The Fitbit One is the updated version of the previously reviewed Fitbit Ultra.
Unlike the Ultra, which could only be ordered from the US, the One is available in Australia, although at a steeper price than in the US ($US100).
At first sight, the One contains many of the features found in the Ultra, including readings for calories burned and stairs climbed, as well as the sleep tracker.
The most noticeable visible change is the One’s smaller size. It also comes with a more secure clip for carrying on your person and an equally secure pouch for when you're sleeping. The new silent alarm function means you can set it so the One only vibrates to wake you.
While the Ultra came with a charging/wireless sync station, the One comes with a charging cable and a very small USB dongle that you can plug into any PC, install the software and have it sync without the need for a charging station. The upside is that it’s small, but the downside is you now occupy two USB places if you want to charge and sync simultaneously.
Another upside to the One is it now syncs via Bluetooth, without a wireless dongle, with a variety of devices including the iPad 3, the iPhone 4S and 5, and Samsung Galaxy S3 and 4 models, with more to come.
Using the same Fitbit dashboard as the Ultra, the One only requires new software to be installed. It promises to be able to sync with a number of apps on the market such as RunKeeper, MyFitnessPal and Endomondo – we only tried it with MyFitnessPal because of the better Australian food diary database of that app, and found that it works.
Fitbit is also planning to release a wristband called Flex, which seems to be promising similar things to the One (without stairs tracking) and its competitors Jawbone UP and Nike FuelBand.
The One is a good next step in the development of these fitness trackers, although we expect a few more iterations until they are perfected. They still have lots of room for improvement and extension to the point where they become as inseparable from their owners as smartphones are.
