HeartCalc overcomes the problem that most exercise programs have in that they express the intensity of exercise as a percentage of maximum heart rate, while most heart-rate monitors must be programmed as an absolute number of heart beats per second, based on the user's resting and maximum heart rates.
Heart Calc uses the Karvonen method of calculation, based on an effective heart-rate "range" (from resting to maximum heart rate).
Simply enter your maximum and resting heart rates, then the percentage limits of the exercise band you wish to train in. A simple Click of the Calculate button will produce the limits to which you should set your heart-rate monitor.
Requires a Mac (68k or PPC) with MacOS 7.5 or greater.
