The Answer!
While on the treadmill, I accessed the iTunes store from my iPhone and purchased this app. Then I wrapped my hands, set the timer, put my gloves on and worked 12 rounds on the heavy bag, without having to look at the clock or think about anything but my rounds. Sound is nice and clear, setup is intuitive – and I dont need to carry a big timer to the gym anymore. Thanks Chris!!!
