AI Fitness Form Checker
An AI-powered app that uses your phone camera to analyze exercise form in real time, giving instant corrective feedback like a personal trainer would.
Moat
The Prompt
Build a mobile web app that uses the phone camera to detect body pose in real time using MediaPipe Pose. Analyze joint angles for 5 exercises (squat, deadlift, push-up, lunge, plank) and give visual and audio feedback on form. Include an exercise selector, real-time skeleton overlay on camera feed, audio cues for corrections, rep counting, and a session summary with form scores. Use React with TensorFlow.js or MediaPipe for pose detection.
What You Can Build
- ✓Real-time pose detection via camera
- ✓Form analysis for 5-10 core exercises
- ✓Visual overlay showing joint angles and alignment
- ✓Audio feedback cues for corrections
- ✓Rep counter
- ✓Session history
What's Hard
- ✗Pose estimation accuracy varies with lighting, clothing, and camera angle. Complex movements like Olympic lifts may need multiple camera angles. Mobile processing power limits real-time analysis quality.
What You Lose
- −Test form detection accuracy across body types
- −Verify audio feedback timing feels natural
- −Ensure camera overlay renders smoothly at 30fps
- −Test in various lighting conditions
