reviewed several new pedometers a couple of months ago. The Fitbit is a paperclip-shaped gadget that tracks your footsteps and records your progress on personal website dashboard. It also uses Bluetooth to sync data directly from the device to your desktop computer.
In September, Fitbit announced plans to release an upgraded version that will use Bluetooth to also sync to a mobile phone. This review at Ars Technica says the sync-to-phone function will work with Apple's iOS but is not yet available for Android phones.
Fitbit is taking pre-orders for the new $99 Fitbit One. If you want the Fitbit Zip, which will track footsteps without the Bluetooth syncing, it's available now for about $60.
