Step 1
Kenny Demo App
Motion Lab
Upload a pre-recorded instructor video and the app measures head, arm, torso, and leg coordination plus speed of movement. Then upload a student attempt: the student plays back in slow motion with a colour stickman ghost of the instructor overlaid on their body, timed coaching notes follow the video, and you can step forward or backward frame by frame.

Step 2
Student attempt
Everything runs locally in the browser. Videos never leave this device — only pose figures are kept, and the instructor reference is remembered for the next visit.
Instructor profile
Coordination & speed
Upload an instructor video to see how the head, arms, torso, and legs share the movement and when each body region reaches peak speed.
