards
Compare your score with players worldwide and see how you rank on the leaderboards.
Share Function
Share your results with friends or family on social media and encourage them to join you in training.
Multilingual Support
Currently available in English and Japanese, with more languages planned.
Why Train Your Working Memory?
Your working memory holds information briefly (from a few seconds to minutes) so you can make decisions, perform mental calculations, or complete other cognitive tasks. Regular sessions with Dual NBack may help stimulate and enhance this mental capacity, improving focus, concentration, and overall brain agility.
Enjoy an Ad-Free Experience with Dual NBack Pro
Try Dual NBack Pro free for 3 days and train your brain without adverts.
If you opt to purchase Dual NBack Pro, the payment will be charged to your iTunes account.
The subscription renewal fee will be charged within 24 hours before the current period ends.
You can cancel your subscription at any time:
Go to Settings → tap your name → Subscriptions → locate and cancel the one you no longer wish to keep.
If you do not cancel before the 3-day free trial ends, the paid subscription will begin automatically.

About Dual N-Back: Memory Training
Dual NBack – Memory Training & Brain Game
Dual NBack is a fun and challenging brain game designed to improve working memory, focus and mental performance.
Unlike simple brain games, Dual N-back is based on a scientifically studied memory training method that pushes your cognitive limits and adapts as you improve. Set goals, get reminders, and climb the global leaderboards as you sharpen your mind!
What Is Dual NBack?
Dual NBack is an advanced memory training game where you track simultaneously both:
• Visual positions
• Audio letters
Research suggests that consistent play may enhance your working memory—the ability to hold and process information briefly—and also boost short-term recall.

Your task is to detect when the current stimulus matches what appeared N steps earlier.
Start at Level N=2 and train your brain to remember patterns from multiple steps back.
If the current position or sound matches what was shown N turns ago, tap the corresponding button.
As your performance improves, the difficulty increases automatically — making every session both challenging and rewarding.
You can also manually adjust:
• N level
• Speed interval
• Session length
Train at your own pace and build real cognitive endurance.
