A:AnswerI think it’s mostly the readiness score and perhaps more advanced reporting. The premium also comes with guided workouts, articles, and mental wellness / mindfulness cirricula.
A:AnswerNo the Inspire 2 only comes with the wrist band. A clip on can be purchased separately. Unknown if Best Buy offers it though. The clip counts the steps but without contact to your wrist the heart rate will not register.
A:AnswerYou could replace the battery if you are adept at using a soldering iron. However you would probably run the risk of voiding any warranty and potentially damaging the Fitbit in the process. These batteries generally have a long life span.
A:AnswerNo, you don’t have to sign up for a service to use this device. However, I did sign up for Fitbit Premium. You don’t need it to keep track of your basic information: steps, heart beat, sleep tracking. I have enjoyed the extra insights Fitbit Premium provides: stress management, greater sleep information such as breathing rate, heart rate variability, skin temperature, and resting heart rate—information that gives me greater insight on sleep. I am diagnosed with Sleep Apnea, so this information helps me understand my illness.
