Fitbit has followed up its popular Flex wristband with the Bluetooth 4.0 enabled Fitbit Force. The wireless activity accessory includes most of the same features as its predecessor, but adds a new OLED display. The Force accurately measures steps, distance, calories burned, and contains an altimeter to track how high you climb each day.
The Force is also equipped with a sleep monitoring and silent wake alarm that tracks how many hours you slept, and it allows users to stay motivated with online and mobile badges and leaderboards.
iOS 7 users will be able to take advantage of the Force's new "smart call notifications." Users can choose to receive real-time incoming alerts on their Force when their iPhone 4s or higher is nearby.
The Fitbit Force is now available from Fitbit.com for $130. It will also be available from select retailers in "two-three weeks."
