Brainy is a focus trainer built on Schulte tables — it turns three minutes a day into a habit of thinking faster. A Schulte table is a classic neuropsychology exercise: numbers or letters are scattered across a grid and you find them in order, as fast as you can. It trains concentration, peripheral vision and visual processing speed — the skills behind faster reading, longer focus and fewer distractions. FOUR MODES • Classic — numbers in ascending order, from 3×3 to 9×9 • Reverse — from highest to lowest, breaks the familiar pattern • Letters — the alphabet instead of numbers, in English and Russian • Gorbov-Schulte — alternate white and red numbers, the ultimate attention-switching workout GROWS WITH YOU • Adaptive difficulty: when a table gets easy, Brainy suggests the next size • Stars for speed and personal records in every mode • Daily goal — choose 5, 10 or 15 minutes and close it every day • Day streaks and reminders at the time you choose, so you keep the rhythm A GAME, NOT A CHORE • Coins and XP for every session • Character collection — unlock new heroes with levels and streaks • Accessory shop: crowns, glasses, capes and effects for your hero • Achievements and a weekly league on Game Center PROGRESS YOU CAN SEE • Charts and best results for every mode and table size • PIN-protected parent dashboard: stats, daily goal, table size, reminders • A progress card you can share HONEST AND CALM • Completely free: every mode, every size, all statistics • No ads, no subscriptions, no in-app purchases • Works offline and collects no analytics Three minutes of Brainy a day — and focus becomes a habit.

Afraid to blow your first deposit? Here it costs nothing: $10,000 in virtual money, a live chart and a review after every answer — where the zone was and why the price went there. WHAT'S INSIDE • 119 lessons from simple to advanced: candles, market structure, levels, Wyckoff, Smart Money • A library of 96 articles and 221 terms, always open when you forget something • A simulator on live quotes: a virtual account, no real money • A trading journal and a review of your own decisions • A test after every level • Five languages in the app: English, Russian, Kazakh, Ukrainian, Uzbek HOW IT WORKS Every exercise is two charts and one question. You choose, the app shows the breakdown. The correct answer is computed in advance on historical data, not made up on the fly. The app remembers where you go wrong most often and brings those topics back. After a week you see not an overall percentage but a specific weak spot. WHY HERE Most learning apps stop at chart patterns and indicators. Here the course goes on to market structure, liquidity and Smart Money, built on the Wyckoff method that dates back to the 1930s. The author has been trading since 2019 and teaches the same system used in the author's own trading. WHAT'S NOT HERE This is an educational app. There is no real money, no brokerage accounts, no order execution and no trading signals. The simulator account is virtual; its results are not returns and promise nothing. Trading financial markets carries a risk of losing money. The app teaches chart analysis and is not investment advice. SUBSCRIPTION Pro and Pro+ are auto-renewable subscriptions for a month or a year. Payment is charged to your Apple ID when you confirm the purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the period. You can manage and cancel it in your Apple ID settings. Terms of Use: https://extremum.kz/terms.html Privacy Policy: https://extremum.kz/privacy.html
