About this app

The developer's US App Store description, in full.

FencingVision is the AI-powered real-time fencing analysis app designed for fencers, coaches, and enthusiasts of foil, epee, and sabre. Using on-device machine learning and Apple Vision body pose detection, FencingVision turns your iPhone into a portable fencing laboratory - no sensors, no wearables, no setup. ## REAL-TIME BLADE TIP TRACKING Watch your blade tip traced live on screen with a glowing laser trail. Our proprietary BladeEstimator infers the grip position and tip direction from your wrist and elbow keypoints, then projects the full blade beam and tip marker in real time. The smoother your motion, the smoother the trail - perfect for studying attack angles, lunges, and ripostes. ## SIX VISUALIZATION MODES Switch between six focused display modes to isolate exactly what you want to study: - Tip Only: laser tip and trail - Tip + Fencer: tip with skeleton and box - Tip + Fencer + Blade: full visualization - Blade + Fencer: blade beam with skeleton - Fencer: skeleton and bounding box only - Blade: blade beam only ## MULTI-FENCER DETECTION FencingVision detects and tracks multiple fencers simultaneously on the piste. Each athlete gets an independent skeleton, blade estimate, and tip trail, color-coded for easy identification - ideal for analyzing bouts, lessons, and sparring sessions. ## WYSIWYG VIDEO RECORDING Record what you see. Every overlay element - blade, tip, trail, skeleton, box - is composited directly into the saved video at 720p H.264. Share clips with your coach, post to social media, or review frame-by-frame after training. Recordings save directly to your Photos library. ## POWER MODES Choose the right balance of performance and battery: - Performance: 30 FPS for the smoothest tracking - Balanced: 20 FPS, the recommended default - Power Saver: 12 FPS for long sessions and thermal management ## PRIVACY-FIRST, ON-DEVICE AI All inference runs on the Neural Engine or GPU inside your iPhone. No video leaves your device. No cloud uploads. No accounts. Your training footage stays yours. ## KEY FEATURES - Real-time blade tip and grip inference - Catmull-Rom spline tip trail with alpha decay - 6 visualization modes for focused analysis - Multi-fencer detection with per-athlete trails - WYSIWYG H.264 video recording at 720p - Adjustable blade length scale and fencing hand (auto/left/right) - Thermal-aware power management - 17-keypoint COCO skeleton overlay - Adjustable score thresholds and tracker settings - Save recordings directly to Photos ## WHO IT'S FOR - Competitive fencers refining technique - Coaches providing visual feedback - Clubs running group lessons - Parents recording young athletes - Martial arts enthusiasts studying blade sports ## REQUIREMENTS - iPhone with iOS 17 or later - A12 chip or newer recommended (for Neural Engine acceleration) - Camera permission for real-time detection - Photos permission for saving recordings Download FencingVision and transform every training session into a measurable, visual, shareable experience.
