FormCheck AI — AI-powered video form analysis
Just upload or record a video, and AI analyzes your form instantly.
Golf, weight training, baseball, ballet — whatever you practice, FormCheck AI answers "why isn't it working?" with clear, logical feedback based on your own video.
ABOUT THE APP
FormCheck AI automatically analyzes your sports form and training movements from a video taken on your phone.
No special equipment or expert knowledge required.
AI breaks your movement down frame by frame and evaluates posture, angles and balance objectively — turning the "quality of movement" you could only feel into something you can actually see.
KEY FEATURES
High-precision AI form analysis
Upload a video of up to 10 seconds and AI automatically extracts the key frames.
Each frame clearly shows what's good and what to improve — swing path for golf, joint angles for weight training, posture axis for dance. Habits you never noticed become obvious at a glance.
Skeleton overlay
AI detects your body's joints and draws your skeleton right on the video and on every analyzed frame, so you can visually check your posture axis and joint angles.
Frame-by-frame feedback
AI automatically picks the key moments from your video and reviews your form one frame at a time, with concrete comments.
For example: "Open your chest and lean slightly forward to engage your back muscles", "Your arm opens too early at release", "Your weight drifts right at the start of the swing".
You'll know exactly which moment to fix and how — understanding your form visually and logically, not by feel.
Training suggestions for improvement
Based on the analysis, the app automatically suggests training to improve your movement — "focus on contracting your lats", "stabilize your core", "strengthen your postural muscles" — concrete, theory-based advice, instantly.
A timeline that shows your progress
Every analysis is saved automatically and displayed as a timeline.
Look back on how your form has changed and see your own growth. It also works great as a training log.
