Turn your iPhone into a tennis racket. Instantly digitize your swing metrics, face angle, and trajectory! Ad-free & offline — practice smarter. [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.
