iChess is a chess puzzle app available for iPhone users. It offers a collection of 1000 offline puzzles from real FIDE tournament games, making it an ideal way to practice chess without the need for an opponent or a live game.

The app features three difficulty levels, allowing users to choose puzzles that match their skill level. All puzzles can be solved offline, without the need for an internet connection. Users also have the option to load their own PGN puzzle files, allowing them to practice openings or study famous games.

iChess includes a Bird View feature that allows users to view puzzles they have solved, failed, or have yet to see. A scorecard is also available to track progress. For those who want to analyze puzzles, the app offers integration with a separate Chess Engine app.

It's important to note that iChess is not an app for playing chess online or against the mobile or friends. The puzzles are arranged in increasing order of difficulty, and not all puzzles end in checkmate. The app also provides puzzles from top recent tournament games.

Overall, iChess provides a convenient and accessible way for chess enthusiasts to improve their skills through puzzle-solving. Whether you're a beginner or an advanced player, this app offers a variety of puzzles to challenge and enhance your chess abilities.
