FanEye: Court Sports Replay

Settle the last point with replay. FanEye supports single- and multi-camera challenges, slow motion, and frame-by-frame review for disputed calls.

FanEye is a challenge replay system designed for badminton training and casual matches.

When a landing call is disputed, FanEye helps you lock the latest moment, review it in slow motion, step frame by frame, and save a short reference clip.

FanEye is not an automatic referee and does not replace official tournament line-call systems. It does not automatically detect the shuttle landing point or call IN / OUT. Its goal is simple: help players review close calls faster and keep the game friendly.

Key features:

• Single-camera challenge: review key moments with one iPhone • Multi-camera challenge: sync challenges across multiple phones • Slow-motion replay: play, pause, step forward, and step backward • Frame-by-frame review: inspect the landing moment more carefully • Save Clip: save an approximately 3-second reference clip around the current point to Photos • Local processing: video is cached temporarily on the device by default

Best for badminton training, casual matches, amateur games, and disputed on-court calls.

FanEye V1 does not automatically judge IN / OUT. Replay results should be confirmed by the players on site. Multi-camera mode syncs control commands only and does not upload video.
