Easily keep track of your health and movement with the Fitbit Inspire 3 Black. This activity tracker constantly measures your steps, burned calories, and heart rate. That way, you can check if you've moved enough every day at a glance. The Inspire 3 also keeps track of your stress level and sleep score, even though that's a bit less accurate than with watches like the Fitbit Versa and Sense. When you connect your Fitbit to your smartphone, you can keep record of your walked distance via the GPS of your smartphone. You can also view incoming messaged and notifications on your Fitbit. The battery lasts 10 days. If you work out a lot, the daily recovery score indicates if your body is ready to work out again, or if it needs more rest. You need a Fitbit Premium subscription for this. Note: you have to pay for this.
