ChessBase Mobile

Chess tactics training and online play for serious players — ChessBase Mobile is the complete platform to improve your rating through real competition, tactical mastery, and grandmaster study.

Built by ChessBase, the trusted software behind world champions for over 30 years, this app brings professional-grade tools to your phone. Train your tactical vision with puzzles drawn from actual games, not synthetic drills. Your Elo rating updates after every attempt, reflecting your true skill level without artificial rewards. Watch your progress measured in points that matter.

Compete head-to-head in Puzzle Fight — a real-time 24-puzzle battle where you solve the same positions as your opponent simultaneously. Faster solves and higher accuracy win Elo points in structured competition. Play live Blitz and Rapid games against opponents worldwide with full premove support and a distraction-free interface.

Access the ChessBase Online Database with over 14 million games. Search by player, opening, or position to study how grandmasters handle critical moments. Review endgame structures, track opening trends, and build your knowledge from positions played at the highest level—the same research tool professionals depend on.

Analyse positions using cloud engines including Fritz and Lc0. Free basic Fritz analysis is available immediately; upgrade to scalable cloud servers (Large to Gargantuan) for deeper evaluation. Lc0 delivers neural network analysis for complex positions where classical engines plateau. View evaluation, search depth, and best continuations in the engine panel.

Build your opening repertoire in the cloud with 300 opening overviews to get started. Access live opening statistics for every position and drill your variations across three dedicated practice modes until they're automatic. Your repertoire syncs across all your devices.

Annotate your games and analyses with comments, symbols, variations, arrows, and markings. Save everything to cloud databases that stay synchronised wherever you play. Share positions and complete games via link, image, GIF, FEN, QR code, or PGN format—full compatibility with desktop software.

AI Kibitzer narrates your games and puzzle sessions with personality, weaving in chess history, legend anecdotes, and commentary that feels like coaching from a knowledgeable friend. Audio output is included.

The interface adapts to your preference: choose from multiple board colours and piece sets, toggle between light and dark mode, or sync to your device settings. Available in 27 languages. No ads, no energy systems, no paywalls blocking core features—open ChessBase Mobile, train, and play without interruption.
