Wearable-powered tournament safety where smartwatches monitor fatigue and injury risk in real-time—while an AI 'lighthouse' alerts coaches and parents exactly when a child needs rest.
A 12-year-old's watch vibrates mid-game as the coach's phone lights up: "Grace is at 92% injury risk—she's logged 47 minutes of high-intensity play with only 8 minutes rest. Sub her out now." The parent's app simultaneously shows the same alert with a heatmap of Grace's fatigue building across the tournament, like watching a storm approach on radar.
