This app is amazing!!! I love how you can easily sync it and change things with the watch on this app. It is very easy to use, which I love. There are no problems with this app. Some people have said that it takes to long to sync if your hours off. But that again anything that changes time including people take awhile to get us to it. But that doesnt even take long.
I like how there are different challenges with friends on this app that you could have. Like who can walk the most today, or burn the most calories. I also like how you can challenge yourself better. It shows the difference in steps between days/weeks/months/years.It is also very easy to setup. If you have a Fitbit, but need to get it ready you than need this app.
