Brain games for memory & focus: dual N-back working memory training. Zero ads.
Brainrot is a brain games app for memory and focus, built on dual N-back — the working memory training task most studied in cognitive science. Short daily sessions, no feeds, no ads. Your attention isn't broken — it's just out of practice. Brainrot is the gym for it: a focused memory game that swaps the scroll for a few minutes of real brain training. How the N-Back Memory Game Works Watch a stream of stimuli and respond when the current one matches the item from N steps earlier. In 2-back, you match the item from two steps ago. Easy to learn, hard to hold — and that gap is exactly where working memory, concentration and focus get trained. As you improve, N goes up. Brain Training With Endless Depth • Single, Dual, Triple and Quad N-back — 1 to 4 streams at once • Classic dual n-back: grid position plus sound • Stimuli: numbers, letters, sounds, shapes, colors and grid positions • 1x3 and 3x3 grids, 150+ combinations of visual and audio streams • Adaptive difficulty: the N level rises and falls by rules you set • Two audio streams at once, one per ear — a true dual-sound challenge with headphones Track Your Memory and Focus Progress • Scores per stream: correct, missed and incorrect • Instant feedback on wrong taps, with optional haptics • Results after every session and your full training history • Daily goals and streaks that build the habit Back Up Your Progress • Back up and restore to a folder in Google Drive, Dropbox or any storage app • Automatic background sync keeps your settings and history safe • Share a backup file, or restore on a new device anytime • Your backups stay in your storage — never on our servers Built to Protect Your Attention Span • Zero ads, no feeds, no endless scroll • Clean, distraction-free design with light, dark and auto themes • Phones and tablets, portrait and landscape • Available in 12 languages • With Premium, train fully offline Free and Premium • Train free every day • Premium unlocks unlimited sessions Who It's For Anyone who wants a sharper memory and better concentration: students, people whose attention span suffers from short videos and doomscrolling, and brain game fans who want a real challenge beyond puzzles. The Honest Part N-back is real cognitive training, not a magic pill. We don't promise IQ points or medical outcomes — the results come from showing up and doing the reps. Missing a feature?
