Fitbit unveils Charge 2 and Flex 2 activity trackers

Today Fitbit has finally decided to update its Charge fitness tracker line, after nearly two years since the original models were outed. The new Fitbit Charge 2 comes with a built-in heart rate monitor (so the more expensive HR option is gone this time), as well as something the company calls 'connected GPS'. This means that when the wearable is connected to your phone, it will be able to use that device's location information to record a map of your route and give you real-time stats like pace and distance.
