Store description excerpt
Your brain has a limit: how much it can hold in mind at once. Dual N-Back is the most studied exercise for pushing that limit. WHAT'S FREE The whole Cognitive Lab, with no limit: all 12 tests, chimp memory, Stroop, reaction time. Your complete training history. And three Dual N-Back sessions a day, at N-1 and N-2. This app is built around that single exercise — not a pile of mini-games that mostly make you good at mini-games. HOW IT WORKS Two streams arrive at the same time: a position on a grid, a spoken letter. You decide whether what you're getting now matches what appeared N turns earlier. You start at N-1. Hit 80% accuracy and the next level opens. It's hard from the first minute. That's precisely why it works. UP TO SEVEN SIMULTANEOUS STREAMS • Dual — position + audio • Triple — colour joins • Quad — then shape • Penta, Hexa, Hepta — up to seven streams at once Levels N-1 through N-15. THE COGNITIVE LAB Short tests that measure something other than working memory: chimp memory, reaction time, Stroop, visual memory, sequences. Each keeps your best. YOUR NUMBERS, NOT BADGES Progress per level, accuracy broken out per stream, average reaction time, streaks. You see where you stall, not just a score. DUAL N BACK PRO • Every level, N-3 through N-15 • Triple, Quad, Penta, Hexa, Hepta • Unlimited daily sessions • Full analytics • Custom Mode and Free Mode 7 days free on the yearly plan. Lifetime available as a single payment. ON THE SCIENCE Dual N-Back is the most studied working-memory task since Jaeggi's 2008 work. Transfer to fluid intelligence is still debated in the literature. What is measurable: your progress on the task itself, and it's on screen. SUBSCRIPTION Payment is charged to your Apple account at confirmation.
