Swing! Tennis Simulator

[Tennis Swing Checker - Master Your Forehand]

Analyze your tennis swing instantly using your iPhone's motion sensors! This app provides real-time feedback on your racket face angle and swing trajectory to help you achieve the perfect forehand.

[Key Features]

・Real-Time Swing Analysis: Automatically detects the "Impact" point at 3.5G acceleration. It instantly categorizes your shots, such as Spin, Flat, or Slice.

・Detailed Metrics: Displays the precise racket face tilt (Open/Closed) and swing angle in degrees at the moment of impact.

・Visual Trajectory: Recreates the ball's flight path on your screen based on actual swing data, giving you a clear image of your shot on the court.

・Haptic Feedback: A powerful vibration triggers the exact moment impact is detected. You can use this vibration as a guide to calibrate your swing speed.

・Privacy First & Ad-Free: As a paid app, there are no advertisements. We do not collect any personal data, so you can focus on your training with peace of mind.

[Important Notes - Please Read]

・Right-Handed Only: Currently, the analysis logic is optimized exclusively for right-handed players.

・How to Use: Hold your device in landscape orientation (with the volume buttons facing the ground) and swing with the screen facing the direction of your shot.
