Field notes
The app uses its own image code to locate the board and a bundled Core ML model to read the pieces; uncertain squares are marked for correction. It handles some screenshots with evaluation bars, highlighted last moves, and drawn arrows, but the page cautions that textured themes and unusual piece sets may not be recognized. Analysis time is selectable, and the page says certain repeat analyses do not use another analysis.
