Brainrot: N back Memory Fix

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

• iCloud sync for settings and history across your Apple devices
• Available in 12 languages

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.
