N vs Advanced Dual N

Dual N-Back is a scientifically-backed cognitive training game designed to strengthen your working memory and fluid intelligence. First introduced by Wayne Kirchner in 1958 and popularized by Susanne Jaeggi's landmark 2003 research, the N-back task remains one of the most studied tools in cognitive neuroscience. Each round, you're shown a sequence of positions on a grid and hear a sequence of spoken letters. Your goal: identify when either the position or the letter matches what appeared N steps earlier. As your accuracy improves, the game advances your N-level — pushing you further. Game Modes: Dual N-Back lets you track both auditory and visual stimuli simultaneously — the most challenging and most studied mode. Single N-Back focuses on one stimulus type at a time, great for getting started or isolating a weakness. Silent Dual N-Back is visual-only, ideal for quiet environments. Adaptive difficulty adjusts your N-level based on performance. Score history lets you track progress over time. Light and dark mode included. Clean, distraction-free interface built for focus. No ads. No subscriptions. No nonsense. Whether you're a student, professional, or just someone who wants to stay sharp, Dual N-Back gives you a rigorous, research-grounded workout for your mind.

Advanced Dual N-Back is the working memory protocol from the research, built to be done every day: one visual stream, one audio stream, and a level that follows you. Inspired by dual n-back working-memory research, including Jaeggi et al. (2008). HOW IT WORKS In each session, a sequence of positions and sounds is presented simultaneously. Your task: identify when the current stimulus matches the one from N steps back. As you improve, N increases, keeping you always at the edge of your capacity.

No internet connection required • Premium features available through an optional one-time in-app purchase. No subscription • Clean, distraction-free interface THE SCIENCE Working memory is the mental workspace your brain uses to hold and manipulate information in real time. This app provides structured working-memory practice. It does not diagnose or treat a medical condition or guarantee improvements in intelligence. You start at 2-back, the level the original study used, after a short tutorial that teaches one stream at a time. Most people aim for 3 to 5 with consistent training.
