Tennis Radar: Ball Speed Gun

Discover how fast you really hit! Tennis Radar turns your smartphone into a highly precise speed-tracking tool. Forget expensive radar guns—all you need is a video of your serve, forehand, or backhand to instantly calculate your ball speed in km/h or mph.

Built for tennis players, coaches, and enthusiasts, this app relies on hard math and physics, not guesswork or unpredictable AI. By using the standard length of a tennis racket as a physical scale, Tennis Radar analyzes the exact distance the ball travels between individual video frames to give you an incredibly accurate velocity reading.

HOW IT WORKS (IN 4 EASY STEPS):

1. Import & Trim: Import a video from your gallery or record a new one. Use our precision trimming tool to isolate the exact moment of your swing.
2. Find the Impact: Use the frame-by-frame navigation controls to find the exact millisecond the ball leaves your racket.
3. Calibrate: Pinch and zoom into the video for pixel-perfect accuracy. Place a dot on the top of your racket, the bottom of your racket, and the ball.
4. Track & Calculate: Advance the video by 1 to 3 frames, tap the ball's new position, and instantly get your shot speed in km/h!

POWERFUL FEATURES: • Precision Frame-by-Frame Player: Step forward and backward frame-by-frame to find the absolute perfect point of impact. • Advanced Trimming Tool: Easily isolate your swing. Use the "Zoom Range" feature to expand small sections of a long video for effortless micro-trimming. • Slow-Motion Support: Fully compatible with high-framerate and slow-motion videos. The app automatically detects slow-mo metadata, or you can manually set the speed multiplier (1x, 1/2x, 1/4x, 1/8x, 1/16x) to ensure the math is always flawless. • Pinch-to-Zoom & Pan: Zoom deep into the video while placing your tracking dots to ensure maximum accuracy without the dots getting in the way. • 100% Offline & Private: No AI, no cloud uploads, and no internet required. All video processing and speed math is done locally on your device.

TIPS FOR THE BEST RESULTS: • Perpendicular Angle: For the most accurate physics calculation, film exactly from the side of the court, perpendicular to the ball's trajectory. • High Framerate: Record your videos in 60fps or 120fps. More frames mean less motion blur and highly accurate tracking! • Clear View: Ensure the entire tennis racket and the ball are clearly visible during the swing.
