The Nike+ FuelBand SE ($99-$150) includes a few extra features from the previous FuelBand. Like the older model, the FuelBand SE tracks calories, steps, and Nike Fuel points, but the new model now also tracks sleep. It also aims to improve calorie burn and Fuel point accuracy with a new feature that allows you to log different types of workout sessions (such as yoga or weight lifting). The water-resistant FuelBand SE syncs automatically with the iPhone app, so you don't have to push a button to upload data as you do with the older model. Neither the FuelBand SE nor FuelBand is compatible with Android devices.
