From movement to feedback
Know what to work on, while you move.
Apple Vision estimates joint positions on your device, and FormLab analyzes the movement. Automated form analysis currently supports squats, with different checks for front and side views.
01Front view
Knee alignment
Check for knees caving inward and left-to-right asymmetry.
Example feedback: Practice slow reps while keeping each knee tracking over your toes.
02Side view
Squat depth
Follow your depth and rep count, with form feedback for each repetition.
Example feedback: Insufficient depth — check your depth on the next rep.
03Side view
Forward lean
See when excessive forward lean or heel lift changes your form.
Example feedback: Keep your whole foot on the floor as you review the movement.
