Armour39® is the first-of-its-kind performance monitor that tracks heart rate, calories, real-time intensity, and WILLpower™—the first true measure of an athlete that boils your workout down to a single score 1.0-10.0. And, unlike other heart rate monitors that only average your heart rate data, Armour39® precisely captures every heartbeat no matter your workout—from endurance running to interval training. So now, you won’t just see yourself getting better...you’ll be keeping score.


  • Stores your biometric info—including heart rate, calories burned, real-time intensity, and WILLpower™—and transmits it automatically in real time to the Armour39® App or Watch
  • Compatible only with iPhone® 4s, iPhone® 5, iPhone® 5c, iPhone® 5s, and iPod Touch® (5th generation)
  • Highly responsive and designed to keep contact with the body so you get precise measurements no matter what you wear it to do
  • Using a Bluetooth connection, the Armour39® Module wirelessly transmits workout data in real-time when you're within range of your iPhone or iPod touch; go out of range and it stores your workout data, automatically transmitting your info to your app when you're back in range
  • Transmits within 15 feet of your display device (see above for compatible devices)
  • Module is sweat proof (cannot be submerged in water)
  • Long lasting coin cell battery is ready to go when you are
  • Not just a strap…it actually performs; it wicks sweat and stays put thanks to grippy Nano technology that keeps you comfortable and focused
  • Sensing pads detect the body’s biometric info and deliver it to the Module
  • Comfortably fits a ribcage measuring 27”-52” around (see models for fit)
  • Strap is sweat proof (cannot be submerged in water)
  • To clean, remove the Armour39® Module and hand wash
