I been using my I-phone and once in a while I use my Garmin 310 sport watch....I prefer the I-phone as it up loads to the cloud by self but does lack the HR part. I saw this new watch here on the site and thought it looked cool and functional...So what are you using and why? And, will strava or what ever site you use play a roll in what device you will buy next.
