Misfit already set the bar high for activity tracker design with its Shine, now it's taking that further for the Shine 2.

The Shine 2 tracks steps, calories, distance, sleep and can tag activities including swimming, tennis, football and more.

The Shine 2 is made from anodised aircraft grade aluminium and measures 8mm in the centre and 3.3mm around the edges. It is water resistant to 50 metres and uses a replaceable watch battery for six months of constant use.

Returning are the 12 LED lights that can be used for notifications as well as telling the time. But now these are colour lights with over six million colour variations available.

Added to that is a new vibration motor for more alert options. That means the Shine 2 can alert the wearer to calls or messages on a connected phone. But it also acts as a smart alarm. Since the Shine 2 tracks deep and light sleep patterns, automatically, it's able to wake the wearer during a light sleep so it feels natural and refreshing.

The Bluetooth is upgraded to 4.1 for faster connectivity with phones as well as longer range, says Misfit. The tap and touch sensitive button is also more accurate than its predecessor allowing for easier control of the connected phone and Misfit Link app. This app allows controls of music, the phone's camera and IFTTT home controls.

The Misfit Shine 2 comes in Carbon Black or Rose Gold and includes a sport band, clasp and action clip for the $100 price. Units are available worldwide from 1 November.
