→ traqqer's AI pinpoints your weaknesses and shows how to fix them
Is your form really right?

What I realized after becoming a coach is that "there are countless athletes who could improve so much more with proper coaching."
traqqer was born to provide that "extra push" to help athletes reach their potential.
Is your form really right?
→ AI checks every movement so your weak points are obvious at a glance
Just upload a practice video and AI analyzes your form using expert track & field knowledge. It compares your movement against an ideal model and points out exactly what to improve. Stop relying on feel and turn every session into a step toward your next personal best.
Confident in your form?
→ AI analyzes it in 3D and reveals habits you can't see
Just upload a video from your phone. AI analyzes it from every angle to build a 3D skeleton model, quantifying body sway, joint angles, and velocity. Discover the weaknesses you'd never spot on your own — objectively, with data.
Unsure what to train? Ask your AI coach
→ A workout built just for you, with zero wasted training
"I want to push hard today" or "I need a light session" — just tell it your goal and intensity, and AI builds the optimal menu based on your past data. No more monotony, always effective training.
