Fitbit has launched two new smart fitness gadgets, the Fitbit One and the Fitbit Zip. They're designed to track your activity throughout the day to find out quite how sloth-like you really are.
The higher-end of the new pair is the Fitbit One, the successor to the Ultra tracker we checked out earlier this year. It updates the design, making it a lot slimmer by using a separate clip rather than an inbuilt one. It works in much the same way, though. It features a pedometer, an accelerometer and an altimeter in its little body, letting it work out not only when you're taking a step but also whether you're going up stairs or just coasting along the pavement.
It monitors your activity throughout the day, and can even be used as a sleep tracker. The Fitbit One includes a vibrate function that can be used as an alarm clock, intended to wake you up when your body's ready rather than at 6:30am on the dot - or whenever your schedule may demand.
The main functional upgrade over the original Fitbit Ultra, though, is that the Fitbit One features Bluetooth 4.0 support, which lets it sync with a compatible smartphone such as the Samsung Galaxy S3 or iPhone 5, on-the-go. With the Fitbit Ultra, you had to hook the device up to a little dock connected to a computer - you only got on-the-go updates from the device's own display.
The Fitbit One will cost £79.99 and is set to go on sale on 22 October.
If that sounds a little pricey to you, the Fitbit Zip may do the trick. This is the cheaper, friendlier new addition to the Fitbit family, and it sells for just £49.99. It's a little pebble of plastic that's powered by a watch-style disc battery rather than the rechargeable lithium type found in the Fitbit One, although Fitbit says it'll last for 4-6 months off a single battery.
You do lose some of the features, though. There's no altimeter in the Fitbit Zip, so it can tell when you're taking a step, but not whether you're climbing Everest at the same time. It does support Bluetooth sync, letting the Zip fire updates over to a phone during the day.
Both the Fitbit Zip and One use the same software as the Ultra, which lets you track your activity and progress with graphs and charts either on a computer or smartphone. The tracker twins have also been fully weatherproofed, and should even be able to survive a tumble in the washer.
The Fitbit Zip will be available from 1 October, and the One will go on sale in a few weeks on 22 October.
