I love the Fitbit Charge. It does everything I need it to do with calorie counting, - I connect it to MyFitnessPal - with tracking exercise, and tracking my sleep. I’ve slept a lot better since working out my sleeping pattern with this device, and I like that you can change the interface on the tracker face. I never wear a watch so it’s great that this has the time, and I love that it gives you call notifications on the band. I also like the silent alarm feature if you don’t want to be woken by a loud song from your phone.
