Im so glad I found this app. I stopped wearing my Fitbit when I got the Apple Watch but I hate working out in my watch (its not the sport one) so I pulled out my Fitbit but I wanted the information to sync with my Apple Health App and this is the app for that. I was a little skeptical but I followed the reviews and the app works great. During my workout I will turn off the health tracker for my iPhone and turn it back on during the time Im wearing my Apple Watch. So far no complaints...
