As a wrestler, many of teammates had been hit with concussion. It was sad to see them in the sidelines for weeks as if they have been demoted to cheerleader. Understanding that young football players have as much concussions as wrestlers, I could sympathize with them. 'Spear-ramming' or tackling head-on was the number one contributor to football concussions. Our app intends to teaches young football players how to avoid this by gaming in the habit. Or else, it will impact their whole future. This was done in one day for a Major League Hacking hackathon. Also, credit to Raymond Ma for graphics.
