## What is AI Pitch Speed?

AI SpeedGun measures baseball pitch speed using your iPhone camera and artificial intelligence. No radar gun needed — just record from behind the pitcher and the AI finds the ball and calculates its speed.

■ Key Features
• AI pitch speed: Record from behind the pitcher; the AI (YOLOX) detects the ball, calculates the average speed and announces it by voice.
• Auto mode: Detects the pitching motion and measures automatically, including continuous measuring.
• Pre-check: Checks in advance whether the ball is detected well in your environment.
• RPM analysis: Guides you to calculate ball spin from the captured photos.
• Analysis: Step through the saved photos and video frame by frame, check the ball's path, and save or share it as a video.
• Recording mode: Record pitching videos and analyze saved videos later.
• Records: View your measured speeds in a chart and list by date.
• Community: Find and post catch-ball meetups, catch-ball hotspots, lessons and ballparks on a map around your area of interest.
• Rankings: Compare pitch speeds with other users in your area.

■ Tips for accurate measurement
• Record within 1 meter behind the pitcher.
• Enter the pitcher-to-catcher distance in Settings.
• Keep the sun behind you and avoid white objects in the frame.
• Use a clean white baseball.

■ In-App Purchases
• Remove Ads: Remove all ads with a one-time purchase.
• Support the Developer: Optional tips if the app helps you (no features unlocked).

Results may vary with lighting, distance and angle, and the app does not replace official measuring equipment.
