"Motion Snapshot" is an app that automatically extracts people from videos to create motion trail videos that visualize their path. By extracting only the person from the background and overlaying their movement trails, it is perfect for analyzing sports form, checking dance choreography, and improving rehabilitation movements. Also, with "Whole Area" analysis, you can track the trails of non-human objects like basketballs, soccer balls, baseballs, golf clubs, and darts. * We strongly recommend using videos shot with a fixed camera. Key Features: - Motion Trail: Visually represents movement trails, enabling analysis of form and motion. - Easy to Use: Automatically generates motion videos just by selecting a video. - Customization: Freely adjust frame interval, opacity, and display patterns. - Unlimited: No registration required, with no usage limits—analyze videos as many times as you want. Recommended for sports coaches, dancers, physical therapists, and anyone interested in motion analysis.

Verdict
The clearest difference is in-app purchases: J at none against Motion Snapshot's 1. J also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 5 weeks). On price, device support and iOS requirement there is nothing between them.
