Fitbit Charge 2
If you need to know your heart rate all the time, plus fitness and sleep data in a wearable device that delivers week-long battery life and can deliver Caller ID notifications the Fitbit Charge 2 is a good option.
"The 5-6 day battery life is killer, you can get on with your life without constantly having to wonder if it’s going to die on you," explains Tobias Buckell, NYT Best Selling Author, speaking about the previous version adding "It takes minutes to recharge to just emergency levels if in a hurry and getting sleep data and near-constant heart rate data throughout the day is a killer feature."
With the Fitbit Charge 2 users can track workouts plus all day activity including heart rate, steps, distance, calories burned, stairs climbed and time spent active. When you need to work out, the exercise mode delivers real-time stats on your wrist. The sleep tracking can wake you with a silent vibrating alarm in the morning and help you identify sleep trends. You can also connect with friends for competition to keep everyone motivated. All of this data syncs wirelessly to the iPhone and Android.
The Fitbit Charge 2 is $149.99 at Amazon and comes in multiple sizes.
