Dojii is the gym for your mind. Take a short assessment, earn your first belt, then train a few minutes a day to climb from White Belt to Black Belt. Six domains. Six games. One scroll that tracks exactly how sharp you're getting. HOW IT WORKS 1. Assess - three quick trials place you on the belt ladder and reveal your starting Ki. 2. Train - a daily plan picks the games that target your weakest domains. 3. Rank up - every session grades your performance and moves your Ki. Earn enough and you take the next belt. SIX DOMAINS. SIX SENSEIS. Each domain has its own game and its own sensei waiting in the dojo: - Recall (Memory): hold the pattern, then find it in the dark - Cipher (Reasoning): crack the code by deduction alone - Ascent (Speed): stack and drop under pressure for combos - Scribe (Language): pull letters from the ring to build words - Reflex (Focus): react to the color, not the direction - Trace (Spatial): connect every pair without crossing a line EARN KI. CLIMB THE BELTS. Ki is what you earn for training above your level, and what you lose for coasting. Eleven belts stand between White and Black, and none of them are handed out. Your rank is what your last session says it is. WHAT'S INSIDE - A daily workout built around your goals, not a generic playlist - Difficulty that adapts to you every single round - Belt ranks and Ki for every domain plus an overall rank - Percentile scores so you know where you actually place - Streaks and rhythm tracking to protect the habit - A dojo island to explore as you unlock each training ground - Sessions short enough to finish before your coffee cools BUILT FOR Students who need focus that lasts past the first hour. Professionals carrying too many tabs. Anyone who wants to keep their mind fast and would rather earn it than be told it's fine. DOJII Premium Dojii Premium unlocks unlimited training across all six domains, your full belt breakdown, detailed progress history, and every dojo on the island. - Weekly, and yearly plans available - Payment is charged to your Apple Account at confirmation of purchase - Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period - Manage or cancel anytime in your Apple Account settings - Any unused portion of a free trial is forfeited when you subscribe Terms of Use: https://dojii.vercel.app/tos Privacy Policy: https://dojii.vercel.app/privacy Step into the dojo.
