I’ve had this Fitbit Charge HR for about 4 weeks and I’ve had my Polar FT4 for about 2 years now.
Fitbit is great if want to know how many hours I sleep, my daily calorie burn, and my steps. However, I don’t really need to know those things but it is cool to know. The cons are that I hate wearing it on my arm all the time and it doesn’t work effectively for me when working out. As you can see above, the heart rate on the fitbit is usually off.
The Polar FT4 is great because I only use it when working out. It’s purpose for me is to only count the number of calories that I burn when active. The band that goes around your waist isn’t horrible but you should wash it every so often.
The Polar FT4 is the winner!
