ChessBase Mobile Chess vs Chessigma

ChessBase Mobile is the training, playing, and analysis platform for chess players who track their progress by the numbers. ChessBase Mobile is built by ChessBase, the company behind the standard desktop software used by world champions and club players alike for over 30 years. Solve tactics puzzles rated by difficulty and watch your Elo rise or fall with every attempt. No participation trophies, your rating reflects exactly where you stand. The tactics database draws from positions in real games, not synthetic exercises, so the patterns you train are the patterns you encounter at the board. Puzzle Fight puts you head-to-head against another player in a timed series of 24 tactical positions. Both players solve the same puzzles simultaneously. The one who solves more, faster, wins - and gains Elo. Structured competition, not a casual minigame. Play live games in Blitz and Rapid formats against opponents worldwide. Premove support, clean interface, no clutter. The ChessBase Online Database contains over 14 million games. Search by player, position, or opening. Review grandmaster games, study endgame structures, track opening trends - the same database used by professionals, accessible from your phone. Cloud analysis with several engines, including Fritz and Lc0. Basic cloud analysis with Fritz is free. For deeper analysis, scalable cloud servers are available, from Large to Gargantuan, paid per minute in ducats. Lc0 brings neural network evaluation for positions where classical engines struggle. The engine panel shows evaluation, depth, and principal variation. Build and maintain your opening repertoire in the cloud. 300 opening overviews with repertoire suggestions help you get started with new systems. A live opening book provides up-to-date statistics for every position. Three practice modes let you drill your variations until they stick. Annotate your games with comments, symbols, variations, arrows, and markings. Save games and analyses in cloud databases that synchronise across all your devices. Share positions and games via link, image, GIF, FEN, QR code, or PGN. Upload and download PGN files for full compatibility with desktop software. AI Kibitzer provides live commentary during games and puzzles — with personality. Chess-legend anecdotes, opinions, the occasional bad joke. Like a friend with too much chess trivia sitting next to you. Audio output included. Available in 27 languages. Customisable board colours, piece sets, and notation display. Light and dark mode across all screens, or set to follow your device preference. No ads. No energy systems. No artificial gating. Open the app, train, close the app. Free to use, all functions are available at no cost. ChessBase Premium unlocks expanded cloud storage and unlimited database search results.

Chessigma reviews your chess games, shows you where the points went, and turns your own mistakes into training. The app has five tabs: Home, Train, Coach, Games and Brain. FREE - Game review: import your games from Chess.com or Lichess by username, or paste a PGN or a game link. Every move is graded, the turning points are marked, and you see the better move and the evaluation graph. The Stockfish engine runs on your phone, so a review needs no account. - Scan: pick a screenshot, a photo of a screen or a diagram from a book, and the analysis board opens on that position with the best move. It reads screens and diagrams, not real boards. - Puzzles: a daily puzzle to keep your streak, classic puzzles, and Woodpecker sets that repeat the same positions until the patterns stick. - Opening Trainer: learn opening courses line by line. The first lines of every course are free. - Brain Games: twelve short games with scores and leaderboards. Nine are built on chess, and three need no chess: a reaction time test, Queens and Memory Match. - Sparring: play the first bots on the sparring ladder. - A first look at your player report, built from your recent online games. - One move explanation from the coach each day when you are signed in. Signing in is free and keeps your streak, puzzle rating, scores and progress on every device. SUPERCOACH Supercoach is the paid plan. It adds: - Coach chat: ask the AI coach about your games, your openings and your habits. - Your full player report in six chapters (Overview, Blunders, Clock, Tactics, Conversion, Openings), with a heatmap of your blind spots. - A daily plan of coached tasks picked from your own games. - Move explanations in every game review, and the option to play on from any position. - Blunder Shield and Blunder Training: drills built from the positions where you blundered. - Conversion Trainer: practice winning the games you were winning. - Every rival on the sparring ladder and every line of every opening course. Coach messages come from a monthly allowance. Coach answers are written by an AI model through a third-party service, and every answer has a Report button.
