Soccer Referee Timer by WTSB turns Apple Watch into a powerful tool for soccer referees. You do not need your iPhone during the match: manage match time, stoppage time, goals, cards, temporary dismissals, substitutions and penalty shootouts directly from your wrist. After the final whistle, the match is saved and transferred automatically to your iPhone. TIME AND EVENTS UNDER CONTROL The flexible match timer supports one to four periods, countdown or open-ended timing, and customizable match and break lengths. When play is delayed by an injury, goal celebration or another interruption, the app measures the lost time and calculates your recommended stoppage time. Clear haptic alerts notify you when regulation time ends, calculated stoppage time is reached, the break is over or a temporary dismissal has expired – so your attention can remain on the match. Record goals with scorer, penalty or own-goal details, yellow, second-yellow and red cards with reasons, disciplinary action against team officials, and multiple simultaneous temporary dismissals. Custom card reasons can be prepared in advance. Manage lineups, captains and goalkeepers, multiple substitutions, return substitutions and late roster additions, as well as extra time and penalty shootouts. Short voice notes can be attached to cards and temporary dismissals directly from the watch. Match suspensions and abandoned matches are documented too. THE COMPLETE MATCH REPORT The live match report presents every event chronologically and can be reviewed on Apple Watch. On iPhone, it becomes a clear, color-coded report containing halftime and final scores, stoppage time, goals, cards, substitutions, lineups, voice notes and shootout results. Events can be added, corrected or removed after the match, with the score and statistics updating automatically. FITNESS, MOVEMENT AND AI ANALYSIS With fitness and location tracking enabled, a workout starts automatically at kickoff. Apple Watch records heart rate, distance, speed, running power and active calories and saves the workout to Apple Health. The app can also capture the venue, weather and GPS route. On iPhone, explore your movement on an interactive map with route playback, heatmap, detected movement corridor, event locations and sprint analysis. AI-assisted performance analysis combines your fitness data into a Performance Score and visualizes activity, explosiveness and fatigue throughout the match. Compare each performance with previous matches, identify peak-load phases and track your development. The dashboard summarizes your entire refereeing career, including matches, time on the field, goals, cards, stoppage time, distance, venues, speed and performance. SHARE AND CONNECT Share match reports, workout data, heatmaps and sprints as ready-made story graphics. Relive your season with Season Replay and create a personalized referee trading card. Matches can also be uploaded to Strava. Lineup links import rosters and match formats from supported competition software, while the AI Help Chat answers questions about the app and the Laws of the Game with source references. Complications and the Apple Watch Ultra Action Button provide fast access, while an iPhone widget displays key career statistics on your Home Screen. START FOR FREE The free download includes the complete match timer with stoppage-time calculation, haptic alerts, scorekeeping and synchronization. Advanced match documentation, tracking and analysis are available with Pro. Pro can be tested free of charge and unlocked through a subscription or a one-time lifetime purchase.
