FormLesson — Compare your moves side-by-side with the pros!

"FormLesson" is a dedicated mobile application designed to dramatically improve the efficiency of your dance and sports practice. By playing and comparing a professional's moves (reference video) and your own moves (camera preview or recorded video) simultaneously on one screen, you can intuitively identify your habits and areas for improvement.

【Main Features】

Perfect Sync Playback & Advanced Analysis: Play, pause, and seek with the reference and your video in perfect synchronization. ・Slow Motion: Change playback speed from 0.25x to 2.0x to catch every detail of fast moves. ・Mirror Mode: Flip the reference video horizontally to practice as if you are looking in a mirror. ・Video Conversion: Automatically convert unplayable video files into a compatible format within the app. ・Self-Timer Recording: Record your practice at your own pace with a delayed start timer.

2. Flexible Display Layouts: Instantly switch between three display modes to suit your practice environment. ・Split Mode: Splits the screen horizontally or vertically to compare the overall difference in form. ・Overlay Mode: Overlays your video onto the reference video with transparency (ghosting). Extremely effective for comparing angles and timing. ・PiP (Picture-in-Picture) Mode: Displays your video in a small sub-window while the reference video plays in full screen.

3. Audio Support & Detailed Editing: Powerful support for practice using audio files as well as videos. ・Audio Comparison: Supports audio playback and comparison. Perfect for checking moves synchronized with music. ・Metadata Editing: Edit and save song titles, artist names, and artwork (images) directly within the app.

Stress-Free Operation & Sharing: Features an intuitive control panel and collaboration tools. ・Quick Controls: Start/stop recording, swap media positions, and change playback speed with a single tap. ・Direct Sharing: Share recorded videos or edited audio files directly to SNS or messaging apps from the player screen.

5. User-Centric Customization ・Persistent Settings: The app remembers your last used playback speed, loop settings, display mode, and camera orientation for a quick restart.
