What to Look for in a Fitbit Fitness Tracker:

Battery Life- When you're working out or tracking your daily activity, it can be a challenge to remember to keep your Fitbit charged. All of their products offer battery life that lasts several days, with some offering up to a whole week of use. This allows you to better monitor your progress without constantly needing to recharge your device.
Tracking Metrics- Each Fitbit model tracks your wellness in different ways. Some claim to offer 24/7 monitoring of your heart rate, calories burned, and steps taken while others give you only daily snapshots. There are even models that give you reminders to get up and move if you've been inactive for a period of time or to drink water to keep hydrated.
GPS- Having a GPS function could be important to those who hike or train for marathons. Most Fitbit models tether to your smartphone to use its GPS function, though there are a few with native GPS capabilities. Tracking your location could give some people greater control over tracking their progress and keeping safe in emergency situations.
