Brainrot: N back Memory Fix

The opposite of doomscrolling. Single-to-Quad N-Back that rebuilds focus and working memory — now on Mac with full keyboard play. Offline, zero ads.

Your attention isn't broken — it's just out of practice. This is the gym for it.

Brainrot is a focused N-Back trainer built on the most studied working memory task in cognitive science. No feeds, no ads, no dopamine slot machine — just you and the rep that rebuilds your concentration.

HOW IT WORKS You watch a stream of stimuli and respond when the current one matches what appeared N steps earlier. In 2-back, you match the item from two steps ago. Simple to learn, genuinely demanding to hold — and that gap is where working memory gets trained.

ONE TASK, ENDLESS DEPTH • Single, Dual, Triple, and Quad N-Back (1 to 4 streams at once) • Stimuli: numbers, letters, sounds, shapes, colors, grid cell position • 1x3 and 3x3 grid patterns • Mix visual and audio streams freely — 150+ combinations • Adaptive N-level that raises and lowers difficulty according to rules you customize • Two separate audio streams at once, one per ear — put your headphones on for a true dual-sound challenge

NOW ON MAC — AND BUILT FOR THE KEYBOARD • Runs on Mac, iPad, and iPhone — train on the big screen at your desk • Full hardware-keyboard play: press Space to start or stop, and H / J / K / L to answer each stream • A built-in Keyboard Shortcuts guide keeps every key one glance away • Ideal for fast, heads-down Quad sessions — hands on the keys, eyes on the streams

TRACK REAL PROGRESS • Per-stream scoring: correct, missed, incorrect • Instant feedback on wrong taps, with optional haptics • Session results after every round • Daily goals to keep the habit • Full training history

BUILT TO RESPECT YOUR FOCUS • Fully offline — train anywhere, no connection needed • Zero ads. Ever. • Clean, distraction-free interface • Light, dark, and auto themes • iCloud sync for settings and history across your Apple devices • Available in 12 languages • Full tablet, Mac, and landscape support

THE HONEST PART N-Back is real cognitive training, not a magic pill. We don't promise IQ points or medical outcomes. It's a serious, well-built tool — the results come from showing up and doing the reps.

Put the phone to work for once. Start with Single N-Back, then build toward Quad at your pace. If you want a particular feature please reach out.

Focus is a skill. Train it.
