Towards the end of March, Fitbit announced the Charge HR and Surge, new additions to its activity-tracking family. The Charge HR is an enhanced version of the Charge, just with a heart rate monitor added on (clever). The Surge is the Cadillac version that comes with a giant, black and white touch screen. The former goes for $149.99, while the latter goes for a hundred bucks more. Both are now shipping in North America, which a global release soon to follow.

Fitbit is also adding a few enhancements to its fitness platform. Soon owners will be able to link up to five trackers to a single account. The company is looking to connect more users through Public Challenges, and folks will be able to find friends through email search or Facebook Friend Finder. More badges are coming, and they will find their way into the mobile app.

The food logging experience isn't going without attention either. People in the US can add items just by scanning barcodes with the mobile app, a feature that's on its way to folks in Australia, Canada, China, France, Germany, Italy, Korea, Mexico, Spain, and the UK.
