One of the most basic fitness tracking devices is the $150 Nike+ FuelBand.
The black rubberized band keeps track of your steps and miles log, then syncs the data through Bluetooth to an iOS app.
Sorry, it's not Android compatible just yet.
The downsides are that you can't input any more info such as calories consumed or other activities like weight lifting.
The Fitbit line of products offer several features at reasonable price points, anywhere from
$60 to $100.
The slim, easy-to-wear device is handy for recording steps, mileage, and stairs climbed.
It will sync automatically with your online account, and even allows for some friendly competition amongst other Fitbit users.
Finally, the BodyMedia fit offers a wide array of features, but at a cost and convenience.
People love this sleep-tracking feature amongst the other basic measurements, but complain about the $120 to $150 bulky armband and the monthly subscription fees.
