Move Smarter. Improve Your Form. ACL injuries can be devastating — especially for athletes who jump, pivot, and land as a part of their sport. But what if you could get an early look at how you move and where the injury risk might be hiding? Hurtblocker gives you a simple, at-home movement check-up. No fancy gear. No complicated setup. Just clear, fast feedback on your landing mechanics and performance. Whether you’re an athlete, a coach, or a parent, Hurtblocker helps you identify movement patterns that may be linked to a higher chance of ACL injury — particularly poor landing form, asymmetry, or instability. What the App Does: • Guides you through specific athletic stress tests • Uses your phone or tablet camera to capture your movement • Analyzes key joint positions during landing • Flags movement patterns associated with elevated ACL injury risk • Provides a simple summary of your results • Offers curated links to expert resources, training programs, and clinics Who It’s For: • Athletes in high-impact sports (e.g., soccer, football, basketball, volleyball, etc…) • Coaches and trainers who want a quick screening tool for their teams. • Parents of young athletes looking to keep them safer. • Rehabilitation professionals needing a first-line assessment. • Anyone curious about how they move and where to improve. Why It Matters: • Most ACL injuries happen during non-contact events — landing awkwardly, cutting without control, or decelerating improperly. These moments often reveal weaknesses in neuromuscular control that can be trained — but only if you know what to look for. • This app isn’t a diagnosis or a replacement for medical advice — it’s a movement awareness tool designed to highlight patterns that may need further attention. Learn & Act: After your assessment, the app connects you to: • Research-backed neuromuscular training programs. • Articles and videos to improve movement control. • Local or virtual clinics and professionals for further support. Quick. Easy. Insightful. • All you need is space to jump, a smartphone, and a few minutes. You’ll get feedback that helps you take the next step — whether that’s better training, safer habits, or further conversation with your coach or clinician. Disclaimer: This app is not intended to diagnose injuries or provide medical treatment. It is a performance screening tool to help identify movement trends and provide educational resources. Always consult a healthcare provider before starting a new training or rehab program.
