In the world of the iPhone, apps—applications that give users news, provide them with tools like GPS systems and maps, or help them engage in activities like downloading music and recipes or playing games—are key. A new iPhone app is dedicated to muscles, trigger points and referral patterns.

The app was launched by Real Bodywork; it features 70 muscles, and 100 trigger points and referral locations.
