Connect With your Health With the Fitbit Sense in Sage Grey

Whether you’re gearing up for the trails, heading to the pool at the gym or hopping on the indoor bicycles, tracking your fitness and wellness is a must. Instead of letting your hours of walking and running go unnoticed, keep your physical fitness in check with the Fitbit Sense in sage grey. This neutral-hued fitness tracker can accessorize nearly any outfit, from business casual ensembles to workout gear. Wear yours all day to keep tabs on different aspects of your health, with help from apps like ECG scanners and sleep trackers. Learn more about everything this stylish wristwear can do for you below.


For More Than Just Workouts

The Fitbit Sense isn’t just for high-intensity workouts. Explore all the available health features, like the EDA scan app. This detects electrodermal activity, which can indicate your body’s response to stress. Once you know what stresses you out, make a note of it after the scan is complete in the Fitbit app. That way, you can reflect on what makes you feel bad or better later on.

Meanwhile, built-in smart features can be used all day long. Notifications from messages, apps and phone calls keep you completely connected even when your smartphone isn’t in your hand. With access to Google Assistant and Alexa, you’ll be able to respond on an Android device in a flash. Nearly anything you can do with your phone you can do with your watch, from paying remotely to storing and playing music right on your wrist.


When it comes to battery life, the Fitbit Sense outlasts the competition. When GPS is off, this tiny device can last as long as six days before needing to be recharged. And even then, a charging session takes only 12 minutes for 24 hours of battery life. You’ll be ready to go as quickly as possible. Head out the door and hop on the train or hit the pavement. Whether you’re going to work or heading for a workout, this wearable technology will be with you every step of the way.
