Pose & Tracking vs Dirty Knife Timer

'Pose & Tracking' is an app that can visualize posture and the trajectories of specified body parts from a video. It not only visualizes overall posture but also allows you to track the movement of hands, feet, head, and the body's center of gravity, capturing motion details more precisely. By visualizing posture and body part trajectories, this app can help improve sports performance and rehabilitation exercises. Whether it's basketball, darts, golf, athletics, strength training, baseball, soccer, Mölkky, or other activities, it allows for simple visualization of posture and movement, making it useful for motion analysis and form improvement. It is helpful not only for athletes themselves but also for coaches, managers, and instructors who guide movement and technique. Beyond sports, it can also assist in rehabilitation, such as observing gait and supporting movement assessment. Additionally, this app does not require cumbersome membership registration or login, allowing you to start visualizing posture immediately after installation. There is no limit to the number of video analyses, so it can be used repeatedly as needed.

This application is used to train quick-draw knife techniques, recording draw speed as a timer to enhance self-defense ability. We utilize the iPhone’s accelerometer to achieve this. Instructions: 1. Set your phone’s volume to maximum. 2. Set the countdown timer (can be a fixed time or random). 3. During the countdown, do not turn off the screen. Place the phone in your pocket. 4. When you hear the beep, immediately draw your knife. 5. The moment you come to a complete stop after drawing, the app will use accelerometer data to determine that you have finished the draw, thus calculating the time it took to draw the knife.
