The Fitbit Zip is an entry-level model that is quite small, and it can track steps take, an estimated distance traveled, calories burned, and you can scroll through all of this features. It has a USB dongle and can auto-sync with one’s computer in range for up to 20 feet. It works with low-power Bluetooth 4.0 devices, and it is water-resistant.
Then there is the Fitbit One (pictured here), which is smaller and sleeker than last year’s model. The Fitbit One has a built-in altimeter, so it can keep track of elevation gains, more accruate results for calories that you burn. It can be worn at night on a wristband, and it will track your sleeping as well.
You like these? If you want the Zip, it costs about $60 in five colors. You can pre-order the One for $100, but it won’t get to you until October.
