RoyalAce

RoyalAce is an offline poker training companion built for players who want to memorize preflop hand ranges through focused, repeatable, and privacy-conscious practice. The app is centered on one clear skill: preflop range mastery. Instead of presenting casino play, real-money wagering, prizes, deposits, withdrawals, betting advice, or live-table assistance, RoyalAce offers a structured learning workspace where users can study a 13 by 13 starting hand matrix, compare position-based range differences, review missed decisions, and build a more reliable memory of common preflop patterns.

The Home screen gives users a daily crown plan with a clear training mission, current mastery indicators, review counts, and the active local content version. The Range Matrix screen lets users explore every starting hand cell by position and action, including raise, call, jam, and fold categories. This makes the full grid easier to understand because learners can see how a button range differs from an early position range, or how blind defense changes the hands that remain in play. The Position Duel screen adds an overlay view that compares two positions side by side and highlights shared hands, left-only hands, and right-only additions. This visual contrast helps users remember range widening, tighter early position choices, and common defending patterns without relying on unverifiable profit claims.

RoyalAce also includes a spaced review flow for mistake correction. Users answer local range scenarios, receive immediate explanations, and see weak decisions added into a review queue. The Mastery Ledger tracks progress by position and focus tag, including premium hands, broadway hands, suited aces, pair cores, connectors, blind defense, steal candidates, and short stack pressure hands. The app records attempts, response timing, quality score, content version, and review scheduling data locally on the device. Users may export or import a JSON backup through Android's system document picker when they choose, but the app does not require an account, email address, phone number, location, contact access, advertising identifier, broad storage permission, or network connection.

The experience is designed with a premium black and gold visual style called Obsidian Crown. The interface uses large readable cards, clear buttons, high-contrast text, and a stable five-tab structure for Home, Matrix, Duel, Review, and Mastery. The artwork uses a crown and card-training atmosphere as a visual theme for educational card strategy practice, not as a gambling service. The app does not connect to any casino, sportsbook, payment service, betting platform, or backend API. All training content is packaged inside the application and runs fully offline after installation.
