Dual NBack – Brain Training to Improve Memory Dual NBack is a fun and challenging brain game designed to strengthen your working memory. Set goals, get reminders, and climb the global leaderboards as you sharpen your mind! What Is Dual NBack? Dual NBack is a memory-training game that presents audio (letters) and visual (positions) sequences simultaneously. Research suggests that consistent play may enhance your working memory—the ability to hold and process information briefly—and also boost short-term recall. How to Play The game starts at Level N=2, where you need to remember the position (square) and the sound (letter) from two turns back. If the current position or sound matches what was shown two turns ago, tap the corresponding button. Strong performance automatically raises your level, but you can manually adjust the difficulty whenever you like. Key Features Customizable Settings Tailor your training: tweak the N-value (number of turns to recall), the interval between sounds/blocks, and session length as you see fit. Reminders & Goals Set daily or weekly targets and enable notifications to help you practice consistently. Global Leaderboards Compare your scores with players worldwide and see how you rank as you improve. Share Function Post your results on social media or messaging apps to challenge your friends and family. Multilingual Support Currently offered in English and Japanese, with more languages on the way. Why Train Your Working Memory? Working memory stores information for a few seconds to minutes, enabling you to make decisions, perform calculations, or tackle other cognitive tasks. Playing Dual NBack regularly can help strengthen this mental capacity, potentially improving focus, concentration, and overall brain agility.

Found a bug but good game

On the last level if you restart, the old sequence continues during the new game. This happens around 1/3 of the time. Nothing game changing but hope it gets patched.

*Devs I found a new bug. When I choose the wrong answer the button turns yellow. Then it’s blacked out for a few seconds and I can’t press it again. This is a problem because if the next sound/position is a match I cannot press it and it shows red when I miss it. Even tho I tried to press. The buttons should only turn yellow, red, and green for a second or 2 max so that the button can be ready for next selection right away. Please fix this as well. Thank you! 🙏🏽I love the app. I just hate ads. I know many people don’t mind them, but I abhor them. I really wish the dev would add an option to pay like 1.99 or even 4.99 to support the dev and remove all ads. If you’re reading his dev, I don’t know how many will utilize this feature but you’ll for sure get my money if you add this option. Other than the ads I think it’s one of the best dual N back on the App Store. I love the color scheme and the voice for the letters is clear and easy to differentiate.

The app is good if you are a beginner and start with N=1, 2 or 3. i think what would make it very nice is if you were able to customize the time even further past 60seconds,l; should you go past N=3, at least 3 minutes seems necessary for the full benefit of the game

Sometimes you click "position" but it opens settings istead of making a choice, so you have to play everything again. It's really annoying. This happens once in 3 games or soSometimes it plays two games at once (idk how to reproduce), but it shows two positions at the same time and two sounds instead of one.Can't play, deleting
