Great game; has a bug that I can’t report

I like this game a lot. But it has a bug that incorrectly marks some of my actions as incorrect. I have screen captures of this to share, but the developer’s web site is entirely in Japanese.

Response from developer

Thank you for taking the time to report this, and sorry about both the gameplay issue and the difficulty finding a way to contact us. The screen captures would be extremely helpful for our investigation. Please feel free to send them to eigomonogatari@frecre.com. We really appreciate you catching this and being willing to share the details with us. We’ll take a close look at what’s happening.

New Mode suggestion

This app is really great, but I want a mode where only the sound or the visuals play, a mode called single n back

Response from developer

Thank you for the great review and suggestion! 😊 A Single N-Back mode for sound-only or visual-only training is a really useful idea, especially for focused practice. We’re considering this for a future update, so please stay tuned. Thanks again for sharing this with us!

Challenging, and genuinely helpful tool

Dual N-Back can be done by anyone in their head by repeating sound and visuals from a few moments prior, but this is an app that allows you to train your memory In a similar way, and notifies you to stay consistent, it doesn’t flood you with ads and it’s an admirably simple and effective tool that’s does its job efficiently. The only thing is the tutorial for some can be lacking a bit of explanation and detail, I think it would be a bit better if they clarified that each sound and position is one turn (or N=1), and the number N is the amount of turns ago that you’re required to remember and respond to in the current turn.

Response from developer

Thank you for the thoughtful and detailed review! 😊 We’re really happy to hear that you find Dual N-Back effective and helpful for consistent memory training. Your explanation about clarifying each sound/position as one turn, and N as the number of turns back to remember, is very useful. We agree this could make the tutorial easier to understand, especially for new users! We’ll keep this in mind as we improve the onboarding. 🤩

FAQ

What does the Dual N-Back app do?

The Dual N-Back app is a brain game designed to strengthen your working memory. It presents simultaneous audio (letters) and visual (positions) sequences, requiring you to recall information from a specified number of turns back. Consistent play may help improve short-term recall, focus, and concentration.

What are the key features of Dual N-Back?

Key features include customizable settings like the N-value (number of turns to recall), interval between stimuli, and session length. It also offers goal setting with reminders, global leaderboards to compare scores, social sharing options, and multilingual support. A Pro version provides an ad-free experience.

How much does Dual N-Back cost?

The app is free to download and play, but offers an optional 'Dual N-Back Pro' subscription for an ad-free experience. This Pro version includes a 3-day free trial. Payment for the subscription is charged to your iTunes account, and renewals occur within 24 hours before the current period ends. You can cancel anytime.

What is working memory and why train it?

Working memory is the capacity to hold and process information briefly, enabling tasks like decision-making and calculations. Training working memory through games like Dual N-Back can potentially improve focus, concentration, and overall brain agility.

How do I play Dual N-Back?

The game starts at Level N=2, where you must remember the position and sound from two turns ago. If the current stimuli match what was presented two turns prior, you tap the corresponding button. Successful performance increases the difficulty level, but you can also manually adjust it.
