If you can recall, the Smartband is similar to the Fitbit, and other fitness trackers, in that it is a simple rubber band with sensors that can count number of steps. It also comes with vibration and LED notification, to alert you to notifications from your paired phone. It will also read your motions while you sleep in order to wake you up at the right point in your sleep cycle. Sony also says the Smartband acts as a sort of digital leash for your phone, vibrating if you get too far away from your device.
As in true Sony fashion, the device is waterproof, with an IP55/58 rating, so you can wear it in the shower or take it for a run in the rain.
Pairing is done via NFC and connects using Bluetooth. If you don't have an NFC phone (who doesn't?), you can still pair via normal Bluetooth methods.
One disadvantage to the Smartband is it is not nearly as fully featured as something like the Galaxy Gear Fit. It doesn't even try to match the Fitbit Force, which now has a small screen to give you time and number of steps. This puts Sony squarely in competition with the Fitbit Flex, and the price for the two devices are comparable. However it would have been good to see Sony try and compete with some of the more feature-rich solutions out there. We will have to see if the removability will add enough functionality to make it a compelling option.
Lifelog App. I have been playing around with the app for a while now, but definitely feel that it is lacking without a wearable like the Smartband to feed into it.
If you are interested, you can pick up the Smartband for $99.99 now at Brick and Mortar Sony Stores and online, in addition to other retailers like Rogers. As a bonus, if you purchase a new Android 4.4 phone on select Share Everything plans, Rogers will throw in a Smartband for $24.99.
If you are unsure, you can wait for our review of the device. With the device review, we will also look at the Lifelog app, which frankly is nothing right now without this wearable.
