Alongside the Z2 and Z2 tablet at MWC earlier this year, Sony also launched its own fitness tracker to work alongside a life-logging app. It tracks movement, exercise and sleep. Form factor is similar to the likes of the FitBit range of devices, but the Sony Android app has a lot of other tricks up its sleeve. 

To some, the life-logging app might sound awesome. To others, plain creepy. It tracks all your social updates, events and everything in between to keep a digital journal for you automatically. Combined with your fitness data, it gives an in-depth look at the way you live your life, both in real-world and online-presence. 

Is the smartband enough to take on the Fitbits of this world?
