I'm Luke Westaway for CNET here at Mobile World Congress in Barcelona.
We're taking a look at Sony's new Smartband.
Every company seemed in to making these wearable fitness trackers at the moment, and Sony is no different.
I like the design of this one.
It's very simple and it has this pleasant soft-touch, rubber feel to it.
Now, the Smartband actually comes in two bits.
There's the rubber wristband that goes around your wrist, and then, if
I pop this open, you can see it's got this little sensor box on the inside.
Now, Sony calls this the Core.
So, what can the Smartband do?
Well, it measures your steps and it talks to your phone, building up a lifelog, a whole database profile of your activity.
You examine that using Sony's Lifelog app, which looks pretty cool.
It has this interactive time slider which lets you journey back to check out when you were asleep, and it even knows when you were looking at certain apps.
So, you can check just how often you were looking at Twitter.
It can also deter thieves.
Once it's paired with your mobile, the wristband will vibrate if it gets too far away from your phone.
There's one more feature I want to talk about, and that's that if you tap the Smartband, it will create what Sony calls a Life bookmark.
Now, what that does is commands the device to make a little note of where you are, who you're with.
So, you can create a little snapshot of your social situation.
It's coming out in March.
It's gonna cost about â?¬99.
Would you wear one of these?
Let me know.
