For Christmas last year I got a Fitbit as did my wife and daughter. Since they both had iPhones they were able sync to their phones and they made fun of me because my Lumia 928 couldn't. Knowing Cyan was being released, I told them just wait a couple of weeks and I'll be able to do it as well. Weeks came and went and I still couldn't sync my phone and Fitbit. Ended up losing my Fitbit and updating my 928 to an Icon. Just got a new Fitbit this Christmas and, guess what? I still can't sync my Fitbit to my phone.
I love my Windows phone, but this is the big problem. Unless Microsoft can close this app gap and update cycle, I'm afraid WP may be doomed.
Looking forward to my Denim update. Hopefully, I won't be saying the same thing next year at this time!
