Brainrot: Memory & Brain Games
Dual N-Back Focus Training
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Swap a scroll for a session. Match what came N steps back, hold up to four streams at once, and keep your streak on a training calendar. No ads, no feed.
Call it brainrot: that feeling after an hour of short videos, when a single thought won't stay put. Your attention isn't broken — it's just out of practice. This is the gym for it.
Brainrot is a focused N-Back trainer — brain games for memory and concentration, built on one of the most widely used working-memory tasks in cognitive science research. No feeds, no ads, no dopamine slot machine — just you and one demanding task, one rep at a time.
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
• N from 1 to 7, on a 1x3 or 3x3 grid
• Mix visual and audio streams freely — 230+ combinations
• Optional auto-adjust: N rises or drops by thresholds you set
• Two separate audio streams at once, one per ear — put your headphones on for a true dual-sound challenge
• A How to Play guide for every mode
ON MAC, IPAD AND IPHONE — BUILT FOR THE KEYBOARD
• Runs on Mac, iPad, and iPhone — train on the big screen at your desk
• Full hardware-keyboard play on iPad and Mac: 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

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.
