Features
Read full description

FormX is a motion analysis app dedicated to perfecting your sports and training form. Its standout feature is the ability to play and compare two videos side-by-side simultaneously. It's the perfect tool for comparing your movements against a pro, or tracking how your form has evolved over time. Furthermore, FormX lets you measure movement durations and visualizes the exact time difference between two videos down to the split second. Whether it's a golf swing, baseball pitching and batting, or a track and field sprint start, this app supports performance improvement in any scenario where body movement, speed, and timing are critical! [Key Features] Dual Video Comparison (Side-by-Side Analysis) Play videos of your "past self" and "current self," or a "pro athlete" and "yourself" side-by-side simultaneously. Visually comparing them reveals subtle differences in form and timing that are hard to grasp through words or feeling alone. Precise Time Measurement & Gap Comparison Accurately measure the time of specific movements in your videos! Using the dual comparison mode, you can check the exact "time gap" between the two videos at a glance. By quantifying delays and speed differences, you can elevate the quality of your practice. Advanced Playback Controls Supports slow-motion and frame-by-frame playback. Review your form in deep detail without missing a single split-second movement. Export Analyzed Videos Save your side-by-side comparisons and time-stamped analysis videos directly to your camera roll! It's incredibly easy to share with your coach, friends, or upload to social media. AI Pose Detection (Body Pose Overlay) Automatically tracks joint and skeleton movements of the person in the video and overlays them on the screen. This is highly effective for checking body axis stability and core balance. Ad-Free Option (One-Time Purchase) Upgrade to completely remove in-app ads. Enjoy a wider, distraction-free screen so you can focus entirely on your analysis. [Highly Recommended For:] Athletes who want to compare their form side-by-side with pros or advanced players. Competitors in sports like track and field, swimming, and racing who want to improve their form and shave off split seconds. Players wanting to analyze pitching mechanics in baseball, or swing speed and timing in golf. Coaches and instructors looking to provide clear, visual feedback to students using side-by-side videos and hard data.
