Ultra N Back - Brain Training
Boost your working memory!
Free · In‑App Purchases
Ultra N Back (UNB) is an app designed specifically to train working memory through the N-Back task.
Allow me to introduce the features of UNB, which perfectly combine ease of use, sustainability, and fun.
UNB offers three distinctive features:
・Highly customizable training functions
・Visualization of growth records and continuity support
・Community features such as rankings
1. Customizable Training Functions
In UNB, in addition to the conventional N-Back modes that train you to remember “letters” and “positions,” you can also choose modes that require remembering “colors” and “shapes.”
This provides multifaceted and high-load stimulation to the brain, making training more effective.
We also addressed traditional issues with the N-Back task, such as difficulty training in places where sound cannot be played, or the inability to adjust training speed to individual needs.
With UNB, you can toggle letter display ON/OFF and freely adjust training speed to suit your personal preference.
2. Visualization of Growth Records and Continuity Support
The N-Back task is effective when practiced consistently over time.
What matters most in sustaining practice is being able to feel your own progress.
That’s why UNB automatically records the number of problems you solve each day, as well as the exact date you achieved each new N level.
These records are visualized in simple, intuitive graphs, allowing you to easily compare with your past self and feel a stronger sense of growth.
To further support consistency, UNB also features a notification system.
You can set your own daily goal for the number of problems to solve. If you haven’t met your goal by a set time, UNB will remind you with a notification.
As a bonus, notifications include hidden tips about the N-Back task that appear at random—don’t miss them!
3. Community Features such as Rankings
Finding peers who are working on the same challenge is an enjoyable part of learning.
UNB makes this possible with a problem-solving ranking system and easy-to-use sharing features for social media.
In particular, the ranking system doesn’t just show the number of problems solved—it also displays titles that reflect the highest N level each player has achieved.
Discovering that there are players who have mastered higher N levels will surely boost your motivation for N-Back training.
Ultra N Back can truly be called the definitive N-Back training app.
We hope you enjoy the experience!
