Expected Goals (xG) and Expected Goals on Target (xGOT) are the gold standards for modern football analytics. While xG measures the quality of a chance based on the shot's origin, xGOT is the essential metric for a goalkeeper. It evaluates the quality of the shot after it has been struck, accounting for where the ball enters the goal frame.
In this app, we bridge the gap between amateur play and professional-grade data. Most xGOT calculators are locked behind expensive paywalls used by elite clubs and some aren't even accessible at all. By providing a free multi-purpose calculator, we empower local goalkeepers to analyze their shot-stopping performance per game. If a shot has an xGOT of 0.90, it was nearly unstoppable; by tracking these metrics over a season, a goalkeeper can identify how well they've played throughout the season and where their strengths and weaknesses are with the heat map.
Beyond the math, this tool integrates a leaderboard system and performance ratings. This allows for a holistic view of a player's development—tracking not just the 'big saves' but the statistical consistency required to lead a team from the back. Whether you are playing in a local Sunday league or a competitive club, this tool was designed for every keeper to use no matter your level of competition.
xG
Measures chance quality based on shot origin, distance, and angle.
xGOT
Measures post-strike shot quality based on ball placement in the goal frame.
Performance Score
Combines xGOT, saves, goals conceded, and modifiers into a single rating.
ShotTracker lets you place shots on an interactive virtual pitch. For each shot you log the attacker's position, the goalkeeper's position, and where the ball travels — both on the field and on the goal face. The engine then computes xG from spatial data and xGOT from shot placement difficulty, giving you a final performance score for the entire session.
Export each game as a JSON file and load multiple files into the Season Summary tab. The aggregated heat maps reveal shot origin tendencies and goal-face weaknesses across an entire season. The trend graph shows your performance score over time, letting you spot improvement or identify dips in form week by week or month by month.
Submit your best performance scores to the global leaderboard and compare yourself against goalkeepers from around the world. Scores are validated to prevent unrealistic entries, ensuring fair and meaningful competition for all skill levels.
