Currently I own a Fitbit Zip and Flex which I alternate in use on a regularly basis. It's been a great and affordable device to help track my steps, distance, diet, water intake. The Fitbit app also allows you to "add-in" other activities to your work out which is a benefit to your total workout log. I also have a. Polar Watch which monitors my HB which I used off and on, but not as regular use as my Fitbit. I am just wondering how many folks will be interested in purchasing the apple watch for their fitness needs? If the price might be too steep for them? I also am interested to see how Fitbit and other fitness/vital trackers will do with Apple watches/competitors? I don't think I'll stop using my Fitbit/app, since it is tied into my optimal health at work health insurance, but am interested to see what will be next.
