PaceBoss app for iPhone and iPad

PaceBoss is the worlds first sophisticated audio biofeedback system. The system will advise you when to adjust your pace, and if you dont comply, the system will advise you more insistently. This will go on until the system feels that you simply wont comply, at which point PaceBoss will advise you thats it giving up and begins monitoring you at whatever pace your moving at that time - just like a human being. But, the best value with PaceBoss is the celebrity voices. What could be more motivating than to be guided through your exercise regimen by the very person who most inspires you in life?
