Elite Viber — Dual N-Back

Elite Viber is a science-backed Dual N-Back brain training app designed for people who take their cognitive performance seriously. Dual N-Back is one of the most researched cognitive training methods in existence. Studies suggest consistent practice improves working memory — your brain's ability to hold and process information in real time — which underpins focus, problem solving and fluid intelligence. HOW IT WORKS A 3x3 grid lights up and a letter is spoken aloud each round. Your job is to remember both the position and the letter from N turns back. When the current position or letter matches what appeared N turns ago, tap the corresponding button. Simple to learn. Genuinely challenging to master. WHAT MAKES ELITE VIBER DIFFERENT Most Dual N-Back apps have a flawed algorithm — once a cell lights up, it appears again more than it should, making the game feel repetitive and defeating the scientific purpose. Elite Viber uses a mathematically correct sequence generator with pre-planned match rates, true uniform cell distribution and anti-lure protection. Every session is a fair, genuine cognitive workout. FEATURES — Dual N-Back at N-2 level — Mathematically fair sequence algorithm — Real-time Position and Sound accuracy tracking — Full session results with combined score — Round-by-round detailed history — Correct, incorrect and missed breakdown — Daily training streak tracking — Personalised daily reminders — Silent mode for training anywhere — Haptic feedback — Export your session history — Built for all modern iPhones BUILT FOR INTELLIGENCE Elite Viber is not a game.
