Javelin Video Analysis app

Take your throwing performance to the next level with a powerful Javelin Video Analysis app built specifically for iPhone and iPad. Using advanced motion analysis, the app breaks every throw into five critical phases—Approach Run, Cross-Step, Power Position, Release, and Follow-Through—giving you a complete, frame-by-frame understanding of your technique. Instantly identify how effectively you build speed, create torque, and transfer energy through the throw. With visual markers highlighting key moments—green for maximum separation, blue for optimal bracing, and red for peak release—you’ll never miss the details that matter most.

Go beyond basic video playback with detailed, technique-specific metrics that turn your performance into measurable data. The app calculates hip-shoulder separation angles, bracing leg extension, elbow height, arm extension, and balance—all tailored specifically to javelin mechanics. Each phase is scored out of 10, with personalized feedback and actionable recommendations designed to improve your throw immediately. Whether you’re refining your release angle or optimizing your power position, every insight is built to help you throw farther, safer, and more efficiently.

Bring your coaching to life with professional-grade drawing and annotation tools. Use freehand sketches, lines, arrows, circles, and automatic angle measurements to visually break down technique and highlight areas for improvement. Customize colors and line thickness, track movement paths, and create clear visual comparisons between throws. Combined with precise frame-by-frame controls and ultra slow-motion playback down to 0.1x speed, you can analyze every millisecond of motion and capture the exact mechanics behind elite performance.

Designed for athletes, coaches, and researchers alike, the app also features manual metric tracking, athlete height and distance calibration, video library management, and seamless sharing options. Validate real javelin throws with intelligent detection, collect biomechanical data with pinpoint accuracy, and explore built-in “Learn & Train” resources covering technique, drills, and sports science. With support for both metric and imperial units and left- or right-handed athletes, this all-in-one platform delivers professional-level javelin analysis right in your pocket.
