is an engaging football analysis tool designed for users who want to examine offside positions using match images and visual reference lines. Users begin by selecting an image and then mark clear field lines to create two reference points. The interface provides Undo, Confirm and Reset controls while keeping the pitch image visible, allowing each part of the setup to be adjusted before completing the analysis.
The application allows users to mark the positions of the defender and attacker after establishing the field references. Once the required points have been placed, the resulting analysis can indicate whether the situation is offside or not offside. The result screen displays the pitch together with coloured guide lines and marked positions, while the New analysis option allows users to start another check. A precision mode helps with more accurate placement, and additional settings allow users to adjust line thickness, dot radius and colours.
In addition to the visual analysis tools, includes an educational section dedicated to explaining the offside rule. Users can explore information about what offside means, when it is called, player position on the field, the moment of the pass and active involvement in play. Additional examples compare offside and not-offside situations while highlighting important elements such as the second-last defender, ball position and the body parts considered when determining a position. The application combines image-based marking, visual reference tools and football rule guidance in one interactive experience.
