Dual N Back
Science-backed brain trainer for memory and focus.
I built Dual N Back because I wanted a simple way to train my working memory and see whether I was actually improving. Most trainers I tried felt outdated, repetitive, or showed too little progress data. So I created a free web-based trainer with adaptive difficulty, detailed analytics, customizable sessions, daily goals, and reminders. No installation required. The product is still evolving, and I’d love your feedback.
Hey Product Hunt! 👋
I'm Yan, the maker of Dual N Back.
I started this project because I wanted to improve my working memory and focus.
I tried several Dual N-Back trainers, but I kept running into the same problems: outdated interfaces, repetitive training sessions, and very little insight into whether I was actually improving.
So I decided to build the trainer I wanted to use myself.
The project started as a much simpler tool, but while using it, I realized that effective training needed more than just showing sequences and counting correct answers.
I wanted to see my progress over time.
I wanted the difficulty to adjust as I improved.
And I wanted to be able to train from any device without installing anything.
That's how Dual N Back became a web app with adaptive difficulty, performance analytics, customizable training sessions, daily goals, and reminders.
I'm still actively improving the product, and there's a lot I want to add.
And that's one of the reasons why I'm launching here.
I'd really like to hear from people who train their memory, use brain-training apps, or are simply interested in improving focus and cognitive performance.
What would make a tool like this genuinely useful enough for you to want to use it every day?
I'll be here all day answering questions and carefully reading your feedback and suggestions.
Thanks for checking out Dual N Back! 🙌
How does the adaptive difficulty decide when to bump up or down, and does it lean on any published n-back research for the pacing?
Tried it for a few rounds and the adaptive difficulty feels really well tuned. Also appreciate that it runs right in the browser without any setup.
How does the adaptive difficulty actually work under the hood, like does it adjust based on real-time accuracy or some other metric you track?
Nice to see a free option for this. How does the adaptive difficulty actually decide when to bump the level up or down during a session?
