Run Smarter with 3D Motion + AI Transform your smartphone into a biomechanics lab. Capture your stride. Analyze your form. Improve with precision. ///Overview/// This app offers full-body 3D motion analysis, AI-based feedback, and even ground reaction force (GRF) estimation — all from a single video recorded on your phone. Whether you're jogging, running, or sprinting, gain deep insights into how you move, where you can improve, and how to train smarter. ///Core Features/// • 3D Running Form Analysis Track your trunk lean, joint angles, stride mechanics, and symmetry — frame by frame. • AI-Powered GRF Vector Estimation Estimate ground reaction force angles and magnitudes with no sensors required. Understand how force is transmitted through your body at foot strike and push-off. • Detailed Biomechanical Feedback Receive professional-grade feedback on: Posture & alignment Left–right symmetry Center of mass (CoM) stability Contact time and GRF angles Stride efficiency and propulsion • Scoring System & Insights Get personalized scores across four domains: Stability, Efficiency, Symmetry, and Mobility — all computed using evidence-based benchmarks. • Custom Exercise Recommendations Based on your biomechanics profile, the app suggests targeted drills to correct imbalances, improve propulsion, and boost running economy. • Progress Tracking Visualize improvements in joint angles, contact time, vertical oscillation, and more over time. ///How It Works/// Just set your phone on a stable surface and run. Our system captures and processes your movement using advanced pose tracking and physics-based modeling — including real-time GRF estimation. /// Who It’s For /// Runners who care about form, not just pace Coaches, therapists, and biomechanists Athletes aiming for injury-free performance gains Data-driven individuals seeking clarity in their training No Sensors. No Lab. Just Science.
