Developer post: free browser-based Dual N-Back trainer — feedback welcome

[Yan Lunin]

Hi everyone,

I’m the developer of a free browser-based Dual N-Back trainer, and I’d appreciate feedback from people who actually practice n-back.

The current version supports position and audio training, levels from 1-back to 6-back, classic and adaptive load, adjustable training profiles, keyboard controls, and local progress analytics. It works without registration, and training data stays on the user’s device.

I’m especially interested in feedback on the adaptive difficulty, training setup, and which statistics are most useful for long-term practice.

You can try it here:

This is a training tool, not a medical device. I’m not claiming that n-back practice increases IQ; my goal is to make practice clear, measurable, and easy to start.

Thanks — criticism and feature suggestions are welcome.

Best regards,
Yan Lunin
