Train your working memory with Dual N-Back, the bold, no-nonsense brain training game built on the classic n-back task. Spot when the current stimulus matches the one N steps back. Sounds simple. It isn't. That's the point. Dual N-Back puts three independent streams in front of you: . Position - a square lights up somewhere in a 3x3 grid . Audio - a spoken consonant . Color - the square changes color Toggle the streams on or off to play Single, Dual, or Triple N-back. Match one stream, two, or all three at once and feel your focus and concentration stretch. ADAPTIVE DIFFICULTY THAT KEEPS PACE Following the Jaeggi protocol, the level adapts to you. Hit 80% accuracy and N steps up automatically. Slip below 50% and it eases back down, so you are always working right at the edge of your ability. Prefer to set your own pace? Manual mode locks N exactly where you want it, anywhere from 1 to 9. SEE YOURSELF IMPROVE . Daily streak to keep the habit going . Best N, total sessions, and average accuracy at a glance . Charts for level over time, accuracy per stream, and sessions this week . Per-session results with a balanced-accuracy ring and a full breakdown of hits, misses, and false alarms for every stream MAKE IT YOURS . Set trials per block from 10 to 40 . Adjust speed from 1.5 to 4.0 seconds per stimulus . Toggle haptic feedback . Dark, light, or system theme . Optional on-screen captions for the spoken letters PRIVATE, OFFLINE, FREE . Completely free with no ads . No account, no sign-up, nothing to subscribe to . Works fully offline . All your progress stays on your device THE SCIENCE The n-back task is one of the most studied tools in cognitive psychology. This app is modeled on the dual n-back working memory training used in research by Jaeggi and colleagues, where participants practiced matching two simultaneous streams over repeated sessions. We have kept the protocol faithful, from the adaptive level adjustment to the dual-stream design, so your practice mirrors the method behind the studies. A FOCUSED TRAINING SESSION, NOT A TIME SINK No streaks of pop-ups. No energy meters. No nagging. Just a clean, high-contrast training ground for your mind. Open the app, run a block, and get back to your day. Whether you are a student, a lifelong learner, someone exploring focus and attention exercises, or simply curious how far your working memory can go, Dual N-Back gives you a serious tool with zero clutter. Tap to start your first block and find your N.
