Clay uses AI to measure your tennis serve speed directly from video. Record a serve, upload it, and the app analyzes the ball’s trajectory to calculate your speed and count your serves.
With the new AI Coach, Clay now goes beyond speed: it evaluates your technique, detects key positions like trophy pose and contact, and gives clear, actionable feedback to help you improve faster.
Your analyzed videos are saved in a clean, easy-to-browse feed so you can compare sessions and follow your progress. The app highlights your fastest serve, displays technique insights, and keeps everything securely on your device.
Training becomes more engaging with interactive quizzes and short lessons that teach proper mechanics and help you build a more consistent, powerful serve over time.
A short recording guide explains how to place your phone for accurate results. All processing runs locally on your iPhone, keeping every video private.
