I finally decided to get the Polar A300 after my FT4 crapped out. It was a toss up between Polar and the Garmin Vivofit2. So now there are apps that go with it so I can see my wkouts, sleep etc on-line after setting up an account. My question is, what apps do you use? Any favorites? I don't have my polar yet but I downloaded the polar flow app. Do I need the polar beat app too? It's confusing! I like having the info but don't need to be overwhelmed with repetativeness. Any suggestions would be appreciated.
