The Under Armour Armour39 Module and Strap works with any athlete during any workout. After you snap it around your chest, pair this stand-alone system with your Bluetooth enabled iPhone or iPod touch to set up your profile and get started tracking your workout. The Armour39® module will store your biometric information and sync with the app on your iPhone or iPod touch. The strap stays dry and in place for increased accuracy.
The unique WILLpower™ measurement system of the Armour39® module is based on an algorithm that combines how long you work out, what you did, profile information like gender and weight, and key heart rate measures to give you a single score. It allows you to set a target every day and work toward achieving it.
