Sony on Thursday unveiled its SmartBand 2 fitness tracker. It has an advanced heart rate sensor and a variety of communications capabilities. It informs wearers when they get calls, messages, emails or notifications on social media sites. It sports interchangeable silicone rubber bands in black, white, pink and indigo. The SmartBand 2 is compatible with any device running Android 4.4 KitKat or later, as well as iOS 8.2 or later. It can be submerged in up to three meters — nearly 10 feet — of water without damage.
it seems good,but it's a little expensive for me ,so i bought a cheap TW64 from tinydeal,which can monitor sleep and heart rate too.
