📖 Our story
Sports4U started as a small project between fitness enthusiasts who realized that most “calorie burn” estimates were either too generic or hidden behind subscriptions. We built a simple MET-based calculator — then added hydration tools, workout planners, and guides.
Today, we serve thousands of active users monthly. Yet our promise stays the same: honest, science-backed sports tools, 100% free.
