What’s New: Major Update: Expanded Language Support! We are thrilled to officially support a total of 7 new languages! You can now experience the app in German, Russian, French, Spanish, Japanese, Chinese, and Portuguese. Every single menu, button, and guide has been meticulously translated and verified for a fully localized experience. Polished UI & Layouts No more broken layouts or cut-off text! We’ve implemented responsive UI fixes across the Home and Settings screens. Even for languages with longer words (like French or German), text will now scale beautifully and fit perfectly within buttons and cards without any wrapping or overlapping.

feat: Revolutionary Play Against AI Mode You can now play directly against our AI anytime, anywhere! This massive update brings a highly flexible and immersive chess experience to your fingertips. 1. Seamlessly Switch to AI at Any Moment While playing a local match (player vs. player) via 'Play Game', you can now seamlessly hand over the opponent's side to the AI at any specific turn. Instantly test how you fare against the engine in complex positions. 2. Choose Your AI Difficulty on the Fly At any point during the game, you can summon an AI opponent tailored perfectly to your skill level. Select the exact strength you want to face, whether you are looking for a casual warm-up or a grueling challenge. 3. Effortless Mode Swapping The control is entirely in your hands. Even after switching to the AI, you can transition back to a human-to-human local match whenever you please, offering complete freedom in how you study and enjoy your games. feat: Advanced Review Features and FSRS-Powered Quizzes We have launched a major update packed with powerful review tools, enhanced AI engine customization, and an intelligent spaced-repetition system to take your training to the next level! 1. Real-Time Move Advantage Graph Visualize the flow of the game at a glance. In Review Mode, we have added a graph that displays the positional advantage or disadvantage for every single move, helping you easily identify critical turning points and blunders. 2. Resume from Any Move in Review Turn analysis into practice instantly. You can now select any specific move during your review and restart the game against the AI from that exact position, allowing you to test out better alternatives in real time. 3. Enhanced AI Engine Stability and Customizable Depth Enjoy a much smoother and more powerful analysis experience. We have significantly improved the stability of our AI engine and introduced a depth-customization feature, letting you adjust the engine's search depth based on your device's hardware specifications. 4. FSRS-Powered Smart Spaced Repetition for Opening Quizzes Never make the same mistake twice. Leveraging the advanced FSRS (Free Spaced Repetition Scheduler) algorithm—similar to Anki—our opening quizzes now track your mistakes and automatically schedule review sessions for the lines you struggle with, ensuring efficient and long-term memory retention.

feat: Chess Opening Guides and Quizzes We have added highly useful opening guides and interactive quizzes to help you elevate your chess game! 1. Comprehensive Opening Guides and Alternatives Master the critical early stages of the game with our new opening tutorials. Instead of just memorizing sequences, you can now explore the strategic meaning behind each move, along with powerful alternative variations for every line. 2. Opening Quizzes for Every Move Put your knowledge to the test with our comprehensive quiz system. We have added dedicated quizzes covering every single move of the major openings, allowing you to practice and perfectly execute your favorite lines in real matches.
