Previously the Fitbit range consisted of only one device - the Fitbit Ultra. This has been replaced however by a 2 model lineup consisting of the entry level Zip and the fully featured One.
The Zip contains the same core functionality as previous Fitbit devices - tracking steps taken, calories burned and distance travelled - but does not include stairs climbed or sleep tracking. The tracker syncs via an included USB dongle to your PC or via Bluetooth 4.0 to iPhones / iPads or Android devices supporting the technology. Power comes from a replaceable battery that provides 4 to 6 months of use.
The One does record stairs climbed as well as offering sleep tracking, but also adds a vibrate alarm function over it's predecessor as well as also offering the new Bluetooth sync functionality. The Fitbit One is rechargeable with a 5-7 day battery life.
The Zip will retail at £49.99 and the One will retail for £79.99, with the Zip shipping shortly and the One to follow close behind.
A slightly revamped website has been released to coincide with the new device launches... I actually think the web experience (and the way it ties into third party apps) is one of the key strengths of Fitbit.
I have long had high hopes for Bluetooth 4.0 low power technology so I hope this is the first of many personal network enabled devices to hit the market!
