Serve Speed Pickleball

How fast is your serve? Find out in seconds with just your phone. No extra gear, no subscriptions, no cloud services.

Serve Speed Pickleball turns your phone into a serve speed radar. Record a serve, and the app measures the ball speed right on your device - no cloud uploads, no subscriptions, no extra hardware. Your videos never leave your phone.

HOW IT WORKS

1. Position yourself behind the baseline, on the same side as the server
2. Hold your phone in landscape and frame the full court
3. Tap record a second or two before the serve
4. Stop after the ball lands

The app automatically detects the court, tracks the ball frame by frame, and estimates the serve speed using computer vision and 3D geometry. Results typically appear in under 30 seconds.

WHAT YOU GET

• Serve speed in mph with a confidence range
• Ball trajectory overlay on the actual court
• Court detection quality score
• Time-to-net and net clearance estimates
• Detailed timing breakdown of each processing phase
• Full serve history with thumbnails

SHARE YOUR RESULTS

Create a shareable slow-motion video with speed overlay, ball trajectory, and background music. Show off your fastest serve on social media or send it to your doubles partner.

ACCURACY AND TIPS

Higher frame rates produce more accurate results. 240fps is ideal, 120fps works well, and 60fps gives a reasonable estimate. Most modern phones support at least 120fps.

For best results:

• Keep the phone steady (use a tripod or rest it on a fence)
• Make sure both baselines, both sidelines, and the net are visible
• Avoid zooming in -- the app needs to see the full court
• Record in good lighting conditions

The reported speed is the estimated ball speed off the paddle at the moment of contact.

PRIVACY FIRST

All processing happens entirely on your device. No video is uploaded, no account is required, and no data is collected. See our full privacy policy at yolostart.com/privacy.

BUILT-IN DEMO

A sample serve is included so you can explore the results, try reprocessing, and create a share video before recording your own. The app also supports importing an existing video for processing if it was recorded following the same guidelines as recording within this app.
