So far I have expanded my competitor comparison to two new products. Here are all my competitors:
1) Nike + iPod running assistant helps you keep track of your exercise and compare it with other people
2) FitBit - extremely similar to above, but you don't need an ipod. Its streamlined but more expensive
3) Polar GPS watches. These watches keep track of your distance through GPS. They are extremely popular for runners and cyclists because of how accurate they are.
4) Telemonitoring. This was my original competition. Because I feel my product is still involved with healthcare its important that I keep this product as part of my competition, although I feel it is the least relevant compared to the others.
