Analyze your games

Analyze your games is a valuable tool for every chess player that needs to know his real play strength. This application compares the moves played in a game with the best moves that a strong engine like Stockfish would do, and it calculates a quality percentage and an approximate ELO rating throughout the game.

It also automatically detects the variation of the opening played, showing in green color the moves pertaining to that opening. The rest of the moves are shown in a color palette ranging from red for blunders to blue for optimal moves, including cyan for sub-optimal moves.

During analysis phase it is possible to interact with the gameboard and the moves, being both parts synchronized by default. At any time the analysis can be interrupted and resumed later on without losing the data. It is also possible to analyze in background or even while screen is off.

Once the analysis phase is over (or even in half-analyzed games), the application shows a briefing of the calculated results, highlighting best moves, blunders and skipped tactics. It also shows ELO and quality graphs in every movement of the game, taking into account that openings are not included in the calculus. By default, movements pertaining to completely lost or win positions are not included in the analysis, because players tend to do safe moves instead of accurate ones in those phases of the game. The analyzed games can be reviewed at any time without the need of a further analysis.

The game tab lets you interact with the chessboard and the moves, and shows the best movement suggested by the engine with an arrow, in order to compare it with the one played by the human. In the initial settings, the analysis mode is selected as faster (5 seconds per move), although you can improve accuracy with 10 seconds per move. It is also feasible to increase the number of threads used by Stockfish up to 8 (by default it is 2), so that your device can get a deeper analysis in the same period of time.
